16:00 → 16:05 Magnets - Old measurements

Update on action: There should already be some numbers available from measurements at SM18, these should be looked into. (These low current results were not studied before since they were not relevant before now.)

Speaker: Ezio Todesco (CERN)

16:05 → 16:10 Magnets - New measurements

Update on action: The measurement program on the bench in SM18 should be extended to investigate reproducibility.

Speakers: Attilio Milanese (CERN), Ezio Todesco (CERN)

16:10 → 16:15 Magnets - Hysteresis margin

Update on action: Find the margin needed for hysteresis, between operational current and I_standby.

Speaker: Ezio Todesco (CERN)

16:15 → 16:20 Magnets - Ramp down

Update on action: Check whether ramping down instead of injecting at low energy would make sense.

Speaker: Ezio Todesco (CERN)

16:20 → 16:25 LHC power converters - Updated I_standby

Update on action: Update the data on minimum stable currents of LHC magnet power converters.

Speakers: Matteo Solfaroli Camillocci (CERN), Mike Lamont (CERN)

16:25 → 16:30 Operational possibilities - Single bunch SPS

Update on action: Check whether there is a way to ensure there is only ever one bunch in the SPS, so that some settings can be masked instead of changed?

Speaker: Verena Kain (CERN)

16:30 → 16:35 Operational possibilities - Need for dump?

Update on action: Check if we need the dump, e.g. could we steer into collimators instead of dumping.

Speaker: Jan Uythoven (CERN)

16:35 → 16:40 Measurement planning - Measurement list

Update on action: Make a list of measurements and check if a pilot/indiv bunch would be enough for all of them, and how many of these bunches we need in the machine at once (hopefully one).

Speakers: Ezio Todesco (CERN), Matteo Solfaroli Camillocci (CERN), Mike Lamont (CERN)

16:40 → 16:45 Measurement planning - Top energy

Update on action: Define the energy we need to ramp to, depending on measurements needed.

Speakers: Ezio Todesco (CERN), Matteo Solfaroli Camillocci (CERN), Mike Lamont (CERN)

16:45 → 16:50 Measurement planning - Time details

Update on action: Assemble first overview of steps and measurements needed to give better estimate of the amount of time we need to request.

Speakers: Brennan Goddard (CERN), Linda Susanne Stoel (Nikhef National institute for subatomic physics (NL))
