C272400100015 SAMPLE Windowless gas target filled with H2 gas at 6.66 mbar. C272400100016 DETECTOR (BGO) Array of 30 bismuth germanate (BGO) detectors C272400100017 surrounding the gas target was used to detect gamma C272400100018 rays resulting from (p,gamma) reactions C272400100019 (MAGSP) 27Si recoils were momentum analyzed by DRAGON C272400100020 magnetic and electrostatic dipole systems and C272400100021 transmitted to the focal plane of DRAGON. C272400100022 (TELES,MCPLT,IOCH)Recoils were identified using a localC272400100023 time-of-flight (TOF) system based on two microchannel C272400100024 plates and an isobutane-filled ionization chamber. C272400100025 (NAICR) Positrons from decay of 26mAl were guided to C272400100026 the pair of NaI(Tl) detectors. By comparing the number C272400100027 of coincident 511-keV annihilation rays with GEANT4 C272400100028 simulations of the NaI detector response, an average C272400100029 26mAl beam intensity of was determined C272400100030 METHOD (TOF,EDE) C272400100031 INC-SOURCE Unstable 26Al was produced by bombarding a thick SiC C272400100032 production target with up to 70 mu-A of 500 MeV protonsC272400100033 from TRIUMF's cyclotron and initially accelerated to C272400100034 energies of 150 AkeV using a radio-frequency quadrupoleC272400100035 accelerator. This beam was then stripped to a higher C272400100036 charge state and further accelerated using drift tube C272400100037 linac.
