It is shown that compact designs of multifocus, conical approximations to highly nested Wolter I telescopes, as well as single reflection concentrators, employing realistic graded period W/Si or Ni/C multilayer coatings, allow one to obtain more than

We discuss a hard x-ray telescope for the range 25–70 keV based on a one-dimensional lobster-eye telescope and x-ray supermirror coatings. This approach enables wide field-of-view imaging. A telescope suitable for a large balloon payload, with a 50

We present the conclusions of a panel discussion held on the final day of the workshop. The major themes discussed by the panel involved increasing standardization, sharing information, improving access to space, and the changing role of the Principa

We show that a crystal spectrometer used in the Laue mode is a useful diagnostic of high‐energy x‐ray emission from laser fusion plasmas. It has good collection efficiency and adequate energy resolution for continuum measurements. The instrument

Despite recent progress with the detection of afterglows of Gamma Ray Bursts (GRBs), the nature of these events is unknown. However, important clues to understanding what the GRBs are, may very well be found by studying the x-ray afterglows. The comb

During the 10-year lifetime of the x-ray detectors, the Vela spacecraft provided data on many new types of sources. Cen X-4, an exceedingly bright x-ray transient, was observed in the summer of 1969, shortly after launch, and did not return to the x-

Via simultaneous multicolor photometry and polarimetry of AM Herculis, we find correlations among polarization, flux, and color in the V and I bands in periodic and nonperiodic (i.e., flickering) activity. The primary minimum observed in both bands i

All 5 yr of 3-6 keV monitoring of Sco X-1 by the Ariel 5 all-sky monitor have been reanalyzed to search more sensitively for variation at the 0.787313 d orbital period. The best limits on orbital variations come from data selected to exclude active e
