Abstract: FIELD: high-voltage pulse engineering and electrophysics technologies. SUBSTANCE: method provides for stage-by-stage peaking of pulse front by using Marx generator circuit; pulses are shaped in generator power conductor and their amplitude grows due to pulses supplied to pulse generator trigger gap from trigger generator over long broad-band uniform transmission line having following parameters: U vpi ≥3•U st ,t i.nt. ≤10 -9 s, where U vpi  is amplitude of voltage pulse initiating generator discharge and supplied from trigger device; U st  is static breakdown voltage of trigger gap; t i.r.t.  is rise time of initiating voltage pulse; shaping voltage pulse is supplied sequentially to gap of stages starting from first one. Stage-by-stage peaking is expressed by set of mathematical relations showing that rise time of pulse across load depends only on switching time of each spark gap of generator and does not depend on generator electric length. Pulse voltage generator is built around Marx circuit and broad-bend long uniform transmission line between trigger device and trigger gap, and power conductor in the form of broad-band uniform long line with distributed parameters. The following conditions are satisfied:  , where k is stage number; h d  is distance between forward and reverse current conductors; C 0  is light speed in vacuum; ε c.d.c.  is relative dielectric constant of insulation in power conductor; N is number of stages in generator; t t.(k-1)  is rise time of electromagnetic pulse upon operation of (k-1)-st stage gap (at k-1=0 of trigger gap); t tr.(k-1)  is transit time of electromagnetic pulse through power conductor between gaps of (k-1)-set and k-th stages. Discharge time constant of capacitor in each stage is chosen mush higher than that upon operation of given stage gap but not higher than five-fold transit time of electromagnetic pulse over transmission line. Rise time of initiating voltage pulse is not higher that two-fold transit time over transmission line but lower than rise time of pulse upon operation of gap of any stage. Charge time constant of interelectrode capacitor of gap in any stage and that of any trigger gap is much lower than rise of pulse upon operation of respective stage gap or trigger gap. Open circuit length in forward current conductor for stage storage capacitor, including dielectric constant of storage capacitor insulation, is lower than distance between forward and reverse current conductors, including dielectric constant of power conductor insulation. EFFECT: provision for stage-by-stage peaking of pulse rise time with stage-by-stage growth of shaped pulse amplitude. 2 cl, 3 dwg
