  1. Optimization of the LCLS Single Pulse Shutter Research Advisor: Dr. FRITZ Participant: Solomon Adera

  2. What is a Pulse Picker? separates a single pulse. reduces the repetition rate of the LCLS pulse train from 120 Hz (source) to 0 – 10 Hz. should be aligned with high precision with the incoming beam.

  3. Static aperture Dynamic aperture Exposure time Opening delay Inclination

  4. Typical displacement vs. time plot

  5. 120 Hz X-ray source The purpose of this project is dynamic aperture to ~ 4 mm open/close window time ~ 12 ms

  6. Does freq. affect to and aperture?

  7. LCLS’s desired result

  8. Effect of increasing aperture

  9. Solution 1:use stronger magnet.

  10. Solution 2:Increasing input voltage duration

  11. Solution 3:employing a damping element
