Abstract: The Fermilab experiment E835 is dedicated to the study of charmonium spectroscopy via direct formation of charmonium resonances in proton‐antiproton annihilations. The latest results from this experiment and their comparison to the world data are presented. The physics implications are discussed.

Abstract: A set of 144 VLPC chips has been used by experiment E835 at FNAL for the readout of its scintillating fiber detector. During the data taking, the fibers have been exposed to rates up to 2.5×104 mips/sec, corresponding to 3.5×106 photons/sec on each VLPC pixel surface. This paper reports about a study on rate dependence of gain and quantum efficiency throughout the run, as well as VLPC failure statistics during operation. No significant aging effects are observed. A review about the overall system performance is given.

Abstract: A cylindrical 860-channel scintillating-fiber tracker for the measurement of the polar coordinate θ has been built for experiment 835 at Fermi National Accelerator Laboratory; it was used during the data-taking period, from October 1996 through September 1997. The high granularity, flexibility and fast response of the scintillating fibers are combined with the high quantum efficiency of the Visible-Light Photon Counters. From this combination, a new kind of detector arises, capable of high-resolution tracking, fast first-level kinematical triggering and single/double-track discrimination. Results of the tracker performance are presented.
