We plan to arrange a set of sensors per insert as follows;

  • Top cup:       Chip, Chip, Chip
  • Center cup:  None
  • Bottom cup: Chip, Chip, Chip
  • Nose:            Cernox

Readout

Target Insert: 

The target insert has three PTFE target cups, and each cup is housed with three NMR coils. These NMR coils are started from the top of the target insert, with the SMA connectors routed from inside the shell of the insert and end on the target cups. The top and bottom cups are housed in three-chip resistors, and the Cernox and the middle cup do not have any sensors.  These sensors are reading through the LakeShore 218 via the fisher connector housed at the top of the insert. The fisher (female) connector is attached through the small wires routed inside the insert shell and connected to the sensors on the target cups. To read these sensors, a cable is required that has a fisher (male) connector, and the other end has two DB 25 (male) connectors to connect to the rear panel on the lakeshore DB 25 (female) connectors. For this purpose, the fisher (female) on the insert and the fisher (male) on the cable should be on the same pin configuration. The pin assignment for the target is explained below:

  • These eight These seven sensors are read out by one of LakeShore 218 through
    • One Fischer connector (27 pins) at the insert side and

    • Two D25 (female) connectors at the LakeShore 218 side.

  • The readout cable is of comprises 20 conductors at min minimum (2 wires * 6 sensors + 4 wires * 2 sensor).A 26-conductor cable is in place, which goes through the east penetration.
    The D25 and Fischer connectors are configured for "2 wires * 6 sensors (resistorschip resistors (12 wires) + 4 wires * 2 sensors Cernox (cernox8 wires))" Thus they have to be re-configured.
  • The new pin assignment is given below.

  • A 26-conductor cable will be placed for spare.
