  5. General Instrumentation Information • 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.
