  • Measurement of therapeutic photon beams-induced Cerenkov Radiation generated in PMMA- and PS-based plastic optical fibers
    Optical Review, 2016
    Co-Authors: Sang Hun Shin, Kyoung Won Jang
    Abstract:

    In this study, we characterized Cerenkov Radiation generated in polystyrene (PS)- and polymethyl methacrylate (PMMA)-based plastic optical fibers (POFs) to select an adequate optical fiber for producing Cerenkov Radiation. To determine the relationship between the absorbed dose and the intensity of Cerenkov Radiation, we calculated the energy depositions of photon beams and fluxes of electrons inducing Cerenkov Radiation using the Monte Carlo N-Particle eXtended code. Also, intensities of Cerenkov Radiation generated in PS- and PMMA-based POFs were measured as functions of dose rate and monitor unit. At last, therapeutic photon beams-induced Cerenkov Radiation in PS- and PMMA-based POFs was measured according to depths of solid water phantom.

    Co-Authors: Jae Seok Kim, Sang Hun Shin, Kyoung Won Jang, Wook Jae Yoo, Bongsoo Lee, Seon Geun Kim, Dayeong Jeon, Seunghan Hong, Hyeok In Sim, Joohyun Moon
    Abstract:

    In this study, a Cerenkov Radiation sensor for detecting low-energy beta-particles was fabricated using various Cerenkov radiators such as an aerogel and CaF2-, SiO2-, and Al2O3-based optical glasses. Because the Cerenkov threshold energy (CTE) is determined by the refractive index of the Cerenkov radiator, the intensity of Cerenkov Radiation varies according to the refractive indices of the Cerenkov radiators. Therefore, we measured the intensities of Cerenkov Radiation induced by beta-particles generated from a radioactive isotope as a function of the refractive indices of the Cerenkov radiators. Also, the electron fluxes were calculated for various Cerenkov radiators by using a Monte Carlo N-Particle extended transport code (MCNPX) to determine the relationship between the intensities of the Cerenkov Radiation and the electron fluxes.

  • measurements of longitudinal gamma ray distribution using a multichannel fiber optic Cerenkov Radiation sensor

    Co-Authors: S H Shin, Kyoung Won Jang, Wook Jae Yoo, Dayeong Jeon, Jae Seok Kim, Jae Seok Jang, Joohyun Moon, B G Park, Sin Kim, Bongsoo Lee
    Abstract:

    Cerenkov Radiation occurs when charged particles are moving faster than the speed of light in a transparent dielectric medium. In optical fibers, Cerenkov Radiation can also be generated due to the fiber?s dielectric components. Accordingly, the Radiation-induced light signals can be obtained using the optical fibers without any scintillating material. In this study, we fabricated a multichannel, fiber-optic Cerenkov Radiation sensor (FOCRS) system using silica optical fibers (SOFs), plastic optical fibers (POFs), an optical spectrometer, multi-anode photomultiplier tubes (MA-PMTs) and a scanning system to measure the light intensities of Cerenkov Radiation induced by gamma rays. To evaluate the fading effects in optical fibers, the spectra of Cerenkov Radiation generated in the SOFs and POFs were measured based on the irRadiation time by using an optical spectrometer. In addition, we measured the longitudinal distribution of gamma rays emitted from the cylindrical type Co-60 source by using MA-PMTs. The result was also compared with the distribution of the electron flux calculated by using the Monte Carlo N-particle transport code (MCNPX).

  • performance evaluation of a fiber optic Cerenkov Radiation sensor system using a simulated spent fuel assembly
    Journal of Sensor Science and Technology, 2014
    Co-Authors: Sang Hun Shin, Kyoung Won Jang, Wook Jae Yoo, Seunghyun Cho, Byung Gi Park, Bongsoo Lee
    Abstract:

    Abstract When the charged particle travels in transparent medium with a velocity greater than that of light in the same medium, the elec-tromagnetic field close to the particle polarizes the medium along its path, and then the electrons in the atoms follow the waveform ofthe pulse which is called as Cerenkov light or Radiation. This type of Radiation can be easily observed in a spent fuel storage pit. In opticalfibers, the Cerenkov light also can be generated due to their dielectric components. Accordingly, the Radiation-induced light signals canbe obtained using optical fibers without any scintillating material. In this study, to measure the intensities of Cerenkov Radiation inducedby gamma-rays, we have fabricated the fiber-optic Cerenkov Radiation sensor system using silica optical fibers, plastic optical fibers,multi-anode photomultiplier tubes, simulated spent fuel assembly and a scanning system. To characterize the Cerenkov Radiation gen-erated in optical fibers, the intensities of Cerenkov Radiation generated in the silica and plastic optical fibers were measured. Also, wemeasured the longitudinal distribution of gamma rays emitted from the Ir-192 isotope by using the fiber-optic Cerenkov Radiation sensorsystem and simulated spent fuel assembly.Keywords: Cerenkov Radiation, Fiber-optic sensor, Gamma ray, Ir-192 isotope, Simulated spent fuel assembly

