Meeting on Linac4 - PSB BI Line, 21-May-2007 - DRAFT

Giulia Bellodi; Jan Borburgh; Brennan Goddard; Klaus Hanke; Tony Fowler; Wim Weterings

- Simulations on BS1 and KSW1L1 position and strength (WW), see link in table below.
- Discussions on PAC07 paper '160 MeV H- INJECTION INTO THE CERN PSB'
- The status of the action list was discussed and updated:

Closed Issues:

Name Action Results
KH Beam offset at BI.DIS 5.2mm baseline solution, as in TDR
WW, JB, TF, LS cost / time estimate backwards compatible system estimates
BG Fall time specification KSW Presentation
FG duration or elimination of the head and tail Timing estimates

Open Issues:

Name Action Results
BG, GB Optics Matching at Injection point Still ongoing
? Fringe field specification  
BG Possibility of vertical painting  
ALL AB-BT note on LINAC4 Proposed layout (deadline - may 2007)
GB Collimation of injected beam before BI.DIS  
WW Foil Heating Simulations CNGS_2μm foil, CNGS_5μm foil, CNGS_2μm foil_4_pulses
All PSB BI Functional Specification  
WW Physical Apertures of equipment Table of BT equipment
BG Tracking of beam in case of BI.DIS failure  
  Effect Longitudinal painting on transverse painting scheme.  
TF Possibility of reducing length of KSW1L1  
  Investigate the possibility of inversing BS1 and KSW1L1 position as well as BS4 and H0 dump. Simulation of several proposals.
KH, BM Beam Instrumentation requirements in BI region  BI requirements for injection region have been added to the list of requests. A specification of the detailed requirements still needs to be written.
WW Detailed layout of Injection Region PSBLayout
GB, WW, TZ Add a Steering magnet before BI.DIS WW has informed Thomas Zickler
