Application of Charged-Particle beams in science and technology
La Rivista del Nuovo Cimento (1978-1999), 1992Co-Authors: V. Valkovic, G. MoschiniAbstract:Charged-Particle beams are assuming an evermore prominent role in our everyday life. For example, today it is difficult to envisage a research centre in biomedical sciences or a contemporary hospital without the access to a Particle accelerator. With future development in technology and our better understanding of Charged-Particle interaction with living matter the role of accelerators in life sciences will increase even more. Equally important are studies of new materials and applications of unique analytical capabilities of nuclear probes.

Radiation from a Charged Particle and radiation reaction reexamined
Physical Review D, 1998Co-Authors: Abhinav Gupta, Thanu PadmanabhanAbstract:We study the electromagnetic fields of an arbitrarily moving Charged Particle and the radiation reaction on the Charged Particle using a novel approach. We first show that the fields of an arbitrarily moving Charged Particle in an inertial frame can be related in a simple manner to the fields of a uniformly accelerated Charged Particle in its rest frame. Since the latter field is static and easily obtainable, it is possible to derive the fields of an arbitrarily moving Charged Particle by a coordinate transformation. More importantly, this formalism allows us to calculate the self-force on a Charged Particle in a remarkably simple manner. We show that the original expression for this force, obtained by Dirac, can be rederived with much less computation and in an intuitively simple manner using our formalism.

Charged-Particle emission tomography
Medical physics, 2017Co-Authors: Yijun Ding, Luca Caucci, Harrison H. BarrettAbstract:Purpose Conventional Charged-Particle imaging techniques — such as autoradiography — provide only two-dimensional (2D) black ex vivo images of thin tissue slices. In order to get volumetric information, images of multiple thin slices are stacked. This process is time consuming and prone to distortions, as registration of 2D images is required. We propose a direct three-dimensional (3D) autoradiography technique, which we call Charged-Particle emission tomography (CPET). This 3D imaging technique enables imaging of thick tissue sections, thus increasing laboratory throughput and eliminating distortions due to registration. CPET also has the potential to enable in vivo Charged-Particle imaging with a window chamber or an endoscope. Methods Our approach to Charged-Particle emission tomography uses Particle-processing detectors (PPDs) to estimate attributes of each detected Particle. The attributes we estimate include location, direction of propagation, and/or the energy deposited in the detector. Estimated attributes are then fed into a reconstruction algorithm to reconstruct the 3D distribution of Charged-Particle-emitting radionuclides. Several setups to realize PPDs are designed. Reconstruction algorithms for CPET are developed. Results Reconstruction results from simulated data showed that a PPD enables CPET if the PPD measures more attributes than just the position from each detected Particle. Experiments showed that a two-foil Charged-Particle detector is able to measure the position and direction of incident alpha Particles. Conclusions We proposed a new volumetric imaging technique for Charged-Particle-emitting radionuclides, which we have called Charged-Particle emission tomography (CPET). We also proposed a new class of Charged-Particle detectors, which we have called Particle-processing detectors (PPDs). When a PPD is used to measure the direction and/or energy attributes along with the position attributes, CPET is feasible.
