New test facility for SAT of SIS100 quadrupole doublet modules
Enrico Leo
The SIS100 synchrotron is presently under construction, and it will be part of the FAIR particle
accelerator facility at GSI-Darmstadt. The bending, focusing, as well as high order corrections of the
ion beam is demanded to superconducting magnets (dipoles, quadrupoles and correctors).
Quadrupoles and correctors are integrated in modules, together with temperature sensors, vacuum
gauges and beam diagnostic systems. To ensure the quality standard, after the warm factory
acceptance test, also cryogenic tests on the modules have to be carried out before installation in the
SIS100 tunnel. Following a MoU between GSI and INFN, a new test facility for site acceptance test
on quadrupole doublets modules (QDM) has been set up in Salerno. The test facility has been
designed to fulfill the requirements of the GSI test protocol. The protocol foresees a full
characterization of the QDM going through electrical tests, sensor and beam diagnostic integrity and
functionality, heat load measurements, as well as vacuum quality. All of these tests have to be carried
out at different conditions: room temperature/pressure, under vacuum from room temperature to 4.5K
and at room temperature/pressure again. The design and commissioning of the test facility in Salerno
will be presented together with preliminary results obtained during the first cooldown of the prototype
superconducting modules (FoS).
