 Charge to the Liaisons
There will be one person from this group permanently on shift in the
PEP-II control room during the PEP-II run.
The role of this person is to serve generally as a liaison between BABAR and
PEP-II to increase the overall running efficiency and to minimize the
background impact on BABAR. More precisely, they will:
- Help PEP-II crew to use BABAR inputs and interpret what's going on in
BABAR
- Inform BABAR of what is going on in PEP-II
- Participate in immediate running decisions (under the authority of
BABAR shift leader) with BABAR and PEP-II shift leaders
- Collect all the information useful for BABAR in PEP-II control
room
- Participate in daily BABAR and PEP-II meetings
- Analyse off-line babar backgrounds data w.r.t. respect to the
machine
- Prepare and implement the automatisation of the above tasks, where
relevant.
Note that they are not charged with a specific BABAR protection role.
BABAR protection should rely on the BABAR protection system and not on
human being interventions. However, by having a loving look at BABAR
sensors, they will certainly contribute to the overall protection, spotting
problems before they become critical. One part of the BaBar protection
system that requires regular attention from the liaison is the SVT mid-plane
PIN diodes (the "abort" diodes), whose pedestals ("abort thresholds") need to
be calibrated at least twice a day.
Administratively, they are to be considered like another BABAR person
on shift, similar to those on shift in the BABAR control room. They therefore
report during their shift to the BABAR Shift Leader.
The People and Shift Schedule
Since the 2002 summer shutdown, liaison shifters are selected from
a group of people who have been working on accelerator backgrounds or
on the radiation protection system of some of the subdetectors. Their
names are
in the following list.
If you are interested in this topics and want to join this team please contact
Giovanni Calderini. (calderin@slac.stanford.edu).
Sign up for Liaison shifts can be made using the standard web-based
Shift Schedule forms. Liaison shifts are served at the Main Control
Center (MCC), Building 005.
You can find the
liaison shift manual here. For posterity, we keep
the year 1999 liaison shift manual here.

Training Materials
Visit the Training page for more
information.
Weekly (as requested) Liaison Training Seminar
New Liaisons must attend at least one session of the
Liaison Training Seminar. This seminar includes a workshop and a hands-on
tutorial and is usually on Mondays from 9:00 to 10:30 am in the Cornelius Conference Room at IR-2.
Please note that the seminar will be held only if the Liaison Coordinator
(currently Stan Hertzbach, hertzbac@slac.stanford.edu) receives requests
from people who wish to take it.
Training Week One
Training Week One for the Liaisons was 30 March - 1 April 1999.
The workshop was held at SLAC, and most of it was videotaped. Some of the
materials are collected here for easy reference. The schedule is
here, and available materials are hyper-linked.
Useful References
These references and manuals help define the Liaison task and should
provide information about radiation backgrounds at IR-2 in general.
