Capillary Discharge Controllable XUV source Controllable XUV source Max 240 kV discharge, ns pulse Max 240 kV discharge, ns pulse Plasma: shape, density, temperature Plasma: shape, density, temperature

GIM-S  Grazing Incidence Monochromator-Spectrograph  Lebdev Institute  Constant angle of deviation  Spectral Resolution

Why use mirrors?  Gather more light  Focus in both planes  Tangential Spectral Resolution Spectral Resolution  Sagittal Spatial Resolution Spatial Resolution After Grating-Film Entrance Slit - GIMS Capillary Sag Tan

Dual mirror system Radius dependence on dimensions SETUP 1SETUP 2

Dimensions Spherical Mirror 1970 mm Cylindrical Mirror 13.9 mm Capillary to Spherical 120 mm Spherical to Cylindrical 60 mm Cylindrical to GIMS 60.5 mm Spherical grazing angle 3.5 degrees Cylindrical grazing angle 3.5 degrees

Ordering the mirrors  Tolerance –Spherical – /- 5 mm –Cylindrical – 14 +/- 0.1 mm –Size  “Tweaking”

Manufacturing  Under Vacuum  Adjustability  Size  Attachable

Future plans  Build it  Hook it all up to the capillary  Differential Pumping System  Adjustability???  Soft x-ray laser (source/gain media)
