C283500100021 DETECTOR (MAGSP) For mass and momentum selection an C283500100022 electromagnetic mass separator was used, which C283500100023 consists of two magnetic (M) and two electric dipoles C283500100024 (E) in a MEME configuration. C283500100025 (BGO) Prompt gamma rays were detected using an array C283500100026 of 30 BGO scintillators with phototubes covering C283500100027 covering 89-92% of the 4Pi solid angle. It was used C283500100028 also fore tagging of the associated recoil particles C283500100029 for additional background reduction in the focal C283500100030 plane detectors. C283500100031 (MCPLT,SISD) Focal plane detector consisting of C283500100032 microchannel plate and a double-sided silicon-strip C283500100033 detector. The microchannel plate provided the C283500100034 starting timing sig nalfor a local time-of-flight. In C283500100035 the Si strip detector the recoils are stopped, their C283500100036 kinetic energy and position are measured, and the C283500100037 stopping timing signal is recorded. C283500100038 METHOD (TOF) C283500100039 INC-SOURCE Beams of 7Be+ were produced using the ISOL technique C283500100040 by bombarding thick ZrC and graphite targets with 55 C283500100041 muA 500 MeV protons from the TRIUMF cyclotron. 7Li C283500100042 and 7Be were extracted from the target through a C283500100043 high-resolution mass separator, and the beryllium C283500100044 ionization was enhanced using the TRIUMF Resonant C283500100045 Ionization Laser Ion Source. After the ion source, C283500100046 the beam was transported through the ISAC C283500100047 high-resolution mass separator and then accelerated C283500100048 through the ISAC-I radio frequency quadrupole and C283500100049 drift-tube linac to final energy.
