Modeling and Commissioning of a Cold Compressor String for the Superfluid Cryogenic Plant at Fermilab's Cryo-module Test Facility
/ Ueresin, C (Linde Kryotechnik, Pfungen) ; Decker, L (Linde Kryotechnik, Pfungen) ; Treite, P (Linde Kryotechnik, Pfungen)
In 2011, Linde Cryogenics, a division of Linde Process Plants, Tulsa, Oklahoma, was awarded the contract to deliver a 500 W at 2 K superfluid cryogenic plant to Fermi National Accelerator Laboratory (FNAL) in Batavia, Illinois, USA. This system includes a cold compressor string with three centrifugal compressors and a vacuum pump skid with five volumetric pumps in parallel used to pump down helium to its saturation pressure corresponding to 2 K.

Detailed Magnetic Model Simulations of the H− Injection Chicane Magnets for the CERN PS Booster Upgrade, including Eddy Currents, and Influence on Beam Dynamics
/ Benedetto, Elena (CERN) ; Balhan, Bruno (CERN) ; Borburgh, Jan (CERN) ; Carli, Christian (CERN) ; Martini, Michel (CERN) ; Forte, Vincenzo (Clermont-Ferrand U. ; CERN)
The CERN PS Booster will be upgraded with an H^{−} injection system. The chicane magnets for the injection bump ramp-down in 5 ms and generate eddy currents in the inconel vacuum chamber which perturb the homogeneity of the magnetic field. [...]
