	The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The two rings are designed for 1.5 GeV and 3 GeV, respectively, where the former is under construction, and the latter is undergoing beam commissioning. Both rings will be operating with top-up injections delivered by a full-energy injector that consists of 39 traveling-wave S-band LINAC structures. In order to reduce losses of high-energy electrons along the injector and in the rings during injection, only electrons that are within an allowed time structure are accelerated. This time structure depends on several parameters such as the available RF voltage and the radiation losses in the ring that is about to be injected, but also on the momentum acceptance of the transport lines in the injector. The electrons that are outside the allowed time structure are dumped when they have energies below 3 MeV by a chopper system that is located between a thermionic RF gun and the first LINAC structure. Basically, the chopper system consists of two planar striplines and a variable aperture, and the first stripline is fed with a superposed RF signal and the second one with HV pulses. The performance of the chopper system during commissioning of the 3 GeV ring is presented in this article.

The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The two rings are designed for 1.5 GeV and 3 GeV, respectively, where the former is under construction, and the latter is undergoing beam commissioning. Both rings will be operating with top-up injections delivered by a full-energy injector that consists of 39 traveling-wave S-band LINAC structures. In order to reduce losses of high-energy electrons along the injector and in the rings during injection, only electrons that are within an allowed time structure are accelerated. This time structure depends on several parameters such as the available RF voltage and the radiation losses in the ring that is about to be injected, but also on the momentum acceptance of the transport lines in the injector. The electrons that are outside the allowed time structure are dumped when they have energies below 3 MeV by a chopper system that is located between a thermionic RF gun and the first LINAC structure. Basically, the chopper system consists of two planar striplines and a variable aperture, and the first stripline is fed with a superposed RF signal and the second one with HV pulses.

The MAX IV linac is used both for injection into a 3 GeV storage ring, and as a high brightness driver for a Short Pulse Facility (SPF). The linac has also been deigned to handle the high demands of an FEL injector. The first phase of beam commissioning of the linac was completed and operations for ring and SPF injection has been ongoing for several months. In this paper we present the results from beam commissioning, injections to the storage ring and SPF operation.
