C2855001 15 FACILITY (LINAC,1CANTMF) Experiment carried out using the C2855001 16 DRAGON recoil separator at TRIUMF, Vancouver C2855001 17 SAMPLE Helium-filled DRAGON windowless gas target with C2855001 18 effective length of (12.3+-0.1) cm and He pressure C2855001 19 between 4.92 and 7.9 torr. C2855001 20 DETECTOR (MAGSP) For mass and momentum selection an C2855001 21 electromagnetic mass separator was used, which C2855001 22 consists of two magnetic (M) and two electric dipoles C2855001 23 (E) in a MEME configuration. C2855001 24 (BGO) Prompt gamma rays were detected using an array C2855001 25 of 30 BGO scintillators with phototubes covering C2855001 26 covering 89-92% of the 4Pi solid angle. It was used C2855001 27 also fore tagging of the associated recoil particles C2855001 28 for additional background reduction in the focal C2855001 29 plane detectors. C2855001 30 (MCPLT,SISD) Focal plane detector consisting of C2855001 31 microchannel plate and a double-sided silicon-strip C2855001 32 detector. The microchannel plate provided the C2855001 33 starting timing sig nalfor a local time-of-flight. In C2855001 34 the Si strip detector the recoils are stopped, their C2855001 35 kinetic energy and position are measured, and the C2855001 36 stopping timing signal is recorded. C2855001 37 METHOD (TOF) C2855001 38 INC-SOURCE Beams of 7Be+ were produced using the ISOL technique C2855001 39 by bombarding thick ZrC and graphite targets with 55 C2855001 40 muA 500 MeV protons from the TRIUMF cyclotron. 7Li C2855001 41 and 7Be were extracted from the target through a C2855001 42 high- resolution mass separator, and the beryllium C2855001 43 ionization was enhanced using the TRIUMF Resonant C2855001 44 Ionization Laser Ion Source. After the ion source, C2855001 45 the beam was transported through the ISAC C2855001 46 high-resolution mass separator and then accelerated C2855001 47 through the ISAC-I radio frequency quadrupole and C2855001 48 drift-tube linac to final energy.
