A Pinhole Camera for SPEAR 2

Technical Report ·
DOI:https://doi.org/10.2172/800080· OSTI ID:800080
A new pinhole camera system has been installed on Spear 2 to measure its vertical emittance. The hard X-rays from a bending magnet source point are imaged on a phosphor screen through a 30 um x 25 um pinhole aperture. The resolution of the system for 8 keV photons is limited to 31.2 um by Fraunhoffer diffraction and is much smaller than the 340 um FWHM vertical beam size corresponding to 0.9% vertical coupling. Measurements are presented. Optimal pinhole location and hole size are discussed.
