FIELD: physics; nuclear. ^ SUBSTANCE: invention concerns exploration and detection of the latent weights or objects with radio-activity use, specifically to design of power supply circuits of pulse neutron generators. The scheme of the pulse neutron generator is executed in the form of the module from blocks of electronics, switching and the block of a neutron tube connected in series. The electronics block contains the power supply filter, the scheme of power-up/deenergising and the scheme of forming of a control pulse. The switching block contains a step-up transformer with rectifiers of the power supply of switching units and a neutron tube, the scheme of forming of a commutator initiation pulse, a charging voltage divider in reaction circuits and the commutator. The block of a neutron tube contains the scheme of forming of an accelerating impulse of an electrical pressure on a neutron tube, a power supply circuit of an ionic source of a neutron tube, the scheme of forming of a neutron tube initiation pulse and a neutron tube. ^ EFFECT: increase of reliability, stability and compactness. ^ 4 cl, 2 dwg |
