This report contains summaries of 736 approved current and recent experiments in elementary particle physics. A glance at the summaries in the body of the report will show the kind of information given. Experiments at the following laboratories are included:
Brookhaven (BNL) KEK CERN Los Alamos (LAMPF) CESR Novosibirsk DESY Paul Scherrer Institute - formerly SIN (PSI/SIN) Fermilab (FNAL) Saclay Institute for Nuclear Studies, Tokyo (INS) Serpukhov Institute for Theoretical and Experimental SLAC Physics, Moscow (ITEP) TPJUMF Joint Institute for Nuclear Research, Underground experiments (UNDERGROUND) Dubna (JESTR)
We exclude experiments that finished taking data before 1982. The rationale for thus including many rather old experiments is that many of them are still producing papers; note that the sum maries include lists of journal papers. Sources of information — Our first information about an experiment usually comes from the proposal for the experiment. Then we follow the progress of the experiment as best we can in laboratory reports such as "Experiments at CERN in 1988." Finally, a few months before an edition of this report is to appear, we send copies of the summaries of the experiments to the spokespersons for checking and updating. If a reply is received — as was the case for more than one-half of the experiments — there is a 'V " next to the spokesperson on the summary. Since current experiments are often in flux, we rely heavily on these replies to be up to date: no •/ by the spokesperson means the summary may be inaccurate or incomplete. (For a handful of experiments, we verified our information with a local member of the experiment, not the spokesperson, but for simplicity put a ^ by the spokesperson. Also, for experiments with more than one spokesperson, a request for verification was sent to only one of them, but all the spokespersons are checked if the one replied.) Computer database — This report is produced from a computer database maintained at SLAC under the SPIRES database management system. The database, named EXPERIMENTS, also contains information from earlier editions of this report about many experiments completed before 1982 (going back to about 1975, and including experiments at Argonne and Rutherford). See page 3 for a guide to using the EXPERIMENTS database online. Abbreviations — To keep the summaries brief, abbreviations are used to indicate journals, kinematic variables, accelerators, and detectors. The abbreviations are usually obvious but are defined near the beginning of the report. The abbreviated forms are needed for searching the EXPERIMENTS database online. Properties of particle beams — Tables at the back of the report summarize the properties of beams for fixed-target experiments at Brookhaven, CERN, Fermilab, KEK, LAMPF, Saclay, Serpukhov, SLAC, and TRIUMF. Supplement on detectors — This report has a supplement entitled "Major Detectors in Elementary Particle Physics." The second edition, describing 49 detectors, appeared in May 1985. For each detector, there is a 2-page summary giving properties and performance characteristics and a diagram. We hope to produce a third edition in 1990.
1 Acknowledgments — We thank L. Addis (SLAC) and A. Konrad (LBL) for help with the SPIRES database system, and the hundreds of spokespersons who took the time to reply to our inquiries. Comments and requests — We invite comments pointing out omissions, obscurities, out- of-date information, and errors. Comments should be sent to: EXPERIMENTS Particle Data Group (50-308) Lawrence Berkeley Laboratory Berkeley, CA 94720 USA Requests for copies from the Americas, Australasia, and the Far East should go to the above address, while those from other areas should go to: CERN Scientific Information Service CH-1211 Geneva 23 Switzerland
2 SEARCHING THE "EXPERIMENTS" COMPUTER DATABASE ONLINE
General information — As mentioned in the Introduction, the summaries in this report and sum maries of many earlier experiments are contained in a computer database named EXPERIMENTS main tained at SLAC under the SPIRES database management system. Anyone with an account on the SLAC IBM 3081 computer may access this database online. If you have an account but are unfamiliar with SPIRES, a "Guide to VM SPIRES" is available from the SLAC Library, Bin 196, SLAC, P.O. Box 4349, Stanford, CA 94309, USA (phone: 415/926-2411). If you do not have an account and cannot find anyone who does (at major laboratories, ask at the library), contact Louise Addis of the SLAC Library. If you just want to try out the system, contact us about using a temporary guest account: Particle Data Group, 50-308, Lawrence Berkeley Laboratory, Berkeley, CA 94720, USA (phone: 415/486-4724, or