Taking part in ECAL Endcap installation with ETHZ

• Started with testing readout modules in ECAL Endcap DAQ system ( 7 Apr ~ 11 Apr, 2008 )
  • Single SC ( Super Cluster ) test by using 50 signal samples
  • How they affect by various powers ( dBm ) and frequencies ( 9kHz ~ 500 MHz )
    • dBm = 10 * log ( gain power / input power ) , the unit of power is WATT
    • the frequency of LHC is ~ 40 MHz

• Installing readout modules at Dee 1
  • VFE ( Very Front End ) Electronics
  • Low Voltage Regulators
