Commissioning status of the chopper system for the Max IV injector

• The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation, and a short-pulse-facility (SPF). The two rings are designed for 3 GeV and 1.5 GeV, respectively, where the initial beam commissioning of the former has recently been completed, and commissioning of the latter was started in September 2016. Both rings will be operating with top-up injections delivered by a full-energy injector. In order to reduce losses of high-energy electrons along the injector and in the rings during injection, only electrons that are within a time structure where they can be accumulated in the ring buckets are accelerated. Electrons outside this time structure are dumped before they reach the first LINAC structure by a chopper system. The performance of the chopper system during commissioning of the 3 GeV ring is presented in this paper.
