Overview

Development of a laser-based system measures beam profiles in the PIP-II linac, indicating improved monitoring for superconducting cavities.

Key Points

  • To design a non-invasive laser-based monitoring system for beam profiles in the PIP-II superconducting H- linac.
  • Developed a system using non-invasive laser monitors known as laserwires.
  • Utilized photoionization to obtain accurate beam profiles.
  • Designed an optical transport line and 13 individual laserwire stations.
  • Implemented pulsed laser technology with feedback and timing controls.
  • Outlined a signal detection system for effective profile measurement.
  • Successfully designed the laserwire system to monitor beam profiles.
  • The system aims to limit potential damage to the superconducting RF cavities.
  • Demonstrated the feasibility of using picosecond pulsed lasers for beam monitoring.
