Spectroscopy and decays of charm and bottom
After a brief review of the quark model, we discuss our present knowledge of the spectroscopy of charm and bottom mesons and baryons. We go on to review the lifetimes, semileptonic, and purely leptonic decays of these particles. We conclude with a brief discussion B and D mixing and rare decays.

Excited charmed mesons
The experimental status of excited charmed mesons is reviewed and is compared to theoretical expectations. Six states have been observed and their properties are consistent with those predicted for excited charmed states with orbital angular momentum equal to one.

Prospects for heavy flavor physics at hadron colliders
The role of hadron colliders in the observation and study of CP violation in B decays is discussed. We show that hadron collider experiments can play a significant role in the early studies of these phenomena and will play an increasingly dominant role as the effort turns towards difficult to measure decays, especially those of the Bs meson, and sensitive searches for rare decays and subtle deviations from Standard Model predictions. We conclude with a discussion of the relative merits of hadron collider detectors with ‘forward’ vs ’central’ rapidity coverage.

B physics at the Fermilab Tevatron after the year 2000
Abstract The requirements for second-generation B experiments at hadron colliders are discussed. The prospects for mounting such an experiment at the Fermilab Tevatron Collider are reviewed. Early results from a design study which is intended to produce an optimum detector for the Tevatron are presented.

The lead glass columns: A large shower detector at the SLAC hybrid facility
Abstract A large lead glass shower detector containing 204 lead glass blocks and 250 finger hodoscope elements has been constructed and operated in a photoproduction experiment at the SLAC Hybrid facility. An energy resolution of σ E /E = (0.84+4.8/E 1 2 )% has been achieved for electron energies between 4 and 16 GeV. Details of the apparatus, its stability monitoring system, and its use in triggering the bubble chamber are presented. The performance of the detector in electron identification and π0 reconstruction is discussed.

Precision synchrotron radiation detectors
Precision detectors for measuring synchrotron radiation beam positions have been designed and installed as part of beam energy spectrometers at the Stanford Linear Collider (SLC). The distance between pairs of synchrotron radiation beams is measured absolutely to better than 28 mu m on a pulse-to-pulse basis, thereby contributing less than 5 MeV to the error in the measurement of SLC beam energies (approximately 50 GeV). A system of high-resolution video cameras viewing precisely aligned fiducial wire arrays overlaying phosphorescent screens has achieved this accuracy. Detectors of synchrotron radiation using the charge developed by the ejection of Compton-recoil electrons from an array of fine wires are being developed.<<ETX>>

Progress in Understanding RAMP Rate Sensitivity in High Energy Booster Dipole Magnets
Quench current on some string test magnets decreased significantly with increased ramp rate. As subcontractor for the design and development of the HDMs, Westinghouse is responsible for ensuring that HDMs reach full field during the bipolar operating cycle which ramps at 62 A/s, compared with only 4 A/s for CDMs. Our objective is to specify and control design and processes to consistently produce magnets that meet ramp rate requirements. Understanding observed ramp sensitivity is necessary, along with aggressive testing of candidate design and process improvements.
