A special fast ionization gauge is developed to measure the neutral gas pressure in the main chamber and the divertor chamber of the HL-2A tokamak during discharges in order to research on particle behaviors, and to control the neutral gas pressure actively in the divertor chamber to further obtain radiation or detached divertor discharges
