10/10/2015Peter Quigley, MLC Design Review CERNOX 1050-SD RTD (300K to 1.6K). CLTS (Cryogenic Linear Temperature Sensor) (300K to 4K). PT1000 RTD (450K to 40K). Liquid Helium Level Sensor: 2K 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 2K 2Phase Line. Two heaters per HOM load, 200W each. Vacuum Monitoring and Control: Open for discussion. RF cable: Semi-rigid or Flexible coax. General Instrumentation Information
