4 ATLAS ATLAS DCS B.Hallgren, CERN EP/ ATD ATLAS DCS Workshop 2-3 Oct 2000 4 Development of the ELMB is motivated by  Radiation Problems Total Ionising Dose TID CMOS MUX Non-Ionising Energy Loss NIEL Optocouplers Single Even Effects SEE Memory bit errors  Magnetic Field (1.5T to 0.1T)  Magnetic Field (1.5T to 0.1T) DC-DC converters  Access restriction - should work 24h and 365 days/year  I/O points distributed over the whole detector volume <100m  Standardised connections to the SCADA Hardware: CANbus / LAN Software: CANopen, OPC, TCP/IP

5 ATLAS ATLAS DCS B.Hallgren, CERN EP/ ATD ATLAS DCS Workshop 2-3 Oct 2000 5 and furthermore...  Reduced design effort by individual institutes  Common Open Embedded Software templates, libraries  Spares and maintence during the detector lifetime (15 years)  Low power consumption cables, local power supplies  Commercial low cost in ATLAS several thousands will be needed  Common effort People from many subdetectors involved in HW and SW.
