Operation reports & Closure
- Daniel Valuch (CERN)
In past two years, we have experienced two serious failures of our SRF cavities. Cavity 2 developed a leak from the helium can into cavity UHV and the RF window assembly of cavity 4 failed after just 10 months’ operation. The UHV leak repair is on-going but the RF window was swapped with a spare in a clean room on site and cavity 4 has been subsequently tested to over 2 MV. The impact of...
PETRA has not the availability as expected and stated to the MAC in November 2015.
It is, with 95 %, not “state of the art” for 3rd generation synchrotrons.
That is why a ”PETRA III Availability Review” takes place in May 26-27, 2016.
We want to present the result of this review from the rf point of view.
A sophisticated power supply was developed, built and commissioned to operate the RF system of the Collector Ring, a storage ring of the future FAIR (Facility for Antiproton and Ion Research) complex. It supplies the power amplifier of RF: a total of 5 power supplies (anode, control grid, two screen grids, two filaments) and a controlled load.
The RF system will be operated in continuous...
