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...

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...

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...

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...

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...
