Xbox2. Currently at 40MW, 100ns pulse length. 

PAA comments on interlock due to reflected power from load (PERB), but no vacuum events. LM comments that log detectors have a screw to fix the potentiometer (hardware detector). Maybe it needs to be adjusted. MV comments it can be calibrated. 

 

XBox3 HEK. We changed klystron from mod B to mod A, to see if it will work. Still trying to determine why we don't have enough output power from klystron. 

IS suggest putting more filters (3 if we have). AG comments that in that case, we will even have less power (not more)

WW asks if its same perveance. IS by design, yes, it's same cathode. PAA haven't been able to confirm (due to calibration of CVD, and calorimetry missing some degrees). 

Melboxes update. MV asks PAA to contact Ben for admin password. 

OB asks about BOC test. AG says we still have no gasket, and in any case, we need first to finish conditioning of structure.
