Upsilon - Brief History

 

BRIEF HISTORY OF THE WORK LEADING TO UPSILON
(Compiled by the Experimenters)
June, 1970 Proposal to measure single lepton pairs at Fermilab (E-70), experimenters propose to find a heavy particle, "Publish and become famous."
Summer, 1971 Lead glass tests at Cornell's Wilson Electron Synchrotron and Brookhaven AGS
March, 1973 First apparatus at Fermilab in Proton Center Target Hall (invention of rain shields!)
May, 1973 Experiment to serarch for long-lived, heavy particles using the proton beam line as an analyzing device (E-187) (none were found?)
Sept., 1973 First setup for high PT single electron search (discovery of anumalously large yield of electrons and muons at large angles announced!)
June, 1974 Lepton pair experiment renamed E-288 (for reasons known only to the 2nd floor?)
Oct., 1974 First crude attempt to observe muon pairs (a crude reaction to the exciting discovery of the J/Psi at SLAC and Brookhaven)
Dec., 1974 Search for Φ mesons as a source of high PT Leptons (a wild goose chase!)
Aug., 1975 First electron pair setup (discovery of superbuckets in the accelerator!)
Feb., 1976 First muon pair setup (muon pairs look promising for the future, Super 288 planned!)
May, 1976 High mass hadron pairs (E-494) and more electron pair running (Stony Brook physicists join the collaboration)
April, 1977 Installation of "Super 288" with new target box and improved muon spectrometers (with a sensitivity 400 times grater than the 1975 electron pair experiment)
June, 1977 Announcement of results at Fermilab including 950 events near 9.5 GeV/c, the Upsilon.
