Abstract
A new method for determining the dimension of a hot spot in hot dense plasmas is presented. A time-integrated pin-hole camera was used and t he experimental densitograms from the pin-hole pictures of hot spots w ere computationally simulated using a specific source intensity distri bution function. The method was used in plasma focus DPF-78. The best estimate for the hot spot size is the effective size, the FWHM of the intensity distribution function. The effective radius of hot spots in DPF-78 varies in the range 30-106 mu m.
