Experiment Scheduling

The JLab Scheduling Committee has been established in order to develop the goals for each accelerator/physics running cycle, develop the schedule for accelerator operations, and identify the priorities among experiments scheduled to run simultaneously.

The Scheduling Committee will consider the physics priority of each experiment, together with the long-term goals of the research program, the accelerator's ability to deliver the beams desired reliably, the time necessary to mount each major experiment, and other constraints as appropriate. An effort will be made to schedule complete experiments whenever this is deemed technically feasible. See the scheduling process for detailed information.

Following the scheduling of an experiment a formal liaison physicist will be assigned. The liaison physicist will be responsible for coordinating interactions between the lab and the experiment collaboration with particular emphasis on the equipment staging and installation in the hall and on the completion of the necessary EH&S reviews of the equipment and procedures that will be used for the experiment.

The accelerator operations representative assigned as the liaison between the experiment and accelerator operations will serve in this capacity through the completion of beam delivery for the experiment. He or she will assure that any special requirements of the experiment are conveyed to the operations staff and the relevant program deputies, so optimal use is made of beam time, and knowledge of special conditions is distributed well in advance. Also an engineer liaison will be assigned to coordinate the installation of the experiment.

To ensure adequate interactions between the experimenters during the entire course of the experiment, the hall representatives, the accelerator operations team and engineering staff, and representatives from each running experiment with the knowledge and authority to speak for activities underway in the hall (nominally the run coordinator for the experiment in progress), should attend the Accelerator Operations Scheduling meeting at 1:30 P.M. on Wednesday if their hall is to receive beam in the following two weeks, or has received beam during the past week. When an experiment has received beam during the previous week, the representative from the experiment should be prepared to summarize, as briefly as appropriate, the result of these beam operations, and to suggest any ways in which accelerator operations or efficiency of beam delivery could be improved during subsequent running.

A representative from each of the running experiments should also attend the 8am accelerator operations review meeting on any morning Monday through Friday in which they received beam during the previous 24 hours (72 hours on Mondays), or expect to receive beam during the following 24 hours (72 hours on Fridays). These representatives should be prepared to address questions regarding beam delivery to their hall, details of schedules, etc. Representatives from Halls A, B, C, and D should attend the 1:30 Monday downtime scheduling meeting as required.
