Status of HIPPI – Technical Info
- A negative point for the coordination between EU project: GSI has
chosen for the FAIR Linac the frequency of 324 MHz (Toshiba
klystrons), as RAL did already a year ago. Arguments: Toshiba is
becoming leader on the market (JPARC, China) + have a common
frequency with a possible UNILAC upgrade (324=3*108).
- CERN remains alone in the choice of 352 MHz for Linac4, imposed by
the available LEP klystrons (8 MEUR value for the project) and other
RF equipment and by the frequency of the IPHI RFQ.
- A common frequency would have allowed to gain more weight towards
the klystron manufacturers, via competition between Thales and
- The choice of 324 MHz gives a clear preference to a non-EU company
(Toshiba) and could definitely cut out of the market Thales.
8 CSC, 13.9.2006
Status of Linac4 & GSI FAIR linac
- Linac4 included in the Medium Term
Plan submitted to the Council at the
end of the year. Upon demand by R.
Aymar, minimum funding in 2007
(1.3 MCHF, but 6 additional posts).
Real funding from 2008, first
injections in PSB from 2011.
- Technical Design Report in
preparation (draft 15.10.06), big
step forward in the machine design.
- New options under consideration:
single frequency (352 MHz only), - GSI will start ordering a klystron
new position in an extension of the prototype already in 2006. The
Linac2 tunnel. accelerating cavities (CH) have
modified by adding a coupling cell
that allows reducing splitting from
klystrons. CSC, 13.9.2006
Highlights WP 2 – Normal
The Russian ISTC DTL Prototype is late by 5 months (and some technical points are not clear yet):
will be delivered to CERN at best in August 2007, quite late for the decision on Linac4 DTL.
New layout (with coupling cell) of the CH cavities made at
Frankfurt for GSI
(Linac4) finally under
high power RF testing
at CERN (1yr late).
CCDTL prototype made
in Russia waiting for
some brazed parts
(priority to LHC).
One cell of cold model of SCL
for Linac4 finally made at
LPSC – activity about 1 year
late, concerns for Linac4.
10 CSC, 13.9.2006
Highlights WP 3 –
Preparation of 704 MHz test stand in Saclay:
-klystron (CPI) on schedule, should be delivered before end 2006.
-HV power supply to be assembled before end of 2006
Progress in the design of spoke
cavities + definition of a spoke layout
in competition with NC designs.
11 CSC, 13.9.2006
Highlights WP 4 – Beam
Chopper tests at Saclay:
The persisting delays in the IPHI RFQ (machining+brazing) would put at risk the
HIPPI chopper tests: delivery of the RFQ at CERN foreseen only at end 2008.
A temporary set-up has been defined to allow testing of CERN chopper at
Saclay in 2nd half 2008.

WP 4 – Beam chopping
Vacuum test of CERN chopper made (2 E-9
mbar reached last Monday).
Driver prototype should arrive mid-September
and power tests can start soon.
