The Data Acquisition (DAQ) of the CMS Experiment [1] is composed by O(10000) network objects spread in O(1000) nodes, most of them based on commodity PCs, connected to a very efficient Local Area Network. The DAQ complex (both hardware and software) must be controlled in order to synchronize all the objects to perform in the proper sequence the needed(More)
The data collected with the DELPHI detector at high energies (130-172 GeV) during LEP operation in 1995 and 1996, have been used to determine the hadronic and leptonic cross sections and leptonic forward{backward asymmetries. The results of the S-matrix ts to these data and to the data collected previously at the energies near the Z 0 resonance peak (88-93(More)
The DAQ system of the CMS experiment at CERN collects data from more than 600 custom detector Front-End Drivers (FEDs). During 2013 and 2014 the CMS DAQ system will undergo a major upgrade to address the obsolescence of current hardware and the requirements posed by the upgrade of the LHC accelerator and various detector components. For a loss-less data(More)
The Compact Muon Solenoid (CMS) research group at CERN is responsible for one of the four experiments in the Large Hadron Collider in Geneva. The software, controlling this experiment, consists of 20,000 finite state machines, which are strictly hierarchically organised. The complexity of the software has grown out of hand and it is not predictable anymore.(More)
The high level Detector Control System (DCS) of the CMS experiment is modelled using Finite State Machines (FSM), which cover the control application behaviours of all the sub-detectors and support services. The Joint Controls Project (JCOP) at CERN has chosen the SMI++ framework for this purpose. Based on this framework, the functionality and behaviour of(More)

The Run Control System of the Compact Muon Solenoid (CMS) experiment at CERN’s new Large Hadron Collider (LHC) controls the sub-detector and central data acquisition systems and the highlevel trigger farm of the experiment. It manages around 10000 applications that control custom hardware or handle the event building and the high-level trigger processing.(More)
The CMS experiment at the CERN Large Hadron Collider is currently being commissioned and is scheduled to collect the first pp collision data in 2008. CMS features a two-level trigger system. The Level-1 trigger, based on custom hardware, is designed to reduce the collision rate of 40 MHz to approximately 100 kHz. Data for events accepted by the Level1(More)
