Summary
The demonstrator is a prototype of the first section of
the proposed cw-LINAC@GSI, comprising a
superconducting CH-cavity embedded by two
superconducting solenoids. The sc CH-structure is
the key component and offers a variety of research
and development. The beam focusing solenoids
provide maximum fields of 9.3 T at an overall length
of 380 mm and a free beam aperture of 30 mm. The
magnetic induction of the fringe is minimized to 50
mT at the inner NbTi-surface of the neighboring
cavity. The fabrication of the key components is still in
progress and is near to completion. The cold
performance testing of the RF cavity is finished, the helium
jacket will be welded on soon. The first cold test of the cryostat @GSI was successful. The test environment is completely prepared.
Integration of the cryostat into the
beam line and commissioning of the RF elements will be performed
as next steps towards a complete testing of the
demonstrator.