  • Characterization of Cerenkov Radiation generated in silica and plastic optical fibers
    23rd International Conference on Optical Fibre Sensors, 2014
    Co-Authors: Kyoung Won Jang, Sang Hun Shin, Wook Jae Yoo, Seon Geun Kim, Bongsoo Lee
    Abstract:

    Cerenkov Radiation, which is produced by charged particles that pass through optical fibers with a velocity greater than that of light, is frequently regarded as a severe noise signal in a fiber-optic Radiation sensor consisting of a scintillator and an optical fiber. Since the spectral range of Cerenkov Radiation is very broad and covers that of light outputs from a scintillator, Cerenkov Radiation generated in optical fibers is also acquired by a photodetector. However, Cerenkov Radiation can be a significant signal when we measure the intensities of Cerenkov Radiation generated from fixed length of optical fibers because it is one of the signals induced by interactions between Radiations and optical fibers. In this study, gamma-ray induced Cerenkov Radiation generated in silica and plastic optical fibers was measured in order to select an efficient optical fiber for producing Cerenkov Radiation. The intensities and the spectra of Cerenkov Radiation generated in the optical fibers were measured using a spectrometer. As the results, the intensities of Cerenkov Radiation generated in silica and plastic optical fibers have peak wavelengths at approximately 500 nm. Also, the intensity of Cerenkov Radiation obtained using a plastic wavelength shifting fiber was the highest among all sample optical fibers.

  • spectroscopic separation of Cerenkov Radiation in high resolution Radiation fiber dosimeters
    Journal of Biomedical Optics, 2015
    Co-Authors: Arash Darafsheh, Rongxiao Zhang, Stephen C Kanick, Brian W Pogue, Jarod C Finlay
    Abstract:

    We have investigated Cerenkov Radiation generated in phosphor-based optical fiber dosimeters irra- diated with clinical electron beams. We fabricated two high-spatial resolution fiber-optic probes, with 200 and 400 μm core diameters, composed of terbium-based phosphor tips. A generalizable spectroscopic method was used to separate Cerenkov Radiation from the transmitted signal by the fiber based on the assumption that the recorded signal is a linear superposition of two basis spectra: characteristic luminescence of the phosphor medium and Cerenkov Radiation. We performed Monte Carlo simulations of the Cerenkov Radiation generated in the fiber and found a strong dependence of the recorded Cerenkov Radiation on the numerical aperture of the fiber at shallow phantom depths; however, beyond the depth of maximum dose that dependency is minimal. The sim- ulation results agree with the experimental results for Cerenkov Radiation generated in fibers. The spectroscopic technique used in this work can be used for development of high-spatial resolution fiber micro dosimeters and for optical characterization of various scintillating materials, such as phosphor nanoparticles, in ionizing Radiation fields of high energy. © The Authors.

  • separation of Cerenkov Radiation in irradiated optical fibers by optical spectroscopy
    Proceedings of SPIE, 2015
    Co-Authors: Arash Darafsheh, Rongxiao Zhang, Stephen C Kanick, Brian W Pogue, Jarod C Finlay
    Abstract:

    We studied Cerenkov Radiation generated in irradiated optical fibers and demonstrated a generic spectroscopic method for separation of Cerenkov Radiation from the transmitted signal in fiber optic dosimetry based on the assumption that the recorded signal is a linear superposition of two basis spectra: Cerenkov Radiation and characteristic luminescence of the phosphor medium. Experimentally, we evaluated this technique by using fiber optic probes irradiated by electron beams generated by a clinical linear accelerator. This method can be used for optical characterization of various scintillating materials, such as phosphor nanoparticles, in ionizing Radiation fields of high energy. We performed Monte Carlo simulations of the Cerenkov Radiation generated in the fiber and found a strong dependence of the recorded Cerenkov Radiation on the numerical aperture of the fiber at shallow phantom depths; however, beyond the depth of maximum dose that dependency is minimal. Our simulation results agree well with the experimental results for Cerenkov Radiation generated in fibers irradiated with 6 MeV electrons.

