SPS 800 MHz power

All eight individual IOT transmitters validated

Line #1 tested up to200 kW CW on load

New cavity controllers ready

Still very bad news from ElectrosysSecond Circulator and no spare at all delivered

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
