SXS Gang?

The X-ray telescope and detectors on Astro-H will be far apart. Indeed, focussing light onto the detectors will almost be like having someone apply eye drops from the second floor! A special system, known as “CAMS”, has been designed to ensure that the telescope and the detectors are always properly aligned. In this system, a laser beam located near the telescope is directed towards (but not directly at!) the detectors, where it is reflected from a mirror onto another detector. In this way, the degree of alignment of the telescope and detectors can be measured. Today CAMS experiments will be conducted, so members of the SXS team have donned goggles as they prepare the laser for the experiment. Good luck to the SXS Gang!
