  1. Detection Scheme of Single Shot Time Resolved X-ray Emission Spectroscopy of Chemical Dynamics at LCLS Kathleen R. Geyer August 12, 2010 Mentor: Dennis Nordlund

  2. UHV End Station • Soft X-rays: 0.12 to • 12 KeV • PES, XAS, and XES

  3. How it Works

  4. How it works

  5. Ideal Smile

  6. Ideal Spectrum

  7. Adimec Opal-1000m/Q High Speed CCD Camera 1 Megapixel resolution

  8. Camera Settings • Focus • Field of view • Minimizing Background • FPS • Exposure time • Gain Settings

  9. Gain Setting Gain = Number of electrons per pixel/number of counts per pixel (ADUs)

  10. SSRL Run: Smile

  11. SSRL Smile Ideal Smile

  12. SSRL Run: Spectrum Raw Data Removed Background

  13. Conclusion Averaging of images using background discriminator does not work Next Step: Blob finder program
