SM Optical Description
Variable polarization: arbitrary linear
150-2000eV, circular- 100-1000eV
Infinity corrected PGM: STXM at long
arm branch (preserved brightness),
PEEM (exchangeable) on short

Nominal energy resolving power 3000,
may be increased till 7000
Intensity on sample: STXM-108ph/s at
40nm, PEEM-1012ph/s in f40m
Stable operation even for CLS 2005 ebeam parameters

Ray-tracing shows that the XAFS focus is ~1050 m
horizontal (FWHM) x ~257 m vertical (FWHM) in
size. The Kirkpatrick-Baez mirror pair reduces this
down to ~[14-19] m
horizontal (FWHM) x [6-9] m vertical (FWHM), using
bent elliptical cylinders.
Wiggler Brilliance
DTJ Note: This is from the first hybrid design concept, total power
SR there would have been 23 kW. Gave up and switched to
Superconducting design. The new design is at least another factor
of 2 better yet half the total SR power. Smaller SR horizontal fan of
course.
