MAX-lab is a national laboratory operated jointly by the Swedish Research Council and Lund University. Yearly more than 800 individual researchers use the laboratory to carry out experiments in many different areas. The MAX IV project which is the next generation synchrotron radiation facility in Sweden consisting of two synchrotron accelerators 3 and 1.5 GeV and one 3 GeV linear accelerator (linac) will replace the existing laboratory when finished.
The electrons will be produced in two electron guns and then accelerated in the 250 meter long linac to an energy of 3 GeV. Depending on which ring the electrons are being injected into they will be extracted from the linac at different points corresponding to the correct energy of the ring. The linac should also be used to produce short bunches for the short-pulse facility (spf).
The presentation will focus on the Max IV RF systems including accelerating structures, power sources and low level RF (LLRF) control and distribution networks in the linear accelerator and in both the 3 and 1.5 GeV storage rings. When the linac is used as spf the demands on RF phase and amplitude stability in the linac is high. How this is achieved will be shown.
