A062700100017 (EXTB,EDE,BCINT) A062700100018 DETECTOR (TELES,SIBAR,SIBAR) A062700100019 In the present approach four deltaE-E telescopes are A062700100020 placed (in the rectangular target chamber) around the A062700100021 beam axis at a distance of 2.5 and 3.5 cm from the beamA062700100022 axis. Each telescope consists of transmission surface A062700100023 barrier detectors with a 0.25 um Al layer deposited A062700100024 on both sides of the detectors. The deltaE and A062700100025 E detectors (micron) have both an active (square) area A062700100026 of 2500 mm2; the deltaE detector (105 keV energy A062700100027 resolution at Ealpha= 5.5 MeV) has a thickness of A062700100028 140 um and the E detector (55 keV energy resolution at A062700100029 Ealpha= 5.5 MeV) has a thickness of 1000 um (maximum A062700100030 available thickness). A mylar foil and an al foil (eachA062700100031 of 1.5 um) are placed in front of each telescope. A062700100032 HISTORY (19990601C) By F.C. A062700100033 (19990609U) Last checking has been done.
