ATF Users' Place

Prior to Arrival at BNL

  1. To participate in an experiment, a guest number assignment is required. To obtain one, complete the BNL Guest Information System form. Non-US citizens should expect at least 60 days for processing.
  2. After you are issued a BNL guest number, complete as much of the online ATF training as possible.
  3. Consult the Experimental Work Guide (PDF) for important information on planning experimental work and installations at ATF.
  4. In order to use your scheduled beam-time, an Experimental Safety Review (ESR) must be completed. Submit the experimental details and hazards of your experiment to the ATF ESH Coordinator, who will populate the ESR form. The ATF ESH Coordinator will submit the finalized ESR form to the C-A Department for formal review and approval. The PI or local representative may be asked to give a presentation as part of the review process.
  5. The ESR process may take two months or more, so please start as early as possible. Installation at ATF may not begin until the ESR is approved.

Upon Arriving at BNL

  1. Report to the RHIC & AGS Users' Center to receive BNL training, dosimetry badge and ID card.
  2. Complete ATF Awareness Training, given by the ATF Safety Officer. Additional specialized training may be necessary depending on your experiment (e.g. laser training). Please contact the ATF ESH Coordinator for additional information upon arrival.

See the Visitor Information Guide for a variety of information to help you make the most of your experience at Brookhaven.

Beam Time Allocation

  1. Beam time is allocated according to the requirements of the experiment and the availability of beam time. To make a request, complete the shift request form and submit via email to the ATF User Coordinator. See beam time schedule.
  2. ATF operators start the machine for scheduled experiments at 8:30 AM. The actual run time of the experiment will start at 9 AM and this time will be entered in the ATF Operations Logbook as the start time of the experiment. Normal ATF operations end at 5 PM. If an experimental program requires time beyond these regular operation times, a duty operator must be identified and a proper shift change take place and recorded in the ATF Operations Logbook.
  3. The accounting of time allocated to each experiment will be based on the records of ATF Operations Logbook. ATF operators will keep a record for all unscheduled maintenance that may take place during the scheduled ATF operation and that time will not be considered as allocated experimental beam time.
  4. It is the experimenter's responsibility to fill the ATF Experiment Logbook. The ATF Experiment Logbook shall include the experiment's name, the task of the day, major machine parameters, timed record of the experiment and a summary of major experimental results.
