ATLAS Schedules

Beamtime at ATLAS is normally scheduled in two-month blocks. We make every effort to produce an accurate schedule at least two weeks prior to its approval in a scheduling meeting. The scheduling process is continuously ongoing with communication between ATLAS personnel and the Principal Investigator (PI) of each experiment approved by the PAC. Follow the link at the left to learn more about the considerations that go into producing an ATLAS schedule.

As we are restarting after a major upgrade, initial beam availability is uncertain. To minimize inconvenience and unnecessary travel expenses to outside users, the first few experiments to be scheduled will be those run by in-house experimenters. As fully reliable operation are re-established, we will contact the PI's of outside experiments for scheduling of their experiments.

Because of a current shortage of operators with completed training, ATLAS is restarting with initially five and a half days per week operation, from 8:00 AM on Monday to 4:00 PM on Saturday of each week. We expect to transition back to 7 days a week operation in the summer of 2014.

If you have any comments or concerns regarding this situation, please contact the ATLAS User Liaison Physicist (Shaofei Zhu,, the Scientific Director of ATLAS (Guy Savard,, or members of the ATLAS Users Group Executive Committee. Thank you for your patience and understanding.

Please contact Mrs. Barbara Weller ( or go to here for your travel arrangement as far in advance of your arrival as possible.
