Abstract:
     This invention relates to an uneven measurement method for single-ball multi-counter probe. Wherein, arranging three slim column thermal neutron position sensitive counters into a slow-down ball equispacedly and vertical mutually; measuring the distribution of thermal neutron; dividing axially the ball into out-thin-inner-thick some spherical shells unequally in data process, setting the thickness of outermost layer more than 5mm and other layers with thickness by equidifferent values; summating the number of every counter; calculating the opposite response function by a spectrum deconvolution software. The result is very close to the neutron source energy spectrum.
