All commercial electron spin polarimeters work in single channel mode, which is the bottleneck of researches by spin-resolved photoelectron spectroscopy. By adopting the time inversion antisymmetry of the magnetic fie...
A compact high precision eight-axis automatism and two-axis manual soft-ray polarimeter with a multi- layer has been designed, constructed, and installed in 3WlB at the Beijing Synchrotron Radiation Facility (BSRF)....
The nucleon excitation spectrum remains poorly known, with the masses, widths, EM couplings and even existence of many states not well established. A program of experiments using meson photoproduction off the nucleon ...
