INTRODUCTION
The current experimental programme at CERN is summarized in this electronic
version of the Grey Book. The experiments listed used one of the following
machines: the Large Electron Positron Collider (LEP), the Super Proton
Synchrotron (SPS), the 28 GeV Proton Synchrotron (PS), including
the Antiproton Decelerator (AD) for slow antiprotons and the ISOLDE facility
for short-lived ions. Five experiments have been approved for installation at
the Large Hadron Collider (LHC) and the R&D projects aimed at
developing new detector technologies and data acquisition systems for the LHC
experiments are also listed.
A number of 'Recognized Experiments' are also listed. As a complement to
CERN's Scientific Programme, these experiments, considered to be of importance
to High Energy Physics, have been given, on a case by case basis, this
recognition status by the Research Board. The groups concerned can benefit to a
limited extent from CERN's infrastructure and services.
In addition, some information about experiments completed prior to 1974
is gradually being added.
The general conditions applicable to experiments performed at CERN can
be consulted at
http://cern.ch/committees/GeneralConditions.pdf
The conditions for becoming a recognized experiment can be found at
http://cern.ch/recognized-experiments/
The Director-General of CERN establishes the experimental programme on
the advice of the Research Board
http://cern.ch/committees/rb/welcome.html
The latter acts on recommendations made by the Experiment Committees:
The INTC http://cern.ch/committees/intc/welcome.html
The LHCC http://cern.ch/committees/lhcc/welcome.html
The SPSC http://cern.ch/committees/spsc/welcome.html
Schematic layouts of the experimental areas and of the
beam lines at the different machines can be accessed from the Grey Book home
page. Each experiment, with the exception of the LEP and LHC experiments, is
identified by a code denoting the machine or the experimental area, together
with a serial number. Some experiments have adopted a mnemonic to facilitate
their identification.
The schedules for the experiments at the accelerators can be found as
follows:
PS Fixed Target
Programme: http://cern.ch/ps-schedule
SPS Fixed Target
Programme: http://cern.ch/sps-schedule
Each experiment (usually accompanied with one figure) is briefly described
together with the list of current participants and the official collaborating
institutes. The names of the scientific spokesperson and contact person, the
approval date(s) and references to the relevant Committee documents are also
given. The status given for each experiment (preparation/data taking/completed)
and for the Research & Development projects (in progress/completed)
corresponds to the current situation (updated nightly). The 'completed' status
means that data-taking has finished but the analysis may still be continuing.
The information concerning experiments is maintained by the experiment
secretariats in the case of the larger experiments and by the Grey Book team
for the smaller experiments, using the PIE application, and is
updated continually. The validity of the data is the responsibility of the
Spokespersons and Contact persons for each experiment. It is a requirement
that, before their names can appear in the Grey Book, participants in
experiments should either be registered with the CERN Users' Office or have
provided a minimum of information about them.
The Grey Book is not an official CERN document; the Minutes of the
Research Board and of the Experiment Committees are the appropriate official
references.
The experiments’ secretariats and the Grey Book secretariat deserve full
credit for collecting and preparing the material. They should be contacted for
further information, or for comments and possible corrections, at the Experiment
secretariat e-mail address indicated on the experiment page.
The GS-AIS group is to be thanked for installing the Web version of the
Grey Book.
Updates and corrections to the institute addresses etc. should be sent
to info-greybook-institutes@cern.ch
