We designed a new network architecture, the P-Mesh, which combhres the scalabili_, and fault resilience of a torus with the performance of a switch. We compare tire scalability, performance, and cost of the hub, switch, torus, tree, and P-Mesh architectures. Tire latter three are capable of scaling to thousands of nodes, however, the torus has severe(More)
A search for the decay of the charmed meson Do t K’e+eis presented, based on data collected at the $(3770) resonance with the Mark III detector at SPEAR. No evidence for this process is found, resulting in an upper limit on the decay branching ratio of 1.7 x 10m3 at the 90% confidence level. Invited paper contributed to the XXIVth International Conference(More)
The components of the SLD barre1 Cerenkov Ring Imaging Detector (GRID) are now built and are being installed. We report on tests of these, including tests of the fiber optic calibration system, detailed studies of electron drift paths on production drift boxes and detectors, tests of the dynamic gating system and its effect on drift path distortions due to(More)
We report on the electrostatic design and related measurements of the barrel Cherenkov Ring Imaging Detector for the Stanford Large Detector experiment at the Stanford Linear Accelerator Center Linear Collider. We include test results of photon feedback in TMAEladen gas, distortion measurements in the drift boxes and corona measurements. * Work supported by(More)
FORTRAN is widely viewed as the programming language of choice for scientific and numerical computations. However, limitations of the language lead some to argue that it should be replaced by another language which better lends itself to the production of structured and maintainable code. We provide quantitative data relevant to this argument by reporting(More)

The SLD Barrel Cherenkov Ring Imaging Detector was .fully operational in the 1992 physics data run. The electron drift velocity and magnetic field deflection of electron trajectories have been measured. Cherenkov rings have been observed from both the liquid and gas radiators. The number and the resolution of the angle of Cherenkov photons have been(More)
