HIPPI06 Meeting in Jülich

• JRA Meeting on September 27th 29th in Julich
  (FZJ, financial contribution from the Direction
  will cover banquet and internal transportation).
• Expected 30 40 participants from all
  contributing institutes 1 or 2 external.
• Confirmed participation of the 3 members of the
  ESAC J. Stovall (LANL-SNS), Y. Yamazaki
  (KEK-JPARC), A. Pisent (LNL).
• Some modifications to the structure of the
  meeting
• 4 sessions of 3 hours for each of the 4 Work
  Packages (programme under responsibility of the
  WP Coordinator)
• 1 general session covering topics between WPs
  (resp. Coordinator)
• 2 talks on the status of the linac projects
  covered by HIPPI (GSI and CERN).
• More time for the ESAC

HIPPI06 Preliminary Programme
Programme will be finalised on Sept. 15th. Slides
on the web (for the ESAC) one week before the
meeting.

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 (3243108).
• 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 Toshiba.
• The choice of 324 MHz gives a clear preference to
  a non-EU company (Toshiba) and could definitely
  cut out of the market Thales.

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), new position in an extension of
  the Linac2 tunnel.

• GSI will start ordering a klystron prototype
  already in 2006. The accelerating cavities (CH)
  have modified by adding a coupling cell that
  allows reducing splitting from klystrons.

Highlights WP 2 Normal Conducting Structures
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
CCDTL prototype (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.
11
Highlights WP 3 Superconducting Structures

• 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.
12
Highlights WP 4 Beam chopping

• Chopper tests at Saclay
• The persisting delays in the IPHI RFQ
  (machiningbrazing) 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.

The CERN chopper line as it will be mounted on
the IPHI RFQ support at Saclay.
13
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.
14
WP 5 Beam dynamics
The first bloc of the UNILAC beam dynamics
experiment planned for HIPPI was successfully
conducted end of May. The experimental data are
in the process of being compared with different
simulation codes (Parmila, Dynamion and Path).
