© 2022 National Research Center Kurchatov Institute. All rights reserved.In the plasma focus chamber of the PF-MOL installation, a pulse valve allows to obtain an inhomogeneous density of the working gas. In the combined mode of operation (stationary for start-up and additional gases injection), it is possible to use different gases together in one start-up. The installation has a capacitive source with a maximum current of 750 kA. The chamber houses a system of magnetic probes. At currents of 700 kA in the normal mode of stationary deuterium filling, the neutron yield Ynis (4-5)109per pulse. The maxi-mum output Yn= 1,2·1010was obtained with additional pulsed deuterium recharge of the focusing area of the current shell. Experiments have been carried out with a helium current shell compressing injected deuterium. At a current of 530 kA, the output Yn~ 2·109was re-producibly recorded. Tests indicating the absence of a helium impurity in the deuterium pinch plasma were carried out.
