Area of Science:

  • * Physics
  • * Materials Science
  • * Chemistry

Background:

  • * Synchrotron radiation sources are crucial for advanced experiments.
  • * Time-resolved pump-probe experiments require precisely controlled X-ray pulses.
  • * Existing chopper systems may have limitations in pulse duration and heat management.

Purpose of the Study:

  • * To describe a novel chopper system for time-resolved pump-probe experiments.
  • * To enhance the capabilities of synchrotron X-ray sources for ultrafast studies.
  • * To improve the time resolution and experimental flexibility.

Main Methods:

  • * Development and implementation of a three-part chopper system: a heatload chopper, a high-speed chopper, and a millisecond shutter.
  • * Installation of the system on beamline ID09B at the European Synchrotron Radiation Facility.
  • * Design of a new rotor for the high-speed chopper with single (100 ps) and long (10 µs) pulse options.
  • * Integration of a water-cooled heatload chopper to manage thermal load.

Main Results:

  • * The chopper system produces X-ray pulses as short as 200 ns with repetition rates from 0 to 3 kHz.
  • * The high-speed chopper can isolate single 100 ps X-ray pulses for high time resolution.
  • * The heatload chopper effectively absorbs 95% of incoming power, protecting the high-speed chopper.
  • * The new rotor provides versatile pulse options for different experimental needs.

Conclusions:

  • * The described chopper system significantly advances time-resolved pump-probe capabilities at synchrotrons.
  • * It enables higher time resolution and greater experimental control for ultrafast laser-X-ray experiments.
  • * The system's design addresses heatload challenges, ensuring reliable operation.
