  1. Booster & Transfer Lines LIU_L4 [M.Vretenar] LIU_PS [S.Gilardoni] LIU_PSB [K.Hanke] entry plane distributor entry plane PS inj. septum

  2. What has been done, what is still on the list • work package within the Booster upgrade TF, representative Jan Borburgh • impact has been analysed in great detail by Jan, ref EDMS 1082646 v3 • (includes work by Brennan, Simone/S.Aumon, …) • - identified equipment to be replaced / upgraded / modified - completed • detailed cost break-down, spending profile & time lines - completed • - different scenarios for PS injection have been studied - longer PS inj. septum • requires re-design of the injection region – in progress • Still on the list: • Final confirmation of the lay-out of the injection region pending • Presentation at the UGWG scheduled for November 2010 • now part of LIU_PS, but has an impact on the whole lay-out of the line

  3. Survey of Equipment (from EDMS 1082646 v3) • BE.BSW: magnets and generators OK up 2.2 GeV • BE.KFA14L1: not enough margin on magnets (OK up to 1.7 GeV, ferrite • saturation above); design new magnets and vacuum vessel. Generators OK • up to 2 GeV • BE.SMH: magnet successfully tested at current equivalent to 2 GeV • operation;cooling and interconnects to be reinforced • BT.SMV10: not enough margin on magnet (OK up to 1.75 GeV); longer • magnet to be designed • BT.KFA10: magnets and generators OK up to 2 GeV; it is advisable to replace • the ferrites by more performing ones to run at 2 GeV or higher • BT.SMV20: not enough margin on magnet (but OK up to 1.9 GeV); longer • magnet to be designed • BT.KFA20: magnets and generator OK up to 2 GeV • PI.SMH42: not enough margin on magnet (1.4 GeV max.). Needs new PS • injection scheme to accommodate the additionally required length for the • septum magnet; • PI.KFA45: magnets OK but no margin on generator (1.4 GeV is the limit if • magnets are terminated). If magnets are used in short-circuit mode, 2 GeV is • attainable, but with increased rise and fall times as well as increased ripple on • the flat top.

  4. Recombination Elements BT4.BVT10 BT4.SMV10 BT4.KFA10 from R4 from R3 from R2 BT.KFA20 BT.SMV20 from R1 BT.BVT20 BT1.KFA10 BT1.SMV10 BT1.BVT10

  5. Time Lines

  6. Budget

  7. Requirements and Constraints • Scenarios (1) and (2) were found cost equivalent; scenario (3) gave no significant • savings but an unacceptable loss of non-LHC physics time • Design choices of the Task Force: • - 2 GeV upgrade for all beams to the PS • - Beams to ISOLDE remain unchanged at 1.0/1.4 GeV (although they have expressed • already interest in 2 GeV) • - BTP line remains non ppm • PSB extraction must be ppm between 1.0 GeV and 2.0 GeV • New arguments have recently been raised by C.Carli • Changing these constraints should be done at the LIU level only

  8. Responsibilities, Interfaces, Coordination plus a number of people, who are not representing a group but are experts in certain areas or somehow involved, e.g. LARP, design office, …

  9. Responsibilities, Interfaces, Coordination LIU • Booster Upgrade Project LIU_PSB • all groups involved have nominated representatives • working group is central place for all discussions / everybody • involved & informed • meetings open for everybody and for all suggestions • technical & design choices, t.b. confirmed by LIU project team The working group meetings are the central place to discuss and exchange information. This ensures that all groups are involved and informed. It is also the single entry point for the equipment groups.
