Decay and snapback:
- Fidel should have trimming capabilities, but
we must be careful with implementing trims into the model.
- Feedbacks should be switched off ideally,
including all trims into the model.
- In general, we will use the settings from the previous fill.
-
Functions and timing:
No stop of ramp
during execution of functions.
-
Operation:
-
incorporation of
trims into ramp: constant, smoothed out etc. This will be configurable depending on parameters involved. The appropriate strategy will be decided based on experience with beam
.
-
Stops during snapback: snapback resolved by 500 GeV - wouldn't imagine stopping in snapback - could get messy.
-
First ramps could be done with slower speed to allow
slower snapback measurements. The discussion concluded
that this might be useful, also for other issues like beam
loss studies at the start of the ramp.
-
Baseline target energy for the first
ramp? 1 TeV, snapback should be resolved by 500 GeV.
-
Real time knobs:
Real time knobs on key beam parameters (tune, chromaticity) are planned. To be tested during commissioning
-
Time required for ramp
commissioning:
7 days are estimated for
both rings. The milestone is to have at least 2 109 p in both
beams at top energy.
-
How long will
it take before re-injection following ramp attempt?
it
will take 90 min to 120 min to recycle the machine.
