A0493001 25 The main constituent is the ionization chamber IKAR, A0493001 26 described in detail in REL-REF, filled with hydrogen A0493001 27 gas at a pressure of 10 bar. Beam particles interacted A0493001 28 with the protons inside IKAR, which thus served A0493001 29 simultaneously as a target and a recoil proton A0493001 30 detector. The recoil protons registered in IKAR were A0493001 31 measured in coincidence with the scattered A0493001 32 He particles. For the purpose of determining the A0493001 33 scattering angle of the He particles, a system of A0493001 34 tracking detectors was applied. It consisted of two A0493001 35 pairs of two-dimensional position-sensitive multi-wire A0493001 36 proportional chambers. A0493001 37 INC-SOURCE (SPALL) The helium ions produced by fragmentation of A0493001 38 18-O entered FRS and were separated according to their A0493001 39 magnetic rigidity. The beam intensities were 1000 A0493001 40 1/sec, with the duty factor between 25% and 50%. A0493001 41 COMMENT By authors.
