C186900100010 #doi:10.1103/PhysRevC.84.045802 C186900100011 (C,2012CAIRNS,1,044,2012) Description of a bigger C186900100012 project with more authors, same data in graphical C186900100013 form, no other numerical data. C186900100014 FACILITY (LINAC,1USAANL) Experiment performed at the ATLAS C186900100015 facility at Argonne National Laboratory C186900100016 SAMPLE CH2 target with thickness of a 650 mu-g/cm2. C186900100017 DETECTOR (SISD)The alpha particles were detected C186900100018 in a 1000 mu-m thick annular double-sided Si detector C186900100019 (DSSD) with a back plane segmented into 16 wedges and C186900100020 a front plane divided into 16 rings segmented in C186900100021 theta(lab). The detector was placed such that the 16 C186900100022 rings covered an angular range of theta(lab) between C186900100023 8deg and 25deg with respect to the target. C186900100024 (MAGSP,PGAC,IOCH) The 30S reaction products were C186900100025 separated from the main beam (33Cl and 32S), and C186900100026 other reaction products by an Enge split-pole magnetic C186900100027 spectrograph. The particles were detected by an xy C186900100028 position-sensitive parallel grid avalanche counter C186900100029 and ionization chamber located at the focal plane of C186900100030 the spectrograph and filled with 5 Torr of isobutane C186900100031 and 15 Torr of CF4 gas, respectively. The PGAC C186900100032 measured the time of flight and the focal-plane C186900100033 position (or magnetic rigidity) of the particles, and C186900100034 the IC gave the energy loss in the gas, allowing C186900100035 rudimentary particle identification. C186900100036 METHOD (COINC) Alpha particles and 30S reaction products C186900100037 were detected in coincidence to avoid detection of C186900100038 scattered beam. Inverse kinematics was used with C186900100039 radioactive 33Cl beam C186900100040 INC-SOURCE 33Cl beam was produced using the in-flight method. A C186900100041 320-MeV primary beam of stable 32S13+ was incident on C186900100042 a gas cell, which was cryogenically cooled to -184 C186900100043 deg C and filled with 1.4 atm of D2 gas. The C186900100044 d(32S,33Cl)n reaction produced the desired C186900100045 radioactive 33Cl ions, which were emitted in a cone C186900100046 of 2.5deg. A 20 mu-g/cm2 carbon stripping foil was C186900100047 located immediately following the gas cell to C186900100048 increase the charge state fraction of fully stripped C186900100049 33Cl17+. The ions were then focused with a C186900100050 superconducting solenoid and rebunched with a C186900100051 superconducting resonator. After a 22 deg bending C186900100052 magnet was used, a cocktail beam remained, which C186900100053 consisted mostly of the different charge states of C186900100054 the primary 32S beam and the secondary 33Cl17+ beam. C186900100055 After a radio-frequency (RF) sweeper was used, the C186900100056 32S to 33Cl ratio of approximately 1.4:1. The final C186900100057 beam consisted of the secondary 33Cl17+ ions at 250 C186900100058 MeV and the low-energy tails of the primary beam with C186900100059 different charge states C186900100060 ERR-ANALYS (ERR-1,0.0,13.0) Systematic uncertainty in beam C186900100061 current, which dominated total uncertainty C186900100062 (ERR-2) Syst. uncertainty in background subtraction C186900100063 (ERR-T) Total uncertainty C186900100064 HISTORY (20111029C) Compiled by S.H.
