Recent helium shortages and helium price increases have lead to an increased emphasis being placed on conserving helium. The need to conserve helium must be balanced with need to maintain the high levels of purity necessary to prevent operational problems caused by contamination. Helium losses and contamination control are especially important for test stands that have cryogenic distribution...
Oak Ridge National Laboratory, through support of the US Department of Energy’s Office of Basic Energy Sciences, has begun applying machine learning methods to improve accelerator and target performance of the Spallation Neutron Source (SNS). One application of these methods is the control optimization and power upgrade of the Cryogenic Moderator System (CMS). To study such optimizations and...
The European Spallation Source ERIC (ESS) will provide long-pulsed cold and thermal neutron fluxes at very high brightness to the research community. At the ESS target, high energy spallation neutrons are produced by impinging a 5 MW proton beam on the high-Z material, tungsten. The proton beam is pulsed with a repetition of 14 Hz and a pulse length of 2.86 ms. The spallation neutrons are...
The cryogenic distribution system at FRIB is extensive, encompassing three Linac segments, fourteen experimental system superconducting magnets, cross-connect between FRIB and the reconfigured NSCL legacy system, and the A1900 magnets, as well as many other user experimental loads. The cool-down or warm-up of these transfer-lines is an inherently transient process and must be conducted at a...
Dalian Advanced Light source (DALS) test facility program will build four testbenches, a horizontal test bench (HTB) for module testing, a vertical test bench (VTB) for superconducting cavity testing, an injector test bench (ITB) for beam testing and a cryogenic test bench (CTB). The testbenches cooling are provided by a 370 W @ 2 K cryoplant. The simulation of the cryogenic system can play an...
