文摘

It has been theoretically and experimentally shown that, using stepwise rotation of a multielectrode free-air ionization chamber to measure the parameters of a pulsed proton beam, it is possible to substantially increase the accuracy in determining both the centroid position of the beam cross section, as well as the transverse distribution of the dose produced by the beam. The linear operation modes of the chambers are identified and the system characteristics are investigated. The inaccuracy in determining the centroid position of the beam cross section is
