Contribution

It provides the first simulation-based analysis of Smith-Purcell radiation for proton beam profile diagnostics, extending its application beyond electron beams.

Findings

Simulations indicate feasible yield levels for proton beam measurements.

Smith-Purcell radiation can be a non-intercepting diagnostic tool for high current proton beams.

Potential for developing new beam diagnostics based on the findings.

Abstract

The use of Smith-Purcell radiation to measure electrons longitudinal profiles has been demonstrated at several facilities in the picosecond and sub-picosecond range. There is a strong interest for the development of non intercepting longitudinal profile diagnostics for high current proton beams. We present here results of simulations on the expected yield of longitudinal profile monitors using Smith-Purcell radiation for such proton beams.
