X-band accelerator structures meeting the next linear collider design requirements have been found to suffer vacuum surface damage caused by rf breakdown, when processed to high electric-field gradients. Improved understanding of these breakdown even

We have conducted an extensive series of laser damage measurements on highly reflective (HR) dielectric coatings which have yielded 1064-nm thresholds as high as 40 J/cm for 8to 10-ns pulses at pulse-repetition frequencies (PRF) of 10 Hz. Moreover, b

The Gravity Probe B mission provided two new quantitative tests of Einstein's theory of gravity, general relativity (GR), by cryogenic gyroscopes in Earth's orbit. Data from four gyroscopes gave a geodetic drift-rate of −6601.8 ± 18.3 marc-s yr−

Spherical gyroscope rotors for a fundamental experiment to test two predictions of General Relativity Theory, geodetic precession and frame dragging, were manufactured out of fused quartz and single-crystal silicon. These rotors required a mass unbal

In an effort to locate the cause(s) of high electricfield breakdown in x-band accelerating structures, we have cleanly-autopsied (no debris added by post-operation structure disassembly) an RF-processed structure. Macroscopic localization provided op

We perform an isospin and partial-wave analysis of the low-mass Nπ system in πN → π(Nπ) using new data at 14 GeV/c in the interval 0.02 < tππ < 0.5 GeV2. We study the diffractive background by means of its interference with the Δ and find th

The optical absorption of CdS was measured in a high vacuum after desorption of chemisorbed species. The absorption edge obtained under these conditions was found to be significantly different from the absorption edge obtained in air under atmospheri
