  1. Status of HIPPI – September 2006 Maurizio Vretenar Alessandra Lombardi 1

  2. HIPPI in 2006 • Exactly mid-way through the project • 8 deliverables and 4 milestones in 2006: large # of deliverables 2

  3. 2006 Milestones and Deliverables Dec. 06 Dec. 06 OK Dec. 06 Feb. 07 Oct. 06 ? Oct. 06 OK OK 3

  4. Status of Milestones - Deliverables List prepared by AL with links: 4

  5. Dissemination & Reports • (info from Alessandra): • 17 CONF papers (EPAC and LINAC Conferences in 2006). • 7 CARE Notes (some HIPPI-DOC have been promoted to CARE Notes). • 2 CARE Reports • 1 HIPPI-DOCument • 2nd Quarterly Report 2006 completed (6.9.06). 5

  6. 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 WP’s (resp. Coordinator) • 2 talks on the status of the linac projects covered by HIPPI (GSI and CERN). • More time for the ESAC 6

  7. HIPPI06 Preliminary Programme Programme will be finalised on Sept. 15th. Slides on the web (for the ESAC) one week before the meeting. 7

  8. 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 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. 8

  9. 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. 9

  10. 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. 10

  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. 11

  12. Highlights WP 4 – Beam chopping 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. The CERN chopper line as it will be mounted on the IPHI RFQ support at Saclay. 12

  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. 13

  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). 14
