We discuss the status of a cryogenic dark matter search beginning operation in the Stanford Underground Facility. The detectors will be cooled in a specially designed cryostat connected to a modified side access Oxford 400 dilution refrigerator. We d

Design of the Cryopumping Vacuum System for ESCAR

Autor: R. C. Wolgast

Publikováno v: IEEE Transactions on Nuclear Science. 22:1496-1499

ESCAR is an experimental superconducting accelerating and storage ring for protons. Scattering collisions with residual gas degrades the quality of proton beams that are stored for long time periods. The loss of quality will be small if the average g

Vacuum Cryopumping a Heavy Ion Source in a High Voltage Terminal

Autor: R. C. Wolgast

Publikováno v: IEEE Transactions on Nuclear Science. 18:699-702

Two coldfingers differentially cryopump the heavy ion source of the SuperHilac 3-MV injector. One coldfinger near the source freezes most of the source gas load and provides adequate clean vacuum for source operation. The second coldfinger near the b

An eight-pancake Nb-Ti dipole magnet, with bent up ends, called D-108B has been built and tested. This magnet is a Nb-Ti version of a Nb/sub 3/Sn magnet designed to produce a 10-tesla dipole field in a 40 mm diameter aperture. The pancack design is u

The Omnitron (Fig. 1) is a synchrotron (120 ft. diam) accelerator with a concentric storage ring (130 ft. diam) that will deliver beams of light and/or heavy ions at different energies and currents. Storage of heavy ions in a high-charge state for 25
