Hi, All,
The Evaporator was down in the weekend of Aug 31 due to the CTI 8200 compressor failure. We tried to purchase a new CTI compressor, but the lead time is 8 weeks that is too long. We contacted several compressor vendors asking for the quotes for a new compressor and/or refurbished one. Finally we decided to purchase a M125 compressor from Trillium. The order was placed on today, 9/11.
We found that the cryopump has an issue with He decontamination and needs to be replaced. The order for a new pump is placed on Oct. 1 and will arrive in a few days.
The new compressor will arrive on Oct. 2.
Users could expect that the Evaporator will be up running in the earlier next week, 7th of Oct.
The new compressor and cryopump were installed. The system was regenerated successfully. The Evaporator was up running on Oct. 11th, Friday.
Feel free to let me know if you have questions.
Thanks,
Qiyin
