Studying of energy and spatial distribution of fast ions is the principal problem in GDT-based neutron source project. The analyser described here was used to solve this problem. It includes active target, stripping chamber, electrostatic capacitor and microchannel plate with amplifiers. Fast ions are neutralizing on active target (hydrogen beam). These particles go through collimation system, get recharged in the stripping chamber for further separation on energies in the electrostatic analyser and finally falls to MCP. Then signals are amplified and registered.
