Consult the Experimental
Work Guide (PDF) for important information on planning
experimental work and installations at ATF.
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.
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.
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
additional information upon arrival.
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.
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.
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.
Starting an Approved Experiment
All experiments conducted at the Accelerator Test Facility must
be reviewed for Environment, Safety and Health concerns before set-up begins.
The ATF provides no funding or free services other than beam time
to the users, including operators during working hours (8 am to 5
pm, Monday through Thursday). Friday is maintenance day and access
day to the experiment hall for service or installation of
The responsibility of constructing and operating the specific
experiment rests with the user. The use of electron beam
diagnostics, optical diagnostics, computer systems, CAMAC crates
etc. is provided at no cost.
It is the user's responsibility to install their experimental
equipment in the beam line. Users must get the approval of the
User Coordinator to break into the beam line vacuum system.
Vacuum systems must be bled to pure nitrogen for such an
operation. Following installation, the equipment must be approved
for safety by an ATF operator. This inspection should be entered
into the ATF's operations logbook.
Specialty services, such as surveys, electricians and vacuum, are
available for a charge. To enable payment for such services, users
are required to establish an account with BNL. Contact the
ATF Group Secretary to
establish an account.
Many users and experiments share the resources of the Accelerator
Test Facility. One
of the most valuable resources is cable.
Given the very large number of cables installed at the ATF, it is
absolutely necessary that the cable policy be observed.
One of ten national laboratories overseen and primarily funded by the Office of Science of the
U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical,
biomedical, and environmental sciences, as well as in energy technologies and national security.
Brookhaven Lab also builds and operates major scientific facilities available to university, industry
and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven
Science Associates, a limited-liability company founded by the Research Foundation for the State
University of New York on behalf of Stony Brook University, the largest academic user of Laboratory
facilities, and Battelle, a nonprofit applied science and technology organization.
