General Information (Gianluigi)
LHC status:
Commissioning with beam started
Beams accelerated to 4 TeV
Commissioning of the squeeze to b*=60 cm ongoing
Aim to accumulate 15 fb-1 by the end of the year.
A joint LIU-HL/LHC brainstorming meeting will take place on Friday 30/3 to discuss the between LIU and HL/LHC parameters in the auditorium in building 30. The agenda is available at: http://indico.cern.ch/conferenceDisplay.py?confId=175259
Gianluigi will be absent from Monday 26/3 afternoon until Wednesday 28/3 afternon (included)
Round Table (all)
Antoine
The MTE cycle has been set-up and the measurement campaign is about to start. Beam measurements will be performed in parallel to magnetic measurements next week. Marco Buzio and team will measure quadrupolar component of the PS main magnets on-line.
Adriano
Adriano has contacted people from HIT and HIMAC to get information on their slow extraction schemes. He will discuss with J. Tuckmantel for the RF noise generation.
A meeting has taken place last week with Adriano, Christian, Detlef Kuchler and his student to see the possible species of light ions.
Raymond
The optics with larger dispersion and beta functions using the gamma jump triplets to reduce the space charge tune spread will be tested in experiments.
Raymond is also going to start measurements of the PS resonant terms with F. Schmidt. Gianluigi suggested to consider the option of using the PS transverse feedback as an AC dipole for these measurements in case the decoherence is too fast.
Vincenzo
Vincenzo is conducting convergence studies with PTC/ORBIT for the PSB to determine the parameters to be used for the space charge simulations
A working point below the half integer is being considered for the moment
Adrian
Helping with the data taking for the SPS scrubbing.
