TG-60 dosimetry parameters calculation for the β-emitter 153Sm brachytherapy source using MCNP
Background: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for β sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. In this work the dosimetry parameters of the ...
متن کاملThe Rf Source of the 60-mev Linac for the Kek/jaeri Joint Project
The construction of the 60-MeV proton linac has started as a low-energy front of the KEK/JAERI Joint Project for a high-intensity proton accelerator facility at KEK. The accelerating frequency is 324 MHz. Five UHF klystrons are used as an rf source; their ratings have a maximum power of 3 MW, a beam pulse width of a 700 μsec (an rf pulse width is 650 μsec) and a repetition rate of 50 pps. We ha...
متن کاملBremsstrahlung of relativistic electrons in the Aharonov-Bohm potential.
Abstract We investigate the scattering of an electron by an infinitely thin and infinitely long straight magnetic flux tube in the framework of QED. We discuss the solutions of the Dirac and Maxwell fields in the related external pure AB potential and evaluate matrix elements and differential probabilities for the bremsstrahlung process. The dependence of the resulting cross section on the ener...

متن کاملOn the Calculation of Gluon Bremsstrahlung in Qcd
It is shown that several published calculations of the process e+e--+ Gq;i in the one-photon exchange approximation are in error. The calculations are all (at least) missing a factor of 2/x3 in the differential cross section do/dxldx2 in the rest frame of the virtual photon, where x i &Y/2 is the energy of the particle i in the final state in this frame and particle 3 is the gluon G. The reason...
