| Abstract |
ALBA is a 3GeV synchrotron light source located in Barcelona and operating with users since May 2012. The RF system of the SR is composed of six cavities, each one powered by combining the power of two 80 kW IOTs through a Cavity Combiner (CaCo). At present, there are several RF interlocks per week. The redundancy given by the six cavities makes possible the survival of the beam after one of these trips. In these cases, the cavity has to be recovered with the circulating beam. An autorecovery process has been implemented in the digital LLRF system in order to recover the faulty RF plant after a trip. But these trips also create perturbations to the beam stability. In order to minimize the beam perturbations induced by these RF interlock, an additional feed-forward loop is being implemented. The functionally, main parameters and test results of these new algorithms will be presented.
