The electromagnetic calorimeter of the CMS experiment at CERN is an homogeneous calorimeter made of about 80000 Lead Tungstate crystals, that will start to operate at the LHC at the end of 2007. From June to November 2006, ten barrel Supermodules (1700 crystals each) were exposed to beam at CERN SPS, both in standalone and in association with portions of the Hadron Calorimeter. We present the description...
The ALICE trigger system consists of the Central Trigger Processor (CTP) and 24 Local Trigger Units (LTU) that act as a uniform interface to sub-detector front-end electronics. The CTP generates three levels of hierarchical hardware triggers - L0, L1 and L2. At any time, the 24 sub-detectors of the ALICE experiment are dynamically partitioned into up to 6 independent clusters. Trigger selection includes...
The DOslash experiment was upgraded in spring 2006 to harvest the full physics potential of the Tevatron accelerator at Fermi National Accelerator Laboratory, Batavia, Illinois, USA. It is expected that the peak luminosity delivered by the accelerator will increase to over 300 times 1030 cm-2s-1. One of the upgraded systems is the central track trigger (CTT). The CTT uses the central fiber tracker...
The ALICE trigger system is situated in the experimental cavern and has a centralized layout: the central trigger processor (CTP), the sub-detector interface (local trigger unit) and the TTC partitions are all installed in adjacent racks. The CTP generates three levels of hierarchical hardware triggers - LO, LI and L2. At any time, the 24 sub-detectors of the ALICE experiment are dynamically partitioned...