  • development of a Cerenkov Radiation sensor to detect low energy beta particles
    Applied Radiation and Isotopes, 2013
    Co-Authors: Wook Jae Yoo, Sang Hun Shin, Ki-tek Han, Dayeong Jeon, Jeong Ki Seo, Bongsoo Lee
    Abstract:

    We fabricated a novel fiber-optic Cerenkov Radiation sensor using a Cerenkov radiator for measuring beta-particles. Instead of employing a scintillator, transparent liquids having various refractive indices were used as a Cerenkov radiator to serve as a sensing material. The experimental results showed that the amount of Cerenkov Radiation due to the interaction with beta-particles increased as the refractive index of the Cerenkov radiator was increased as a results of a decrease of the Cerenkov threshold energy for electrons.

  • Measurement of Cerenkov Radiation Induced by the Gamma-Rays of Co-60 Therapy Units Using Wavelength Shifting Fiber
    Sensors, 2014
    Co-Authors: Kyoung Won Jang, Sang Hun Shin, Young Hoon Ji
    Abstract:

    In this study, a wavelength shifting fiber that shifts ultra-violet and blue light to green light was employed as a sensor probe of a fiber-optic Cerenkov Radiation sensor. In order to characterize Cerenkov Radiation generated in the developed wavelength shifting fiber and a plastic optical fiber, spectra and intensities of Cerenkov Radiation were measured with a spectrometer. The spectral peaks of light outputs from the wavelength shifting fiber and the plastic optical fiber were measured at wavelengths of 500 and 510 nm, respectively, and the intensity of transmitted light output of the wavelength shifting fiber was 22.2 times higher than that of the plastic optical fiber. Also, electron fluxes and total energy depositions of gamma-ray beams generated from a Co-60 therapy unit were calculated according to water depths using the Monte Carlo N-particle transport code. The relationship between the fluxes of electrons over the Cerenkov threshold energy and the energy depositions of gamma-ray beams from the Co-60 unit is a near-identity function. Finally, percentage depth doses for the gamma-ray beams were obtained using the fiber-optic Cerenkov Radiation sensor, and the results were compared with those obtained by an ionization chamber. The average dose difference between the results of the fiber-optic Cerenkov Radiation sensor and those of the ionization chamber was about 2.09%.

  • temporal separation of Cerenkov Radiation and scintillation using a clinical linac and artificial intelligence
    Physics in Medicine and Biology, 2018
    Co-Authors: Levi Madden, James Archer, Dean Wilkinson, Anatoly B Rosenfeld
    Abstract:

    Convolutional neural network (CNN) type artificial intelligences were trained to estimate the Cerenkov Radiation present in the temporal response of a LINAC irradiated scintillator-fiber optic dosimeter. The CNN estimate of Cerenkov Radiation is subtracted from the combined scintillation and Cerenkov Radiation temporal response of the irradiated scintillator-fiber optic dosimeter, giving the sole scintillation signal, which is proportional to the scintillator dose. The CNN measured scintillator dose was compared to the background subtraction measured scintillator dose and ionisation chamber measured dose. The dose discrepancy of the CNN measured dose was on average 1.4% with respect to the ionisation chamber measured dose, matching the 1.4% average dose discrepancy of the background subtraction measured dose with respect to the ionisation chamber measured dose. The developed CNNs had an average time of 3 ms to calculate scintillator dose, permitting the CNNs presented to be applicable for dosimetry in real time.

  • temporal separation of Cerenkov Radiation and scintillation using artificial neural networks in clinical linacs
    Physica Medica, 2018
    Co-Authors: Levi Madden, James Archer, Dean Wilkinson, Anatoly B Rosenfeld
    Abstract:

    The irRadiation of scintillator-fiber optic dosimeters by clinical LINACs results in the measurement of scintillation and Cerenkov Radiation. In scintillator-fiber optic dosimetry, the scintillation and Cerenkov Radiation responses are separated to determine the dose deposited in the scintillator volume. Artificial neural networks (ANNs) were trained and applied in a novel single probe method for the temporal separation of scintillation and Cerenkov Radiation. Six dose profiles were measured using the ANN, with the dose profiles compared to those measured using background subtraction and an ionisation chamber. The average dose discrepancy of the ANN measured dose was 2.2% with respect to the ionisation chamber dose and 1.2% with respect to the background subtraction measured dose, while the average dose discrepancy of the background subtraction dose was 1.6% with respect to the ionisation chamber dose. The ANNs performance was degraded when compared with background subtraction, arising from an inaccurate model used to synthesise ANN training data.
