Xx. Wang et H. Schmidt, DETERMINATION OF THE EFFECTIVE SIZE OF A HOT-SPOT IN HOT DENSE-PLASMAS, Plasma sources science & technology, 5(3), 1996, pp. 573-577
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.
