A new current-measuring system enables highly sensitive X-ray beam-position monitors (XBPMs). This system achieved precise beam position measurements, crucial for advanced synchrotron applications.

Area of Science:

  • Synchrotron Radiation Science
  • Particle Accelerator Technology
  • Instrumentation and Measurement

Background:

  • High-precision X-ray beam-position monitoring is essential for optimizing synchrotron light sources.
  • Existing current-measuring systems often lack the sensitivity required for advanced beam diagnostics.

Purpose of the Study:

  • To design and implement a sensitive current-measuring system for constructing a highly sensitive X-ray beam-position monitor (XBPM).
  • To evaluate the performance of the developed XBPM system during beamline commissioning.

Main Methods:

  • A novel current-voltage (I/V) converter capable of measuring currents from 0.1 nA to 10 mA was designed.
  • The I/V converter was integrated into the signal processing system of the XBPM.
  • The complete XBPM system underwent testing and validation during beamline commissioning.

Main Results:

  • The developed XBPM system demonstrated high sensitivity and accuracy.
  • Beam-position data achieved standard deviations of approximately 3 micrometers for the bending-magnet beamline.
  • For the insertion-device beamline, data showed standard deviations of approximately 3 micrometers (x-axis) and 1 micrometer (y-axis).

Conclusions:

  • The designed current-measuring system and integrated XBPM are effective for precise beam-position monitoring.
  • The system's performance meets the stringent requirements for modern synchrotron beamlines.
  • This advancement contributes to improved experimental capabilities at synchrotron facilities.
