Area of Science:

  • Materials Science
  • Instrumentation
  • Physics

Background:

  • Synchrotron radiation facilities require precise beam monitoring.
  • Existing beamstop technologies can be complex or expensive.

Purpose of the Study:

  • To develop a versatile beamstop with an integrated sensor.
