  • Imaging characteristics of glass capillary plate Gas Detector
    Nuclear Instruments and Methods in Physics Research Section A: Accelerators Spectrometers Detectors and Associated Equipment, 2010

    Abstract:

    Abstract A glass capillary plate (CP) Gas Detector with Gas mixtures of He, Ne, Ar, and Xe has been successfully operated as a visible and near-infrared (NIR) scintillation proportional counter. Gas gains of up to 10 4 can be achieved using these Gas mixtures. The scintillation light emitted during the generation of electron avalanches can be observed using a photomultiplier tube (PMT) and a compact optical imaging system that consists of a CP Gas Detector and a cooled CCD camera coupled to lens optics. Using this optical imaging system, clearer X-ray images have been obtained with the above Gas mixtures. The dependence of the imaging quality on the pressure in the range 0.25–1 atm was also investigated for the Ar (90%)+CF 4 (10%) Gas mixture. The successful operations using these Gas mixtures have allowed us to realize a novel imaging device with a CP Gas Detector for Gaseous PMTs sensitive to visible light.

    Abstract:

    A capillary plate (CP) Gas Detector with fiber optic plate (FOP) has been successfully operated as a Gas scintillation proportional counter. A thin film of indium tinoxide (ITO) was used for the transparent electrode of the CP. Scintillation light emitted during the development of electron avalanches can be observed through the FOP using a photomultiplier tube (PMT) and an optical imaging system, which consists of a CP Gas Detector and a cooled CCD camera coupled to lens optics. Using this optical imaging system, clearer images of X-rays have been obtained.

  • Performance of optical imaging capillary plate Gas Detector with synchrotron radiation
    IEEE Transactions on Nuclear Science, 2006
    Co-Authors: Fuyuki Tokanai, Hirohisa Sakurai, Shuichi Gunji, H. Toyokawa, M. Suzuki, H. Tanida, S. Kishimoto
    Abstract:

    We have been developing an X-ray photoelectron tracking imager based on a glass capillary plate (CP) Gas Detector for cosmic X-ray polarimetry applications. The optical imaging system consists of a CP Gas Detector filled with a noble-Gas mixture and a cooled CCD camera coupled to an optical lens system. The performance of the optical imaging CP Gas Detector as an X-ray polarimeter was investigated with highly polarized, well-monochromized, and well-collimated X-ray beams at the synchrotron radiation facilities in SPring-8 and KEK-PF. Owing to the fine imaging capability of the optical imaging CP Gas Detector, images of X-ray photoelectron tracks were clearly observed for the polarized X-rays. A modulation factor of 26% was obtained for a 15 keV polarized X-ray beam, for which the energy resolution was 13%. We report on the properties of the optical imaging CP Gas Detector as an X-ray polarimeter and describe the outlook on future developments on the basis of the measured characteristics and the results of Monte Carlo simulations.

    Abstract:

    Abstract An optical imaging capillary plate (CP) Gas Detector has been successfully developed for a Gas mixture of Ar+CF4. Gas gains of up to 104 can be achieved with a single CP. Scintillation light simultaneously emitted during the development of electron avalanches can be observed using a photomultiplier tube (PMT) and optical imaging system which consists of a CP Gas Detector and a cooled CCD camera coupled to lens optics. The energy resolutions obtained for the charge signal and the light signal were 22% and 24% for 10 keV X-rays, respectively. Using the optical imaging system, clearer images of X-rays have been obtained with the Gas mixture. Successful operation with this Gas mixture has allowed us to realise a novel-imaging device with CP for X-ray imaging, cold neutron imaging, medical imaging, and cellular function analysis.

  • A scintillating Gas Detector for 2D dose measurements in clinical carbon beams
    Physics in medicine and biology, 2008
    Co-Authors: E Seravalli, M. De Boer, F Geurink, J. Huizenga, R. Kreuger, Jacobus M. Schippers, C.w.e. Van Eijk, B Voss
    Abstract:

    A two-dimensional position sensitive dosimetry system based on a scintillating Gas Detector has been developed for pre-treatment verification of dose distributions in hadron therapy. The dosimetry system consists of a chamber filled with an Ar/CF4 scintillating Gas mixture, inside which two cascaded Gas electron multipliers (GEMs) are mounted. A GEM is a thin kapton foil with copper cladding structured with a regular pattern of sub-mm holes. The primary electrons, created in the Detector's sensitive volume by the incoming beam, drift in an electric field towards the GEMs and undergo Gas multiplication in the GEM holes. During this process, photons are emitted by the excited Ar/CF4 Gas molecules and detected by a mirror-lens-CCD camera system. Since the amount of emitted light is proportional to the dose deposited in the sensitive volume of the Detector by the incoming beam, the intensity distribution of the measured light spot is proportional to the 2D hadron dose distribution. For a measurement of a 3D dose distribution, the scintillating Gas Detector is mounted at the beam exit side of a water-bellows phantom, whose thickness can be varied in steps. In this work, the energy dependence of the output signal of the scintillating Gas Detector has been verified in a 250 MeV/u clinical 12C ion beam by means of a depth–dose curve measurement. The underestimation of the measured signal at the Bragg peak depth is only 9% with respect to an air-filled ionization chamber. This is much smaller than the underestimation found for a scintillating Gd2O2S:Tb ('Lanex') screen under the same measurement conditions (43%). Consequently, the scintillating Gas Detector is a promising device for verifying dose distributions in high LET beams, for example to check hadron therapy treatment plans which comprise beams with different energies.

  • Soda-glass capillary plate Gas Detector
    IEEE Transactions on Nuclear Science, 2005
    Co-Authors: Fuyuki Tokanai, Shuichi Gunji, Takuji Atsumi, Teruyuki Okada, Hirohisa Sakurai
    Abstract:

    A new capillary plate (CP) has been developed for a hole-type micropattern Gas Detector. The plate consists of a bundle of fine soda-glass capillaries with a diameter of 100 /spl mu/m and a length of 1 mm. The electrodes on the surfaces of both ends of CP were coated with Inconel metal. The plate is similar to a conventional CP, except that the material used is not lead glass, but soda glass. The main advantages of the soda-glass CP compared to the lead-glass CP are a low surface resistivity and low background properties. The soda-glass CP Gas Detector was operated with a Gas mixture of Ar(90%) + CH/sub 4/(8%) + TMA(2%) using 5.9 keV X-rays. Using the scintillation light emitted from the soda-glass CP, we successfully obtained the energy spectrum and accumulated image for the 5.9 keV X-rays. In this paper, we report on the characteristics of the new soda-glass CP and the background properties of both the soda-glass and lead-glass CPs. We also describe the outlook on the future development of an optical Gas photomultiplier with the soda-glass CP.
