General Instrumentation Information • • CERNOX 1050 -SD RTD (300 K to 1. 6 K). CLTS (Cryogenic Linear Temperature Sensor) (300 K to 4 K). PT 1000 RTD (450 K to 40 K). Liquid Helium Level Sensor: 2 K type, cold feedthrough. SC Quad: Lead wire feedthrough LHC type or similar. Piezo sense and actuator: Noliac, tested in HTC-I, II, and III. Tuner Motor: Cold, tested in HTC-I, II, and III. Heaters: • • One heater per helium vessel mounted on 2 K 2 Phase Line. Two heaters per HOM load, 200 W each. • Vacuum Monitoring and Control: Open for discussion. • RF cable: Semi-rigid or Flexible coax. 9/5/2021 Peter Quigley, MLC Design Review