FTS 451-4724). The EXPERIMENTS database is also available under a different system in Europe (contact M. Whalley, Dept. of Physics, Univ. of Durham, South Road, Durham DH1 3LE, UK) and in the USSR (contact V. V. Ezhela, Inst, for High Energy Physics, Serpukhov, Moscow Region, USSR). Logging on to SPIRES — If you will be communicating with the SLAC computer at 1200 baud or less (such as over telephone lines or with a hardcopy terminal), you will probably want to run in line-by line mode, in which case you need to set your terminal/modem for half-duplex operation. If you will be communicating at a speed greater than 1200 baud, you will probably want to run in full-screen mode, in which case you need to use fuU-duplex, even-parity, 7-data-bit operation. You will usually connect to the computer through the MICOM switch, which will ask you what "class" you want. If you are set up for line-by-line mode, type: VMLINE If you are set up for full-screen mode, type: VM In full-screen mode, you will then be asked to type a carriage return, and for the kind of terminal you are using (e.g., VT100 or ADM3A). Finally, in either mode, type an extra carriage return after you see the message VM/370 ONLINE. In full-screen mode, whenever the screen fills up (indicated by the word MORE at the bottom), you may clear it by hitting the CLEAR key (which may be ENTER, CONTROL-L, or CONTROL-Z on your terminal — note this is not the same as a carriage return); if you don't clear the screen, the computer will do so automatically after a minute or so. (You can hold the screen indefinitely by hitting a carriage return.) Also, if you are listing information and want to abort the listing, type HT and a carriage return before hitting the CLEAR key. In line-by-line mode, you can abort a listing with the BREAK or ATTN key. After going through the above connection procedure, log on to the computer by typing: Logon
3 Searching the EXPERIMENTS database — A brief description of how to use the EXPERIMENTS database under SPIRES follows. To access the EXPERIMENTS database, type: SElect EXPERIMENTS To find out the indices that are available for searching in this database and the various names you may use to refer to them, type: SHOw INDex To see a random selection of values in an index (and thus determine the form to use as a search value), type: BROwse
Searching Problems: There are three common reasons why a search may fail spuriously: (1) For searching in the SPIRES database, all energies and momenta are in GeV and GeV/c. (S) Any search value containing any of the special characters ( ) < > = must be enclosed in double quotes; see the examples above for CITATION, REACTION, and PARTICLE. (3) You may have used an incorrect form of the value for which you were searching (e.g., an incorrect particle or experiment name). To find the correct form, use the BROWSE command for the index you are searching (see above), or look in the lists of names and abbreviations beginning on page 25. Note, in particular, that in reaction and particle searches, an antiparticle name is formed by following the corresponding particle name with BAR (thus the antiproton is written as PBAR); in title searches, particle names are somewhat variable in their spelling, and several forms may be used.
4 After entering a FIND command, you will be told the number of experiments satisfying the criteria given. You then have several options: (1) You may list out the information available for these experiments by typing: TYPe (or TYPe PAUse if you are in line-by-line mode on a CRT terminal)
You may abort a long listing by hitting the BREAK or ATTN key if you are in line-by-line mode, or by typing HT followed by a carriage return followed by the CLEAR (ENTER, CONTROL-L, or CONTROL-Z) key if you are in full-screen mode. You may sometimes get the word HOLDING in the lower right-hand corner of your terminal. Hit the CLEAR (ENTER, CONTROL-L, or CONTROL-Z) key to resume.
Or (2) you may narrow the list already found (i.e., add more selection criteria) by typing: AND

The second element gives the size or name of the chamber. Where appropriate, a third element, one of HYB, RAP, or TST, indicates that the chamber is part of a hybrid system, or that it is rapid cycling, or that it contains a track-sensitive target.

Bunce, BNL) Up to 10u protons per pulse are accelerated typically to 28.5 GeV kinetic energy (31 GeV has been obtained). At 28.5 GeV, the period is 2.4 sec for slow extraction (with a 1-sec Battop), or 1.4 sec for fast extraction (used for neutrino beams). Counting rates may be estimated using the nominal beam spill time of 1 sec. The beam lines with 0° production angles can be used for polarized protons and/or for heavy ion beams.
