3. PTF Overview 2001: Planning started
2004: Installation complete and cryoplant running
2005: Feedboxes and universal cryostat installed
2006: complete cryo infrastructure in operation, beginning of normal operation (means magnet and component testing)
2006: Busbar and heat exchanger Tests, first model magnet (SIS overcritical operation with 60g/s)
2007: Anticryostat, first SIS100 model
SIS100 tests (including vacuum camber tests with and without magnet)
2010: Upgrade of the PTF (Shields for the Feedboxes; Cool down return line for independent operation,…)
2012: Upgrade for the SIS100 one layer pre series magnet (new current leads, kA power supply,…)

to find X=1 at coil outlet.
Assumption: all pressure drop
takes place only in the coil.

Study of a 14 kA-HTS current lead for SIS100
In order to operate the new single layer pre series dipole at the PTF we placed a
call for tender for 2 pairs of new HTS current leads.
These current leads are designed for the SIS100 bus bars so we get rid of the
present used adaptor, which adapts the Rutherford bus bars to the SIS100 ones.

10. Planned Series Test Facility (STF) for testing the SIS100
Dipole series and to enable a string installation...
...at a given location at GSI
...taking into account later use of the cryo infrastructure for the
planned sc-cw-linac at the same place

Planned job-site

up within this year.

12. Stripper Hall Given area is about 750 m²
in order to have as much testing
area as possible all technical infrastructure (including cryogenics)
will be placed in a separate technical extension.
So only the Feedboxes and transfer lines
will be in the hall. There will be enough
space to install at least 4 test benches
It´s also possible to install a string,
while suspending one test bench
For later install of sl-cw-linac, two
test benches have to be removed,
but two benches will be still available

13. STF annex building 1. level For most of the technical infrastructure
an annex building is in the planning phase:
15,6 x 19,8 m
9,30 m height
2 levels
needed cooling water capacity about 1,1 MW
compressor
ORS/GMP
cold box
switchgear
transformers
distribution box
main low voltage
feed-in
power supplies

14. Size of the cryoplant
2009 we made a request of quotation for a cryo plat of 900 4,5K
based on a planning of 1-2 test benches and a string (later sc-cw-linac [400 @ 4,5 K])
Required cooling power for 3-4 test benches: ,5 K
MAC advise 2011: K
Cryo plants above 900 W are not "standardized"
