You MUST complete a dry run of your
experiment before conducting your first NSRL run.
an exposure, the time you need for each sample
exposure should include time to change samples. If
RHIC is running, the sample changing time is
approximately 7 minutes. If RHIC is not running,
time to change samples is only about 4 minutes.
The size of the radiation field that can uniformly
expose a set of samples can be as large as 20 x 20
cm2 for most ions and energies. By special
request, the NSRL beam can operate in Large Beam mode
with a 60 x 60 cm2 usable beam size.
For users preparing cell exposures, and
Incubator is available to keep cell samples at a
constant temperature and humidity during the length
of their exposure. The exposure field for samples
inside the incubator is only 15 x 15 cm2.
Standard sample holders are available for cells
at NSRL. Holders for various types of T75,
T25, and test tube sizes have already been made up.
If the sample holders do not fit your needs, custom
sample holders can be prepared with a few hours
advance notice. If you are bringing your own
sample holders, make yourself familiar with the
information regarding beam
fragmentation and the documentation on sample
flipper is available that allows flasks to
remain horizontal until the time of exposure,
keeping the cells in the medium as long as possible.
There are multiple
sample holders that allow up to 10 samples to
be placed in the beam per exposure. In most
cases, the time taken to load the samples into the
sample holders is longer than the exposure itself,
and so there is no benefit in planning to expose a
large number of samples in a single entry. At
the request of users, custom sample holders can be
fabricated at NSRL with only a few hours notice.
For exposures to only part of a sample,
collimators can be arranged that shield all parts of
a sample except for the region to be exposed.
Physics experiments can make use of several sample holders that
make exposures more efficient.
table allows experiments to be mounted centered
on the beam and rotated to any angle with an
accuracy of ~1 degree.
table allows many samples to be mounted on a
table that can be remotely controlled to move
samples into or out of the beam without any access
Users are expected to bring self-contained
experiments, but there exists a data acquisition
facility at NSRL composed of a VME crate with a
variety of ADCs, TDCs, and Scalers that can be used
to accommodate most physics experiments.
Data rates in excess of 2kHz (600 events per spill)
are practicable, with data recording in the format
of ASCII files or ntuples. Contact the NSRL
Liaison Physicist at 631-344-3096 or 631-344-6102

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.
