C2724 1 15 SAMPLE Windowless gas target filled with H2 gas at 6.66 mbar. C2724 1 16 DETECTOR (BGO) Array of 30 bismuth germanate (BGO) detectors C2724 1 17 surrounding the gas target was used to detect gamma C2724 1 18 rays resulting from (p,gamma) reactions C2724 1 19 (MAGSP) 27Si recoils were momentum analyzed by DRAGON C2724 1 20 magnetic and electrostatic dipole systems and C2724 1 21 transmitted to the focal plane of DRAGON. C2724 1 22 (TELES,MCPLT,IOCH)Recoils were identified using a localC2724 1 23 time-of-flight (TOF) system based on two microchannel C2724 1 24 plates and an isobutane-filled ionization chamber. C2724 1 25 (NAICR) Positrons from decay of 26mAl were guided to C2724 1 26 the pair of NaI(Tl) detectors. By comparing the number C2724 1 27 of coincident 511-keV annihilation rays with GEANT4 C2724 1 28 simulations of the NaI detector response, an average C2724 1 29 26mAl beam intensity of was determined C2724 1 30 METHOD (TOF,EDE) C2724 1 31 INC-SOURCE Unstable 26Al was produced by bombarding a thick SiC C2724 1 32 production target with up to 70 mu-A of 500 MeV protonsC2724 1 33 from TRIUMF's cyclotron and initially accelerated to C2724 1 34 energies of 150 AkeV using a radio-frequency quadrupoleC2724 1 35 accelerator. This beam was then stripped to a higher C2724 1 36 charge state and further accelerated using drift tube C2724 1 37 linac.
