Abstract
The critical part of the normal conducting (NC) positron preaccelerator (PPA) at the ILC positron source (PS) are capture sections that should operate with an accelerating gradient of up to 15 MV/m in combination with long RF pulse (∼1 ms). Developed at the Institute of Nuclear Research (INR) and now being constructed at DESY, the CDS booster cavity for the Photo Injector Test facility, DESY, Zeuthen, will operate under the same conditions and is a full-scale, high-RF-power prototype of the PS capture cavities. Cavity construction status and results of cavity tuning at a low RF level are presented. Other features of the standing wave cavities for the PPA, such as RF pulsed heating, advanced cooling, and beam loading, are discussed.
