Efficiency was measured by Cm-248 source to 4158600100025 be 39 %. 4158600100026 Neutron detector efficiency was measured before and 4158600100027 after main measurement in beam, using Cm-248 source, 4158600100028 and was found to be from 36 to 39%. 4158600100029 (SISD) Five 16-strip (58mmx58mm) Si detectors set to 4158600100030 detect FF and alphas. Energy resolution (measured in 4158600100031 tests) is about 20 keV (focal detector) and about 4158600100032 150 keV (side detectors, FF and alphas registration). 4158600100033 Geometry efficiency about 85 % (for alphas) 4158600100034 STATUS (SPSDD,41579001) See HISTORY 2015-07-10. 4158600100035 HISTORY (20120503C) M.M. 4158600100036 (20150710A) Subents 002,003 were deleted as duplication4158600100037 of Subents 41579.005, .006 . 4158600100038 Essential information was moved in Entry 41579. 4158600100039 ENDBIB 37 0 4158600100040 NOCOMMON 0 0 4158600100041 ENDSUBENT 40 0 4158600199999 NOSUBENT 41586002 20150710 41694158600200001 NOSUBENT 41586003 20150710 41694158600300001 ENDENTRY 3 0 4158699999999
