Hees, Wolfgang LU ; Weisend, John LU ; Wang, Xilong LU and Köttig, Torsten LU (2014) Joint Conference of the Transactions of the Cryogenic Engineering Conference (CEC) / Transactions of the International Cryogenic Materials Conference In Advances in Cryogenic Engineering: Transactions of the Cryogenic Engineering Conference - CEC (AIP Conference Proceedings) 1573. p.655-658
Abstract
The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world's most powerful neutron source to be built in Lund, Sweden. The ESS will use a linear accelerator which will deliver protons with 5 MW of power to the target at 2.5 GeV with a nominal current of 50 mA. The superconducting part of the linac consists of over 150 niobium cavities cooled with superfluid helium at 2 K. A dedicated cryoplant will supply the cryomodules with single phase helium through an external cryogenic transfer line. The elliptical cavity cryomodules will undergo their site acceptance tests at the ESS cryomodule test stand in Lund. This test stand will use a 4.5 K cryoplant and warm... (More)

This test stand will use a 4.5 K cryoplant and warm sub-atmospheric compression to supply the 2 K helium. We will show the requirements for the test stand, a layout proposal and discuss the factors determining the required cryogenic capacity, test sequence and schedule. (Less)
