RHIC-AGS Annual Users' Meeting 2007
By Abhay Deshpande
The 2007 RHIC & AGS Annual Users’ Meeting was held at the
Brookhaven National Laboratory on June 18-22, 2007. Rene
Bellwied (Wayne State), the 2006 Chair Elect of the User’s
Executive Committee, led the organization of this year’s
meeting. The structure of the meeting was a little different
compared to the previous years. Usually, there are plenary
sessions and there are topical workshops in which all
experimental talks in the User’s meeting are presentations on
behalf of the RHIC experiments. A speaker usually presents his
or her experiment’s view of a particular physics topic. This
year, the workshop organizers were asked to seek speakers from
experimental collaborations who would be able to present a
particular topic, which included results from all experiments
and discuss their global significance. Thus, the focus was on
RHIC science “What have we learnt within the last year
from RHIC?” rather than “What did we learn in the last year from
PHENIX or STAR, separately?”. It was felt by the organizers that
as a result of this change, the speakers, especially the young
and inexperienced ones, would seek more information and learn
more about their science when they find out how the other
experiments at RHIC perform the same measurements. It was also
expected that this would encourage more communication across the
experimental collaborations at the grass roots level. Early
concerns about this being too difficult, and hence, unfair to
our younger users at RHIC were put to rest by some of the
broadest and most exhaustive expositions of RHIC results
presented by the youngest amongst us. The excitement and the
enthusiasm of why we do what we do, was felt not only in the
sessions, but also in the corridors through the passionate,
animated and some time even heated discussions. Ample sprinkling
of theory talks in the plenary sessions and the workshops tried
to arrive at conclusions about what all these data mean for our
understanding of the hot dense systems we seem to be creating at
RHIC and of the nucleon spin.
When the planning for the User’s meeting began, the prospect of
Run-7 seemed bleak. However, as things developed,
although short, Run-7 became a reality, thanks to the efforts by
BNL management, the UEC, and of course, our supporters at
the DOE in the office of nuclear physics. By the time of the
User’s meeting, it was indeed apparent that this run was going
to be a huge success. As such, a few plenary talks, dedicated to
the performance of the collider and the experiment were
inserted in to the program. Users and visitors got to see
grand result summaries from RHIC data so far and their
interpretations, both for heavy ion as well as polarized
proton collision physics. They also saw summaries of Run-7, both
in the collider-performance and the experiments’ data
taking. Not only did RHIC deliver record luminosity, both
PHENIX and STAR detectors accumulated more than three times
their cumulative Au-Au data sets compared to Run-3. Also
presented in the plenary session were talks about the future
science using RHIC including the science of RHIC II luminosity
upgrade and that of the Electron Ion Collider (EIC). The Interim
Laboratory Deputy Director Peter Bond and the Laboratory
Director Sam Aronson, in their presentations assured the users
of the Lab’s intention to keep RHICII and the EIC as the short
and long term goals of the Lab management. All talks
from this year’s Users meeting will be available from this
this web page. if they are not available already
, as this article goes to print.
One of the main events of every RHIC & AGS user’s meeting is the
presentation of the best thesis awards. A committee of
four from the User’s Executive Council normally goes through the
entries submitted for this competition and selects two of the
very best. As a testimony to the great effort the students
themselves, their mentors & collaborators put in to these
finished products (the theses and the young researchers who
write them), the selection of two from all the entries was
especially difficult this year. Hence five theses were selected:
three (Nathan Grau, Taku Gunji, Sevil Salur) were given
honorable mentions. The two best theses awardees were Hiromi
Okada and Corey Reed. The laboratory director Sam Aronson
presented the certificates and prizes. Seen in the picture are
the awardees and the director after the award ceremony.

Two other events deserve a special mention. First: an
informal introduction to the new Associate Laboratory Director,
Steve Vigdor (presently Indiana University). Steve will be the
new ALD for Nuclear and Particle Physics starting September 1st,
2007. He gave an informal preview on his ideas and thoughts of
RHIC’s short- and long-term future and took questions from the
floor. Secondly, this year the User meeting dinner was held at
the “Andrews by the Pond”, a restaurant in Wading River, NY. By
all accounts it was a welcome change and those who attended
seemed happy with the place, the setting and the food.
There is a saying that behind every successful event there is a
hard working local organizing team (ok, this is not how the
saying goes… but I have modified it for our purpose!). Here the
principle scientific organizers of the User’s meeting were
backed by a crew of four fabulous women: Kelly Guiffreda, Angela
Melocoton, Regina Robinson & Susan White DePace, who ran the
show from behind the scenes, so that we could focus on the
science. They deserve our sincere thanks for all their help and
effort.
