O145900100010 FACILITY (ACCEL,4RUSITE) The ITEP proton clinical facility. O145900100011 METHOD (EXTB) For the experiment, beams with initial energiesO145900100012 of 100, 130, 180 and 200 MeV were used without O145900100013 additional energy degradation. The energy of the beamO145900100014 incident on the target was determined more accurately O145900100015 by measuring the beam range in a water phantom. O145900100016 A small correction was applied to the incident energy O145900100017 to correct to the energy of protons at the center ofO145900100018 the target. O145900100019 (BCINT) A current monitor was used to monitor the O145900100020 intensity of the beam. The monitor operates as a O145900100021 current transformer and measures a value proportional O145900100022 to the number of charged particles passing through itsO145900100023 aperture. O145900100024 (ACTIV,BGCT) O145900100025 DETECTOR (SPEC) Activated targets were placed in the detection O145900100026 assembly designed at ITEP. This unit measures O145900100027 beta-gamma-coincidences: one channel detects O145900100028 scintillations of positron decay, while the other is O145900100029 for gamma-ray detection. The detecting element in the O145900100030 beta-channel consists of the target itself and a O145900100031 polystyrene scintillation assembly surrounding the O145900100032 target. The walls of the assembly are thick enough to O145900100033 stop all positrons emitted from the target. Thus, the O145900100034 geometry of the beta-detector is close to 4-pi. O145900100035 Annihilation gamma-rays are detected in the O145900100036 gamma-channel with a NaI(Tl) crystal. The geometry of O145900100037 the gamma-detector is close to 2pi.
