The SNS insulating vacuum design for the superconducting linac

Content Provider	IEEE Xplore Digital Library
Author	Williams, D. Geng, X. Ladd, P.
Copyright Year	2007
Abstract	The superconducting linac of the spallation neutron source (SNS) has 23 cryomodules each of which incorporate either 3 or 4 niobium cavities. These cavities are submerged in a bath of liquid helium and maintained at an operating temperature of ~ 2 K. This bath is surrounded by heat shields and a multilayer blanket within the cryomodule shell. The pressure in this area needs to be maintained at <5e-5 torr to limit heat leak due to gas convection. Some cryomodules have developed helium leaks into this vacuum cavity and now need to be actively pumped. This paper provides an overview of the insulating vacuum system (IVS) that has been installed for this purpose.
