The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) has taken cosmic-ray and colliding-beam data in 2009 and will be in continuous data-taking mode beginning at the end of February 2010. CMS detects the interaction products of proton beams colliding at a rate of 40 MHz. It uses a two-level trigger system to flag interesting events and reduce the event rate to a lower level,...
We developed a cost-effective SPECT scanner prototype (rSPECT) for in vivo imaging of rodents based on small-area gamma cameras. Each detector consists of a position-sensitive photomultiplier tube (PS-PMT) coupled to a 30 x 30 Nal(Tl) scintillator array and electronics attached to the PS-PMT sockets for adapting the detector signals to an in-house developed data acquisition system. The detector components...
