ALICE (A Large Ion Collider Experiment) is a general purpose heavy-ion detector at the CERN LHC, addressing the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions.
ALICE has been recording physics data since the first proton-proton collisions at LHC as reference for the heavy-ion programme and to address physics topics for which it is complementary...

The performance of the CMS detector during the first operation with beam from the LHC is reviewed. The talk will discuss the overall performance of the CMS detector with some emphasis on operational aspects related to electronics

The LHC 7TeV Physics programme started at the end of March 2010. This talk highlights the experiences of running the LHCb detector with early pp-collisions from the LHC. An overview of the operation of the detector with the first 100nb^-1 will be given, and the challenge of running the detector smoothly in the initial data taking stages. Focus will be given to the performance of the hardware...

The ATLAS Level-1 trigger system is responsible for reducing the anticipated LHC collision rate from 40 MHz to less than 100 kHz. This Level-1 selection identifies jets, electrons/photons and muons, with additional triggers for missing and total energy. These inputs are used by the Level-1 Central Trigger to form a Level-1 Accept decision. This decision, along with clock and summary...

We report on the first operations of the CMS Regional Calorimeter Trigger (RCT) with collisions. Many first physics analyses at CMS have used calorimeter triggers. The RCT receives 8 bit energies and a data quality bit from the HCAL and ECAL Trigger Primitive Generators (TPGs) and sends it to the Global Calorimeter Trigger (GCT) after processing. The RCT hardware consists of 1 clock...

The ATLAS Transition Radiation Tracker (TRT) is the outermost of the three sub-systems of the ATLAS Inner Detector containing close to 350,000 thin-wall drift tubes (straws) operated with a Xenon-based gas mixture. The characteristics of the TRT data acquisition are exemplified by the front end electronics. These consist of separate analog and digital ASICS, the ASDBLR and DTMROC. The...

The acquisition board is used as a readout board for the LHCb beam pickups in order to continuously monitor the bunch intensities and the phase of the bunches of protons with respect to the LHC bunch clock, and as a high-speed and high-sensitivity readout system for a scintillator background monitor which records fast beam losses with time information.
In this paper we will describe its...
