Each year, shut-down periods for maintenance and upgrade of the storage ring and the beamlines, will be scheduled on a regular basis.
For 2007, the shutdown schedule will soon be made available.
Except for the scheduled maintenance shut-downs, beamtime is expected to be available for users 24 hours a day, 6 days a week. The dedicated day for machine studies and maintenance will be communicated soon.
For each allocation period, the schedule for beamline maintenance and upgrades, and for availability of beamtime for users will be given.
Besides up to 10% of beamtime given for proposals with charge for admission, the beamtime will be shared as follows :
-
75 % of beamtime given to academic users having applied through the regular process of evaluation by the peer review committees;
-
20 % for beamline maintenance, instrumentation and technical development, and for in-house research, under the responsibility of the principal beamline scientist who will report on its use to the Scientific Directors; this percentage can be increased up to 25% in the case of a beamline with many associate scientists participating in its operation.
- An additional fraction, up to 5%, will be left for rapid access at the discretion of the General Director after submission by the Scientific Directors or the GRIGES manager. As well as for the standard project, an experimental report has to be submitted to peer review committees.
Within the period available to users, a schedule will be identified for the different modes of machine operation (i.e. multibunch, 8 bunches, etc.).
