A controls issue with IOS:BIAS was found yesterday. Controls people resolved it today. MWS source was switched over and prepared for Rb beam. Leakchecking done: tight. Source should pump for a little while longer before energizing. At present, leak detector is attached to the IOS roughing line.

Later... Noticed that MCIS:TP2 was tripped off. After a couple of tries, it restarted okay. Hmm...
