Charge |
1. Does the heater tape
and thermocouple selection and placement meet all performance
requirements?
2. Do the heater tapes and thermocouples satisfy envelope,
requirements? Are they compatible wit the cooling tubes,
magnetic loops, mounting hardware, insulation, etc? Can they be
readily installed.
3. Have potential
failure modes been adequately addressed in the design?
4. Is the design
documentation required to procure, fabricate, and install the parts
adequate? |

Summary of Results
|
Goranson presented the
status of the heater tape design. There were seven chits generated and
dispositioned at the review. The heater tape and thermocouple
selection and placement meet the performance requirements. The
heater tapes and thermocouples satisfy envelope requirements and are
compatible with the cooling tubes, magnetic loops, mounting hardware,
insulation. The design documentation required to procure,
fabricate, and install the parts was adequate. The chits
identified some issues with interface details with the cryostat
feed-thrus, power supply requirements, MTBF, protection for the heaters
and TC during installation, and a question of radiation resistance of
the heaters. This review was considered successful pending
resolution of the chits.
