Pulsed RF control for the P-linac test stand at fair

The p-Linac will be a dedicated proton injector for antiproton production at FAIR. It will provide a 70 MeV, 70 mA pulsed proton beam with a duty cycle of about 10 -4 . The RF of the normal conducting CH cavities will be pulsed, too. In order to test operation of these cavities a test stand is under construction at GSI. The RF control hardware and software for the test stand has been developed at TU Darmstadt. It is based on the digital low level RF control system used at the S-DALINAC. Hardware and software had to be customized in order to achieve pulsed operation within the given limits. These customizations along with measurements in pulsed operation will be presented.
