The European XFEL (EuXFEL) is a 3.4 km long free electron laser that started commissioning in 2016. The machine can be divided into the superconducting LINAC with a length of 1.7 km and the following SASE sections. The latter sections use the accelerated electron beam with energies up to 17.5 GeV to generate 27,000 ultra-short flashes per second with a wavelength of 0.05 nm to 4.7 nm. These...
The European XFEL is a hard X-ray free-electron laser (FEL) with MHz repetition rate, based on a high-electron-energy superconducting linear accelerator. Located in Schenefeld, near Hamburg, Germany, the facility started operation in April 2017 and now provides extremely intense X-ray beam pulses to seven scientific instruments, up to three of them simultaneously by means of a multiplexed...
The vacuum system of the 3 GeV storage ring at MAX IV laboratory is based on a fully NEG (Non-evaporable Getter) coated, extruded copper pipe (22 mm inside diameter) that also serves as a distributed absorber intercepting synchrotron light. The ring has been in operation since the end of 2015 and performs very well. This presentation is summarizing the design and performance of the 3 GeV storage ring.
PETRA III is a third generation synchrotron light source situated at DESY in Hamburg, Germany. Since its commissioning in 2009 and extension in 2015, the 2.3 km long storage ring has been the basis of one of the world’s brightest light sources of its kind, and it is continuing to do so with respect to its future upgrade to PETRA IV. Throughout the years in operation, a lot of experience was...
FRIB approaches 2 years of successful operation of its Advanced Rare Isotope Separator (ARIS). This presentation reports on the experience gained by the FRIB Vacuum Operation Group in commissioning, operation, maintenance, troubleshooting, and repair of the vacuum systems of ARIS.
This presentation reports the improved vacuum system for the high-power beam operation in the rapid cycling synchrotron (RCS) from two perspectives: (1) Improved turbo molecular pump (TMP) system to prevent the failure caused by the high-intensity beam loss and (2) establishment of the pressure runaway suppression method through an understanding of the dynamic pressure mechanism. We describe...
The 3 GeV rapid cycling synchrotron (RCS) of J-PARC delivers a 1 MW proton beam. The RCS vacuum system has two main characteristics: turbomolecular pumps as the main evacuation and 200-400 mm large aperture, 1-3 m long alumina pipes. To realize the high intensity beam operation, the RCS beam and the beam pipes are thick for reducing space-charge force, and the extraction kicker magnets having...
