Estimates of the dependence of the fusion neutron yield on the initial plasma density and temperature in fast pinches

The neutron generation by hot, dense, and fast $Z$- and $\Theta$-pinch plasma with the parameters achievable at the present development stage of high-power pulsed technology has been calculated. It has been proposed to use a hot plasma with a high density of 10$^{17}$ cm$^{-3}$ as an initial state for subsequent compression by $Z$- and $\Theta$-pinches to achieve the conditions necessary for fusion reactions. Such plasma can be obtained using high-power pulsed plasma accelerators.
