Oral

The electronics systems used to control, trigger, and acquire data from the four experiments at LHC are, for the field of High Energy Physics, of unprecedented level of complexity and sophistication. In the case of CMS, users are gaining access to the counting room (USC55) at a late stage with respect to the official LHC start-up date. Measures taken to reduce the time required between...

15. Installation and Commissioning of the On-Detector Electronics for the CMS Electromagnetic Crystal Calorimeter

Cristina Biino (INFN - sezione di Torino)

26/09/2006, 14:40

Oral

The CMS electromagnetic calorimeter is composed of 76,000 PbWO_4 scintillating crystals. The scintillating light is captured by photo-detectors, amplified and digitized. The conversion is performed inside the detector volume and data are transported through optical fibers to the off-detector electronics. About 25,000 Printed Circuit Boards of 5 different types and...

17. Performance of CMS ECAL Very Front End Electronics

Alessandro Nardulli (Eidgenössische Technische Hochschule, ETH, Zurich, Switzerland)

26/09/2006, 15:05

Oral

We report the results of tests of 12800 Very Front End (VFE) readout cards for the barrel of the CMS electromagnetic calorimeter. A thorough test sequence was applied to each card including power-on test, burn-in and final detailed calibration. The results show excellent uniformity of the VFE cards. For instance the analogue, digital and buffer currents have average values of 1.59, 0.43...

87. FEC-CCS: A common Front-End Controller card for the CMS detector electronics.

Kostas Kloukinas (CERN)

Oral

The FEC-CCS is a custom made 9U VME64x card for the Off-Detector electronics of the CMS detectors. Special effort has been invested in the design of the card in order to make it compatible with the operational requirements of multiple CMS sub- detectors namely the Tracker, the ECAL Crystals and ECAL Preshower, the PIXELs, the RPCs and the TOTEM. This paper describes the design...
