Bambino: a segmented silicon detector system for TIGRESS
Bambino is a charge-particle detector system with sufficient energy and position resolutions for the differentiation between projectile-like and target-like particles and for the needed Doppler-shift corrections to the detected {gamma} rays in TIGRESS. It consists of two annular silicon detectors having an active inner diameter of 22 mm and outer diameter of 70 mm and a thickness about 150 {micro}m. They are placed 3.0 cm from the target and provide solid-angle coverage of 1.15{pi} sr. Each has 24 sectors in {theta} for the angle coverage between 20.1{sup o} and 49.4{sup o} and between 130.6{sup o} to 159.9{sup o} and has 16 sectors in {phi} for 2{pi} coverage. Three of those detectors and the matching preamplifiers, cables etc were ordered and received in 2005 at a cost about $50k funded by DOE/OS. The system was undergoing various tests at both LLNL and TRIUMF in the second quarter of 2006 and was successfully integrated into TIGRESS for the commission run in July/August 2006. A side-accessible spherical target chamber, used in the commission run, was designed and built in Rochester in the second quarter of 2006 to accommodate this detector system at a cost about $28k funded by NSF and AFOSR.
