  1. Dual Mirror Optical System for use with Grazing Incidence Spectrograph Ryan Anderson 16 March 2002 Brigham Young University

  2. Special Thanks • Dr. Steven Turley (BYU) • Dr. Aleksander Shevelko (Lebdev) • Wes Lifferth (BYU) • Matthew Crookston • Raymond Rios

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

  4. GIM-S • Grazing Incidence Monochromator-Spectrograph • Lebdev Institute • Constant angle of deviation • Spectral Resolution

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

  6. SETUP 2 SETUP 1 Radius dependence on dimensions Dual mirror system

  7. Dimensions

  8. Ordering the mirrors • Tolerance • Spherical – 1970 +/- 5 mm • Cylindrical – 14 +/- 0.1 mm • Size • “Tweaking”

  9. Manufacturing • Under Vacuum • Adjustability • Size • Attachable

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