Run Plan

Please help keep this list complete and up to date.

Important notes

Always: Please Keep F:MC6IC at or below 2E9 ppp (for halo management reasons)
Communicate with the MCR to keep the primary protons at this device close to this level.

If the Wire Chambers trip too often (several times per hour), turn off the power supply! And call the run coordinator.

In case the beam goes down

This condition is now handled automatically. Do nothing special unless the DAQ will not run. As usual, call and expert if you cannot solve the problem quickly on your own.

Missing Switchyard signals $30 and $36 should be faked by an ACNET script if they are dropped from the timeline:
  • If the last SWYD was < 120 seconds ago, go to/stay in Beam On mode
  • If the last SWYD was >120 seconds ago, go to/stay in Beam Off Mode by sending fake $30 and $36 based on $00 and delays

Current Runs

If asked by MCR what kind of beam you'd like please specify these:

  • MC6IC less than 2E9
  • Steady intensity during the spill: Linear rise on MC6IC during the spill.
  • MC7U09 and MC7U10 minimized while
  • MC7U11 and MC7U12 maximized

For the other parameters, see the table below.

(If a 'quantity' i.e. BEAMON, is the first in the list, and doesn't have a sign (+ -) in front of it, it's assumed to be positive).
