TECHNICAL PROGRESS REPORT
During 1979, the research program in experimental high energy physics
at The Rockefeller University has made substantial contributions to the under-
standing of both strong and weak interactions. The new results have been re-
ported at several international conferences and some of them are now published
or have been distributed as technical reports. A list of the published work
is attached as Appendix A.
The principal Laboratories which have been utilized in this work are
the 500 GeV accelerator at Fermilab and the Interacting Storage Rings facility
at CERN. The latter is a facility unique in the world which provides the highest
available energies for proton-proton collisions.
The results of the individual experimental projects obtained during 1979
are described in some detail below. Section II discusses the experiment at the
CERN ISR; Section III discusses the three research projects at Fermilab.
II. RESEARCH PROGRAM AT THE CERN ISR: ,
Routine data taking of the CERN-Columbia-Oxford-Rockefeller experiment
R-108 at the CERN ISR continued in 1979 with the same running conditions as in
1978. Data taking was completed on July 16, 1979.
A modification of the apparatus used in experiment R-108 which extends
the region of photon and electron detection to the entire azimuth, complementing
the full azimuth charged particle detection already available, was proposed on
February 28, 1979 and approved on March 23, 1979. This new configuration (R-110,
Figure 1) provides a factor of ^ 4 increase in acceptance for the detection of
e+e” pairs. The new shower counters are made of conventional lead and scintil-
lator. The experiment has been installed in the ISR and is now in the testing
stage. An enormous amount of support was provided by CERN in order to get the
experiment installed in such a short time.
Here’s what’s next.
