Temperature Sensors

We utilize two types of the temperature sensors;

  • Vishay chip resistor: two wires (VI+ & VI-) per sensor
  • Cernox sensor: four wires (V+, I+, V- & I-) per sensor

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

  • These seven sensors are read out by one of LakeShore 218 through one Fischer connector (?? pins) at the insert side and two D25 connectors at the LakeShore 218 side.
  • The readout cable is of 16 conductors at min (2 wires * 6 sensors + 4 wires * 1 sensor).
  • A 24-conductor cable is in place, which goes through the east penetration.
    • The D25 and Fischer connectors are configured for "4 wires * 6 sensors".  Thus they have to be re-configured.
  • A 26-conductor cable will be placed for spare.
