Status of HIPPI – Technical InfoStatus 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 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.

9 CSC, 13.9.2006

Status of Linac4 & GSI FAIR linacStatus 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 Highlights WP 2 – Normal Conducting StructuresConducting 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

One cell of cold model of SCL for Linac4 finally made at LPSC – activity about 1 year late, concerns for Linac4.

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).

11 CSC, 13.9.2006

Highlights WP 3 – Highlights WP 3 – Superconducting StructuresSuperconducting Structures

Progress in the design of spoke cavities + definition of a spoke layout in competition with NC designs.

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

12 CSC, 13.9.2006

Highlights WP 4 – Beam Highlights WP 4 – Beam choppingchopping

The CERN chopper line as it will be mounted on the IPHI RFQ support at Saclay.

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.

13 CSC, 13.9.2006

WP 4 – Beam choppingWP 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 CSC, 13.9.2006

WP 5 – Beam dynamicsWP 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).
