In 2005 the DESY Directorate established a Beamtime Allocation
Committee (BAC) for FLASH which collects beamtime requests, discusses
priorities, and makes a proposal for the beamtime allocation.

Members of the BAC include representatives from the users of the FEL radiation, the European XFEL and the Linear Collider Effort (ILC).

Beamtime topics are:

  • FEL user operation (4500 hours per year)
  • FLASH machine and photon beamline studies, user run preparation (2500 hours per year)
  • Accelerator R&D (750 hours per year)
