Miniature Pencil-Beam X-ray Collimator

Completed Technology Project

Project Introduction

X-ray mirrors used on current astrophysical satellites have sub-arcmin angular resolution and a physical diameter about tens of cm. This poses a serious practical problem for their calibration, which requires a parallel incident X-ray beam to approximate a celestial point source at infinite distance.
