Injection test - Follow Up

Beam

1um pilot prepared   In preparation
Dedicated LHC cycle If problems with present supercycle  

 

Hardware

Magnets Required circuits here    
Power Converters

Should be fully tested out following hand over of sector to operations. 450 GeV and pre-cycling. Mike's list here

Sector 34 and 45 mains condamn and will remain so.

RF

Rephasing & synchronization between SPS & LHC must be established. So far SPS re-phasing not with LHC RF frequency. Requires exchanging the existing pre-pulse generation system with a new ‘LHC style’ system – will affect all SPS beams (also CNGS). To be done second half of July.

 Andy Test Mon 28th
TDI Very basic functinality required - essentially in/out Stefano OK
Collimators Configuration at IR3 - strategy to be confirmed. Stefano/Helmut/Mike
  • Locking
  • Separation dipoles
Alice
  • Injection permit
  • Status of magnets
  • Radiation monitoring
    
Vacuum
  • Clearly all valves open, interlocks tests, gaues and pumps operational. Need sector below 5 K to get valves out.
 Gianluigi Situation at point 3? Do we need 34 < 5 K

System Requirements   Issues
BLMs Mobile BLMs? Difficult apparently - won't have any extra before. Even going in during test if necessary could be problematic Bernd/Lars

 
BLM    BLM requirements Will 23 have been tested with source?    
BLM Connect to BIS and test. Bruno/Markus/Rudiger  
BPMs
  • FIFO concentration - publish and SDDS save
 Marek M.
  • Sum signal on which BPMs?
BTVs
  • Control - application and equip state
  • Acquistion - SDDS save

Extend TI2 Put in TI2 respository and LSA Massimo Done
Optics V6.503 - need also TI2/LHC continium   Done
Optics Use Old or re-match TI2 optics? Decision required.    

FIDEL

 [requirements]   FIDEL will provide coefficients for all circuits involved.
Aperture model Extend from MSI to TDI Bren Done
On-line model What are our use cases?    
  MCBYV.B4L2.B1, MCBYV.A4L2.B1 and MCBYV.4R2.B1 and MCBYV.5L2.B1    
 

Nevertheless from the oscillation and QT data I have a few preliminary findings: - QTL11R2 appears to be inverted

- polarity of QT12R2 looks OK

- data taken for QT13R2 are too noisy to conclude on its polarity; I hope to get information on this by playing with the model and comparing with better oscillation data - BPM.33R2.B1 probably has the wrong polarity

- as you know there is another (larger) optics error between Q17L3 and Q7L3; in x it is almost explained by an inversion of Q7L3 (but this is not it!); it is big, inversion of Q7L3 could explain the x data but not the vertical ones, an inversion of QTL11L3 cannot be the source of this optics error;

- MQS has no effect; perhaps not connected? (or did we not trim it correctly??)

- x and y phase advances in the arcs seem to deviate from my model; x oscillation propagates a little faster and y a little slower than I expected
