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 (preserve flux)  Nominal energy resolving power 3000, may be increased till 7000  Intensity on sample: STXM-10 8 ph/s at 40nm, PEEM-10 12 ph/s in f 40 m  Stable operation even for CLS 2005 e beam parameters

Micro-XAFS

PI De-Tong Jiang: [email protected]

Superconducting Wiggler Parameters: l m = 0.033 m Magnet Period Length N = 35.5

Number of Periods B = 1.9 T K = 5.91

Magnetic Field K Parameter Front End Aperture: 1 mrad (H) x 0.24 mrad (V) 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.
