The lid for sample dewar #1 stopped heating and was taken out of service. Troubleshooting discovered a bad thermocouple in the lid. There are two thermocouples installed as redundancy but the good one was apparently not making contact to the connector. The connector has been fixed so that the good thermocouple is working. Lid will be tested when time allows. Replacement of the bad thermocouple in the lid assembly will have to be done by Rigaku when time allows. - EZ
