摘要：

In the present work, we report an experimental method to measure the density and distribution of a supersonic molecular beam used for charged particle beam profile monitoring. The density of the molecular beam used in this monitor was in the range of 10(14)-10(17) molecules/m(3). The vacuum performance of such a system using beam-induced fluorescence mode was discussed. The successful measurement of the molecular beam parameters paves the way for future applications in beam profile monitors for machines such as the LHC and proton therapy accelerators.
