Improved Response of Geiger Muller Detectors

Computer non-iterative data acquisition of particle trajectory in a spark chamber

“…The cham ber with ca pac i tors is filled with a mix ture of neon and he lium. The mix ture is on at a higher than at mo spheric pres sure and slowly cir cu lates among the plates [9][10][11][12][13].…”

Application of an electronegative gas as a third component of the working gas in the Geiger-Mueller counter

“…Math e mat i cal mod el ling of the elec tri cal break down im plies knowl edge of el e mentary pro cesses in a gas, de scribed by ion iz ing co ef ficients: a -num ber of free elec trons gen er ated per unit of the path crossed in the di rec tion of the elec tric field; h -the num ber of elec trons af fected by the electronegative mol e cules per unit of path in the di rec tion of the elec tric field, g -the num ber of free elec trons gen erated for each pri mary av a lanche. The ion iza tion co effi cients do not have a con stant value but they change de pend ing on the elec tric field and the pres sure [8,9].…”

Lifetime characteristics of Gaiger-Muller counters

“…Based on the se lected quantiles of those dis tri bu tions, a so-called life time char ac ter istic can be con structed. Ex pe ri ence has shown that the life time char ac ter is tic forms a straight line on a dou ble log a rith mic scale [10][11][12]. If the con fi dence in ter vals of the used quantiles are known, they can be transferred to the life time char ac ter is tic.…”
