Details of the design, fabrication, and ground and flight calibration of the High Energy Transmission Grating (HETG) on the Chandra X-Ray Observatory are presented after 5 years of flight experience. Specifics include the theory of phased transmission gratings as applied to the HETG, the Rowland design of the spectrometer, details of the grating fabrication(More)
The purpose of this study was to determine the difference in demands on glenohumeral musculature during unsupported and supported active range-of-motion (AROM) shoulder exercises. Twenty healthy subjects volunteered for this study. Surface or fine-wire bipolar electrodes were applied to the infraspinatus, posterior deltoid, anterior deltoid, pectoralis(More)
The Reflection Grating Spectrometer of the Constellation-X mission has two strong candidate configurations. The first configuration, the in-plane grating (IPG), is a set of reflection gratings similar to those flown on XMM-Newton and has grooves perpendicular to the direction of incident light. In the second configuration, the off-plane grating (OPG), the(More)
High resolution spectra of the active binary Capella (G8 III + G1 III) covering the energy range 0.4-8.0 keV (1.5-30Å) show a large number of emission lines, demonstrating the performance of the HETGS. A preliminary application of plasma diagnostics provides information on coronal temperatures and densities. Lines arising from different elements in a range(More)
