• 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.
