Last week : Po for CRIS 

Setup ready and stable until Friday very early morning when the AC turned off because of the chiller failure. 
All lasers were put on « saving mode » to protect for high humidity. 
Around 3pm the temperature was stable again and humanly adequate. Lasers were reoptimized and the Po ionization could proceed at around 5pm. 
Lasers were stable until the run was stopped on Sunday.
