Description
• Test enclosure – Assume this will be a Faraday cage, cold test box and light tight box.
• Location of test enclosure inside clean room. Proximity to cryostat.
• How it is opened and closed around the APA.
• Need of temperature, humidity sensor inside Faraday cage to measure dew point, line for dry air. Assume there will be dry air purge before cooldown to prevent frost on warmup.
• How to bring gas Nitrogen inside clean room? Assume cold Nitrogen gas will be used for cooldown. Rate of cooldown and warmup and how to control.
