Research of radiation parameters of accelerator ARSA close to output window
Preliminary radiation research of accelerator ARSA of RISI close to output window for the purpose of its following certification is done. Dose profiles and dose rate in directions, perpendicular tube axes 3 mm away from a window are defined. Radiation yield stability is checked up. Distance dependences of effective pulse duration and amplitude correlation of the first and second peaks in an accelerator impulse on axis are defined. Measurements are made with dosimetric semiconductor detectors DSD2 on the basis of diode KD104A. Maximum pulse dose close to a output window was about 110 Р, maximum dose rate - about 2,5 · 1010 Р/с. The average radiation energy on absorption in TLD stubs on the basis of LiF is estimated
