Energy Range | 4.6 - 40 [eV] |
---|---|
Type | 4-m-long normal incidence monochromator (NIM) with a constant included angle of 5° |
Resolving Power | 3 * 10-5 [deltaE/E] @ 9 [eV] |
Number Of Gratings | 3 |
Grating Type | 1) Al/MgF2 grating with 1500 l/mm, laminar profile, photon energy range 4.6-13 eV. 2) SiC grating with 3000 l/mm, laminar profile, photon energy range 15-19 eV. 3) Pt grating with 3000 l/mm, blaze profile, photon energy range 14-40 eV. |
