Halo Collimators a perfect example of highly configured vacuum solutions
The Linac Coherent Light Source at SLAC takes X-ray snapshots of atoms and molecules at work, revealing fundamental processes in materials, technology and living things. LCLS is an Office of Science User Facility operated for the U.S. Department of Energy by Stanford University. The LCLS is the world’s first hard X-ray free-electron laser. Its strobe-like pulses are just a few millionths of a billionth of a second long, and a billion times brighter than previous X-ray sources. Scientists use LCLS to take crisp pictures of atomic motions, watch chemical reactions unfold, probe the properties of materials and explore fundamental processes in living things. Its performance to date, over the first few years of operation, has already provided a breathtaking array of world-leading results, published in the most prestigious academic journals and has inspired other XFEL facilities to be commissioned around the world.
In January of 2017 Nor-Cal Products was awarded a DOE contract to manufacture and deliver 22 Halo Collimators to the SLAC National Accelerator Center
, for installation at LCLS-II. Since that time, Nor-Cal Products has successfully delivered a total of 25 Halo Collimators.
Adjustable-gap collimators are used to eliminate undesirable electrons in order to avoid excessive radiation due to beam loss in sensitive areas and to reduce activation of accelerator components. The halo collimator system consists of multiple sets of adjustable rectangular jaws strategically placed to make cuts in the six dimensional beam phase space while allowing the desired, much smaller beam to pass unaffected. The various wakefields of the collimators, including possible misalignments, are also assessed here to ensure there is no significant degradation of the beam brightness.
This is just one example of how Nor-Cal Products has aided in improving ultra-high vacuum system integrity. Nor-Cal Products continues to grow and expand our capabilities. In doing so, we’re proud to be contributing to the advancement of science. Please consider Nor-Cal Products when faced with a new or challenging project. Nor-Cal Products would welcome the opportunity to become a true partner in your next endeavor!
