Vibration Studies of the Stanford Linear Accelerator†
Vibration measurements of the linear accelerator structures in the SLC linac show a 1 micron rms vertical motion. This motion reduces to 0.2 micron rms motion when the cooling water to the accelerator structures is turned off. The quadrupoles have 250 nanometer rms vertical motion with the accelerator structure cooling water on and 60 nanometer motion with it off. These results together with me...
متن کاملUpgrade Issues for the Cern Accelerator Complex
The Large Hadron Collider (LHC) at CERN is at a very advanced stage of hardware commissioning and the first beam collisions in the experiments are expected during the year 2008. In line with the recommendations issued in 2006 by the European Strategy Group for Particle Physics, work has now started for maximizing the physics reach of the LHC and for preparing for other foreseeable needs. Beyond...
متن کاملGround Motion and Vibration Issues for Accelerators
Ground motion and vibration can be a limiting factor in the performance of future colliders, in particular linear colliders and large hadron colliders. Investigations of ground motion have been carried out around the world for several decades. In this review, after brief discussion of ground motion requirements for NLC, TESLA and VLHC, the results of recent investigations of ground motion are p...
متن کاملR&d Vacuum Issues of the Future Gsi Accelerator Facilities
The new GSI accelerator facilities (FAIR project) are planned to deliver heavy ion beams of increased energy and highest intensity [1]. Whereas the energy is planned to be increased roughly by a factor of 30, the ion beam intensities are planned to be enlarged by three orders of magnitude. To achieve highest beam intensities, medium charged heavy ions (e.g. U) are accelerated. Since the ionizat...
متن کاملAccelerator Physics Issues for Future Electron-ion Colliders
Interest continues to grow in the physics of collisions between electrons and heavy ions, and between polarized electrons and polarized protons [1, 2, 3]. Table 1 compares the parameters of some machines under discussion. DESY has begun to explore the possibility of upgrading the existing HERA-p ring to store heavy ions, in order to collide them with electrons (or positrons) in the HERA-e ring,...
