This work determines whether hyperspectral imaging is suitable for discriminating ore from waste at the point of excavation. A prototype scanning system was developed for this study. This system combined hyperspectral cameras and a three-dimensional

In the wavelength regime between 60 and 300 microns there are a number of atomic and molecular emission lines that are key diagnostic probes of the interstellar medium. These include transitions of [CII], [NII], [OI], HD, H_2D^+, OH, CO, and H_2O, so

We describe a technique to measure the spatial extent and magnitude of gain depression in the quiescent pores surrounding an active region of an MCP and present preliminary results. We find that significant gain depression occurs up to 1.5 mm from th

We describe a novel, charge centroiding, position readout, the spiral anode (SPAN) which combines excellent spatial resolution with very high count rate performance. SPAN is a planar structure of six electrically isolated electrodes. The ratio of the

On future astronomical instruments for the soft x-ray to FUV, stray light may be a significant cause of background events. Currently, we are engaged in an ongoing program to identify materials that are suitable for use as low- reflectance surfaces in
