- PP chamber fabrication to evaluate magnetic field response
In this study, PP type chamber will be fabricated using 3D printer. For this fabricated chamber, kQ factor is calculated and Fano cavity theorem is validated.
Fano cavity theorem describes the irradiated charged particle fluence is spatially uniform in a medium with uniform atomic properties, and also uniform independent of the mass density distribution. Radiation therapy in the circumstances of magnetic field may change because the behavior of secondary electrons is affected by B-field. Special conditions should be introduced for Fano’s theorem to hold in this situations such as ‘isotropic and spatially uniform sources’ or ‘spatially uniform sources and density-scaled magnetic field’. Also, various Monte Carlo simulation techniques are used to calculate the effect of magnetic field in dose calculation.
- Dual-particle imager based on RMC technique
As an attempt to develop a gamma-ray/neutron dual-particle imager, we employed rotating modulation collimators (RMC) coupled to a pulse shape discrimination (PSD)-capable scintillator. The proposed RMC system can be very effective tool which can compensate drawbacks of radiation imagers that is based only on the detection of one type of particles, and can be exploited for various applications.
