June 8: The evaporator is down due the chiller failure. We have found out the chiller pump is needed to be replaced. We are ordering the new part and will fix the issue as soon as possible.
June 10: The chiller pump was out of stock in market. We need to wait for delivery till earlier July …
June 23: We received the new water pump and started installing the replacement pump. Unfortunately, we accidentally overtightened one of the Swagelok tube fittings during our attempted repair and damaged it. We were purchasing new parts for repair.
July 8: Here is good news. The chiller issue has been solved. The Angstrom evaporator is fully operational now. We have tested the deposition process and confirmed that the instrument is on good status. Please go ahead to reserve the instrument time you need.
Sorry to have this long downtime.
