O174800100020 FACILITY (SYNCH,2GERJUL) The ANKE-spectrometer at the internal O174800100021 beam of COSY-Julich. O174800100022 SAMPLE The hydrogen cluster jet target. O174800100023 DETECTOR (MAGSP).The ANKE-magnetic spectrometer. The set of O174800100024 used detectors includes: O174800100025 (TELES,SIBAR,MWPC,SCIN) The telescope comprises a O174800100026 set of three multiwire proportional chambers and a O174800100027 two-plane scintillation hodoscope, consisting of O174800100028 vertically oriented counters (eight in first plane, O174800100029 nine in second). The detector was used to record a O174800100030 fast proton pair emitted in the forward direction O174800100031 with small excitation energy (< 3 MeV). O174800100032 METHOD (TOF) O174800100033 (JET) O174800100034 (COINC) proton-proton coincidence O174800100035 ADD-RES (COMP).A full Monte Carlo simulation developed within O174800100036 the framework of the GEANT program.
