86. The Front-End Electronics System for the CMS Electromagnetic Calorimeter

Mrs Nadia Pastrone (I.N.F.N. Torino)

15/09/2005, 14:00

Oral

CMS designed an high precision electromagnetic calorimeter, to be operated reliably in the high radiation environment of the CERN Large Hadron Collider (LHC), inside the 4 T magnetic field. Innovative solutions were developed to place the front-end electronics within the detector with the advantage of minimizing external noise, while reducing the number of optical links to send data...

51. Installation and Test of the CMS Crystal Calorimeter Electronics

Mr Werner Lustermann (Eidgenoessische Technische Hochschule, ETH Zurich, Switzerland)

15/09/2005, 14:25

Oral

The CMS Electromagnetic Calorimeter consists of roughly 76000 lead tungstate crystals. Nearly 25000 Printed Circuit Boards of 5 different types and about 5500 Gigabit Optical Links are used to process the signals of the photo-detectors and to send the resulting data to the off- detector electronics. The integration of this electronics together with its cooling system, mechanical...

24. CMS ECAL Front-End boards: the XFEST project

Caroline Collard (LLR Ecole Polytechnique)

15/09/2005, 14:50

Oral

The Front-End (FE) boards are part of the on-detector electronics system of the CMS electromagnetic calorimeter ECAL. Their numerical functionalities and properties are tested by a dedicated test bench located at Laboratoire Leprince-Ringuet, prior to the board integration in the CMS detector at CERN. XFEST, acronym for eXtended Front-End System Test, is designed to perform tests...

92. The Readout, Fast Control and Powering Architecture for the CMS Preshower

Mr Wojciech Bialas (CERN)

15/09/2005, 15:15

Oral

The CMS Preshower detector (ES) comprises ondetector and offdetector components of the readout and control system, as well as the powering system and optical links. The fast control system is largely built around the one originally conceived for the CMS Tracker (FEC, DOH, CCU etc.) whilst the readout part profits from developments made for the CMS ECAL (DCC, GOH, AD41240). There are two...

133. Characterization and production testing of a quad 12 bit 40 Ms/sec A/D converter with automatic digital range selection for calorimetry.

Dr Kostas Kloukinas (CERN)

15/09/2005, 15:40

Production, Testing, Quality Assurance and Reliability

Oral

The AD41240 is a custom made 12-bit 40 MSPS, quad-channel, radiation tolerant analog- to-digital converter for the front-end readout electronics of the CMS ECAL and Preshower detectors. The A/D converter features a special digital circuitry to allow automatic selection of gain ranges when it is used with a multi gain pre-amplifier. This paper describes the design architecture of the A/D...
