Summary

This study enhances electron/ion imaging by integrating an event-driven camera (Tpx3Cam) and high-speed digitizer. This boosts the system's event rate to nearly 1 million hits per second for precise 3D imaging.

Area of Science:

  • Physics
  • Chemistry
  • Instrumentation

Background:

  • A previous camera-based 3D imaging system offered excellent time-of-flight (TOF) resolution and multi-hit capability for electron/ion detection.
  • Further improvements in event rate were sought to enhance the system's performance.

Purpose of the Study:

  • To improve the event rate of a 3D electron/ion imaging system.
  • To integrate advanced detection technologies for higher data acquisition speeds.

Main Methods:

  • Incorporated an event-driven camera, Tpx3Cam, for precise 2D electron position detection.
  • Utilized a high-speed digitizer to achieve accurate (∼30 ps) TOF measurements for each event.

Main Results:

  • Achieved a significant increase in the system's event rate, approaching 1 million hits per second.
  • Maintained highly accurate TOF information (∼30 ps) at the enhanced rate.

Conclusions:

  • The upgraded system demonstrates a substantially improved event rate for 3D electron/ion imaging.
  • The integration of Tpx3Cam and high-speed digitization enables faster and more precise particle detection.
