FACILITY (LINAC,1CANTMF) Detector of Recoils and Gammas of C272400100012
Nuclear Reactions was used to perform a direct C272400100013
measurement of the 26mAl(p,g) reaction at the ISAC-I C272400100014
radioactive beam facility at TRIUMF. 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. C272400100038
