Magnet current data acquisition using DCCTs and DVMs

Equipment for magnet current measurements at the dipole series test facility is located in room SH5/2.001 (magnet power supply room).

Two magnet power suppplies and accordingly two magnet current measurement devices (DCCTs) are available, providing a voltage of +10Vdc @ 20kA each to the input of a digital voltmeter (DVM).

  1. LAN-Switch at network socket SH1A01 (supported by R. Vincelli, CSCO 2345)
    • Dedicated connector: 01X05 (marked with blue dot)
    • IP-Name: NWE41Em
  2. GPIB-Controller type NI-GPIB-ENET/1000
    • MAC: 00-80-2F-21-A8-A7
    • IP:
    • IP-Name: MTDEV008
    • Default Hostname: NIENET1A98F55
  3. Two DVMs type Keysight 3458A; 8.5digit; accessible via GPIB
    1. QuD1 +3, Serial No. MY45052070; GPIB-Addr.: 13, dedicated to DCCT1 (Feedbox 1 and 3)
    2. QuD2 +4, Serial No. MY45051842; GPIB-Addr.: 24, dedicated to DCCT2 (Feedbox 2 and 4)
Each DVM in SH5 is connected to a trigger line (SYNC, Coax RG58, available at each QuD -cabinet) for synchronization of measurements with another DVM at the testbenches in SH2. The present Y-configuration of SYNC cables may electrically not be perfect but was the fastest solution before closing the fire safety flap for cables between buildings SH2 and SH5.

Convention: DCCT-DVM is trigger slave (Input - EXT. TRIG), testbench-DVM is trigger master (Output - EXT. OUT).
