Description
The first part will review the RF setting-up and operation in 2010: From the initial RF noise concerns (April), to the need for longitudinal blow-up with the nominal bunch intensity (May), then the problems to fill the machine when increasing the number of injections (dump triggered by secondary radiation related to capture losses). The statistics on RF fault and their cure will also be presented.
The second part concentrates on the higher intensity and energy operation foreseen for 2011. We will discuss the improvements expected from the Longitudinal damper and the benefits and side-effects from the 1-Turn feedback . The issue of surviving a klystron trip during physics will be studied, using both modeling and observations in 2010. Finally the settings proposed for klystrons and cavities (High Voltage, cathode current and Loaded Q) will be presented.
