High Rate Photon Irradiation Test of an 8-Plane ATLAS Transition Radiation Tracker Sector Prototype

In this document we report the results from a high rate photon irradiation test of an ATLAS Transition Radiation Tracker 8-plane endcap sector prototype with 192 straws instrumented with near to final front-end electronics. Data was taken at the CERN X5 Gamma Irradiation Facility with a Cs photon source, and at the Weizmann Institute irradiation facility in Israel with a Gammabeam 150 Co source...

Technical Report 12 - Horn Monopulse Antenna System for Millstone Hill Radar

The 440-Mcps conical-scan tracker at the Millstone Hill radar site has been converted to an L-band 12-horn monopulse tracker utilizing a Cassegrain optics reflector system. The amplitude sensing monopulse feed illuminates a 10-foot subreflector and thence an 84-foot-diameter paraboloid with linear or either sense of circular polarization. This system conversion increased the capabilities of the...

Robust determination of optical path difference: fringe tracking at the infrared optical telescope array interferometer.

We describe the fringe-packet tracking system used to equalize the optical path lengths at the Infrared Optical Telescope Array interferometer. The measurement of closure phases requires obtaining fringes on three baselines simultaneously. This is accomplished by use of an algorithm based on double Fourier interferometry for obtaining the wavelength-dependent phase of the fringes and a group-de...
