First lasing of the mid-infrared free-electron laser at ELBE was achieved on May 7, 2004. The Radiation Source ELBE at the Forschungszentrum Rossendorf in Dresden is currently under transition from commissioning to regular user operation. Presently the electron linac produces an up to 18 MeV, 1 mA (cw) electron beam which is alotted to generate various kinds of secondary radiation. After the su...
A prompt report for the commissioning run of the longbaseline neutrino oscillation experiments will be presented. Improvement of the KEK-PS main ring has been performed for recent years in order to prepare the long-baseline neutrino oscillation experiment. Intensity upgrade studies and the hard ware improvements result in a factor of 50% increase in the beam intensity to 5-6 × 10 ppp up to now....
Volumetric-modulated arc therapy (VMAT) has been shown to be able to deliver plans equivalent to intensity-modulated radiation therapy (IMRT) in a fraction of the treatment time. This improvement is important for patient immobilization/localization compliance due to comfort and treatment duration, as well as patient throughput. Previous authors have suggested commissioning methods for this moda...
The LHC operational cycle is comprised of several phases such as the ramp, the squeeze and stable beams. During the ramp and squeeze in particular, it has been observed that the behaviour of key LHC beam parameters such as tune, orbit and chromaticity is highly reproducible from fill to fill. To reduce the reliance on the crucial feedback systems, it was decided to perform fill-to-fill feedforw...
The neutrons for science facility (NFS), the first operational experimental area of new GANIL/SPIRAL-2 facility, received its beams in December 2019. Proton-induced reaction cross-sections as well neutron beam characteristics were measured during commissioning phases. results, showing features are presented here and compared with previously published data. physics cases accepted experiments well.
HITRAP is an ion trap facility which is designed for deceleration and cooling of highly charged ions produced by the GSI-accelerator facilities. The ions are decelerated in the ESR and then ejected at 4 MeV/u. Subsequently they are further decelerated by the HITRAP linac [1]. Since the HITRAP decelerator gets an ion bunch from the ESR every 50-60 seconds, it is necessary during linac commission...
