An Overhanging Absorber for TES X-ray Focal Planes

Author(s)
James P. Hays-Wehle, Peter J. Lowell, Daniel R. Schmidt, Daniel S. Swetz, Joel N. Ullom
In order to improve pixel count and collecting area, future TES x-ray focal planes require pixels with both a higher coverage of the active area and

A Thin-Film Cryotron Suitable For Use as an Ultra-Low-Temperature Switch
