FY13 run

Nimble scheduling for FY13 run was a necessity

SAREC meeting, July 25, 2013, V. Yakimenko

5 months long commissioning/running

• Four beam configurations (some uncertainty in time to develop)

• Configurations were progressively more difficult

• Uncertain schedule for commissioning of the ionization laser

Smaller fraction of “Scheduled off” (mainly laser installation) and “Machine studies” are expected in next run. Accelerator availability was ~85%.

Planning for FY14 run

FY14 is expected to have much more user experimental time.Efficient use will be main challenge

Two part run is planned for FY14:

• Sept.30-Dec.20: Two bunch PWFA in 1.5m oven, positrons testing

• Feb.2-Jun.30: Beam time shared between ~12 experiments

LCLS II construction schedule is not finalized

Program Advisory Committee & User meetings

• Updates from six experiments that did use beam time in FY13 is

expected.

• 12 new proposals are submitted in addition to already ongoing

programs:

• 8 for FACET (one will be first tried at ESTB and one at NLCTA) • 3 for NLCTA• 1 for ASTA

• Detector R&D experiments at ESTB are reviewed by separate

committee

FACET time is oversubscribed


9

Charge to the Program Advisory Committee

• Evaluate the scientific merit and rate the technical risk of

the NEW proposals for the SLAC Accelerator Test Facilities.

• Determine whether the new proposals would be appropriate at

this time or in the future.

• Review existing R&D results at the SLAC Accelerator Test

Facilities and which elements need further in-depth analysis

(for example):

• Is the science unique and is the progress compelling?• Is the program making effective use of facility and lab resources?• Could the program be enhanced by expanding the collaboration?• Comment on the synergy of the programs within and between the

facilities. Are there opportunities SLAC should pursue? What

would be needed to successfully realize these opportunities?
