A two-section air-filled ionization chamber operating at normal pressure is used as a detector. It consists of two ionization chambers with different interelectrode distances combined into one module. In different structural versions of the module, the direction of the proton beam can be either perpendicular or parallel to the electrodes of the chamber. The number of protons passing through the detector is calculated using the developed algorithm in real time. Experimental data on the total number of protons and the average value of the proton flux is recorded by the electronic measuring stand. PB - JACoW Publishing CP - Geneva, Switzerland ER -
