Thermosiphon Low Temperature Commissioning on Detector

Tuesday Jun 27, 2017, 4:00 PM → 5:30 PM Europe/Zurich

40/4-C01 (CERN)

Michele Battistin (CERN)

Discussion for the definition of the thermosiphon low temperature test on detector

4:00 PM → 4:05 PM Introduction

Speakers: Dave Robinson (University of Cambridge (GB)), Michele Battistin (CERN)

4:05 PM → 4:15 PM Presentation of the low temperature test plan

• Run on compressors
• Swap to TS at the same pressure (temperature)
• Reduction of the TS pressure
• Reduction of the BPR pressure (temperature to be defined with you – minimum value could be 1 bar(a) @ BPR -> probably -25°C on detector)
• Run on detector at low temperature for 1-2 hours
• Rise of the BPR pressure
• Rise of the TS pressure
• Swap from TS to compressors

Speaker: Martin Doubek (Czech Technical University (CZ))
