SPS 800 MHz powerMoved circulator toline #2
Line #2 tested up to200 kW CW on load
Completed the RF conditioning up to180 kW CW on cavity #2Yesterday
Just started the RF conditioning on cavity #1 (without circulator ! So it will be slow as we will be very careful)

CavitiesAntennas have been added on both cavities
Combiner is still to be provided (LLRF)
Two old filters are overheating (has probably been always the case, discovered while checking the antennas)
We added a heat cooler
