| Abstract: The detector control system (DCS) of CMS, one of the big future experiments at LHC, comprises two different classes of items to control: one is the "classical" slow control like HV, LV, gas, cooling, etc.. The second class of items is the control of downloading all necessary constants and programs to the front-ends and the control of calibration data-taking within the local DAQ of each subdetector. All four LHC experiments decided some years ago to try to do as much as possible together in building their respective DCS system. This was manifested in the creation of JCOP (joint controls project). The basic ideas of the common framework were first, to have a common platform for all controls within each experiment and secondly to use commercial components where ever possible for hard- and software in order to economise manpower for development. JCOP tried to follow these lines and already selected some industrial components for hard- and software. One of these items is a commercial SCADA (supervisory controls and data acquisition) system. This sophisticated software tool includes all the features of a supervisory system such as alarms, trending, security, etc.. It is object orientated and completely scalable up to the huge number of parameters which have to be controlled in this big new experiment. The presentation will describe in detail the tasks of DCS and the envisaged implementations including the SCADA system. |

| Brief Bio: I studied physics and mathematics at the University of Heidelberg analyzing for my diploma and Ph.D thesis fragmentation and B-decays within the ARGUS collaboration at DESY. After being a member of the ALEPH collaboration at LEP, I started, in 1992, to work for NA48 and ATLAS, first at the University of Siegen and then in1993 at CERN. Whilst a fellow and then a staff member at CERN, I was responsible, amongst other activities, for the digital read out of the LKr calorimeter of NA48 and was heavily involved in the epsilon'/epsilon analysis. In 1998 I was nominated as detector controls co-ordinator of the future CMS experiment at LHC. Web Sites: http://itcowww.cern.ch/ITCO/DCS-CMS/ http://itcowww.cern.ch/jcop/ |
