A Bremsstrahlung converter for medical apparatuses sterilization has been designed using tantalum and stainless-steel frame a high energy electron accelerator operating at an incident of 7.5 MeV. Optimization the x-ray spectra is investigated in this paper by adding beam hardening filter from copper, aluminum, stainless steel. The MCNP code used to simulate particle transport through design. To...

Medical isotopes can be produced by reactors and accelerators [1]. For certain isotopes there could be an advantage to a certain production method. For example; in some cases production via the ( ,n) or ( ,p) reaction has advantages that include high production yield [2] and production in a matrix that simplifies chemical separation of the desired isotope. To maximize isotope production, a high...

A design study of a 7 MeV/u C injector LINAC for a synchrotron for light-ion tumour therapy is presented. The injector consists of a 14.5 GHz ECR ion source, a LEBT line, a 216 MHz RFQ structure of 1.2 m length for acceleration from 6 keV/u to 300 keV/u and a subsequent 216 MHz IH drift tube LINAC of 4.0 m length for acceleration to 7 MeV/u. The IH structure consists of four drift tube sections...

Heavy ions show the excellent dose concentration especially at a position located deep in a human body. This character of heavy ions are well suited for the medical treatment of the cancer. A heavy ion synchrotron complex, HIMAC, has been constructed at NIRS for this purpose. The HIMAC accelerator consists of an injector linac, a couple of synchrotron rings, long and complicated beam transport ...

PAMELA (Particle Accelerator for MEdicaL Applications) is a design study of a novel accelerator for cancer therapy using protons and carbon ions. The accelerator utilizes the nonscaling Fixed Field Alternating Gradient (FFAG) principle and features superconducting combined-function magnets with dipole, quadrupole, sextupole and octupole field components for steering the ion beam. The proton rin...

Algebraic reconstruction techniques require about half the number of projections as that of Fourier backprojection methods, which makes these methods safer in terms of required radiation dose. Algebraic reconstruction technique (ART) and its variant OS-SART (ordered subset simultaneous ART) are techniques that provide faster convergence with comparatively good image quality. However, the prohib...
