PM3 Dipole PGM variable polarisation

PM3

"PM3 merges the developments of the former BESSY I SX700 III monochromator for elliptically polarized VUV radiation and of BESSY II collimated plane grating monochromators. This way it is possible to achieve circular polarization from a BESSY II dipole in the range 20 – 2000 eV with high photon flux, high energy resolution and high stability." http://dx.doi.org/10.17815/jlsrf-2-73
