90. Development and Commissioning of the CMS Luminosity Monitor

Dr John Jones (Princeton University)

Oral

We discuss the development and commissioning of a luminosity monitor. It is based on hardware that provides real-time histograms of data from the forward hadronic (HF) calorimeters in CMS. Measuring the total energy deposition and occupancy in these detectors allows us to calculate the relative instantaneous luminosity of the collider on a bunch by bunch basis also useful for machine...

19. Time calibration of the LHCb Muon System

Caterina Deplano (INFN Cagliari)

Oral

The LHCb Muon System consists of about 122,000 readout channels. It plays a basic role in the first trigger level. The trigger requires 95% efficiency in Muon tracks detection. It is then necessary to reach a system time alignment at the level of about 2 ns. This alignment must be monitored against possible fluctuations due to changes in the detector operating conditions. We describe...

36. CMS DT Chambers Read-Out Electronics

Cristina Fernandez Bedoya (CIEMAT)

05/09/2007, 17:10

Oral

Being close to completion of CMS installation, the three levels of the final read-out system of the Drift Tube (DT) chambers is presented. Firstly, the Read Out Boards (ROB), responsible for time digitalization of the signals generated by a charged particle track. Secondly, the Read Out Server (ROS) boards receive data from 25 ROB channels through a 240 Mbps copper link and perform data...

45. CSC Data Acquisition System for CMS

Dr Jianhui Gu (The Ohio State University)

05/09/2007, 17:35

Oral

Details of the Cathode Strip Chamber (CSC) Data Acquisition (DAQ) system for the CMS experiment at the LHC will be described. The CSC system is large, consisting of 218K cathode channels and 183K anode channels. This leads to a substantial data rate of ~1.5GByte/s at LHC design luminosity (1034cm-2s-1) and the CMS first level trigger (L1A) rate of 100KHz. The DAQ system consists...

44. The 1st Result of Global Commissioning of the ATLAS Endcap Muon Trigger System in ATLAS Cavern

Dr Takuya Sugimoto (Nagoya University)

05/09/2007, 18:00

Oral

We will report on the ATLAS commissioning run from the view point of the Thin Gap Chamber (TGC), which is the ATLAS end cap muon trigger detector. So far, a half of TGC chambers with on-detector electronics have been already installed to the ATLAS cavern. To integrate all sub-detectors before the physics run starting from early 2008, the global commissioning run together with other...
