Characterization of a supersonic molecular beam for charged particle beam profile monitor

H. D. Zhang et al.

Summary: In this study, an experimental method was developed to measure the density and distribution of a supersonic molecular beam used for charged particle beam profile monitoring. The density of the molecular beam ranged from 10(14) to 10(17) molecules/m(3). The vacuum performance of the system using beam-induced fluorescence mode was discussed. The successful measurement of the molecular beam parameters opens up future applications in beam profile monitors for machines such as the LHC and proton therapy accelerators.

A gas curtain beam profile monitor using beam induced fluorescence for high intensity charged particle beams

A. Salehilashkajani et al.

Summary: A minimally invasive transverse beam profile monitor based on supersonic gas curtain technology and beam-induced fluorescence has been developed and demonstrated. It can be used to measure both the profile of the proton beam in the Large Hadron Collider (LHC) and the concentricity of the electron and the proton beams in the LHC hollow electron lens. The performance of such a monitor for a low energy electron beam is discussed in this Letter, paving the way for its wider implementation.

High-intensity beam profile measurement using a gas sheet monitor by beam induced fluorescence detection

Ippei Yamada et al.

Summary: A novel transverse beam profile monitor was developed to visualize a two-dimensional beam-induced fluorescent image using a rarefied gas dynamics technique. A simplified analysis method was developed to reconstruct the beam intensity profile, which was successfully applied in measuring a beam profile at J-PARC 3 MeV H? beam. The system was capable of accurately reconstructing a beam profile from a single shot beam pulse.
