Size distributionA new method for calculating the function (ρ z ) for local electron beam microanalysis is proposed. The method is based on a description of the spatial distribution of the electron beam energy loss at normal incidence on a sample.doi:10.3103/S1062873810070245N. N. Mikheev...
A lack of adequate information concerning these parameters motivated the present study in which activity yields for the reactions 12C(gamma, n)11C, 14N(gamma, n)13N, and 16O(gamma, n)15O were measured as a function of energy of and angle from the electron beam between 16 and 30 MeV ...
of a water drop.Due to the scattering effect,the spread functions were dependent closely on nominal electron beam energy,applicator size and air gap.The calculated and measured doses were within ±5% for standard SSD without insert.Conclusions:The energy spread function of electron pencil beam ...
To investigate the effects of electron beam irradiation on structure and function of hyaluronic acid(HA),HA were irradiated at 5.0,10.0,20.0,40.0,80.0,100.0 and 150.0 kGy by electron beam,respectively,to detect the changes of molecular weight,viscosity,pH,oxidation resistance,ultraviolet spectrum,infr...
In the present study, the effect of electron-beam irradiation on physicochemical and mechanical properties of polypropylene (PP) syringes was studied. Three irradiation doses (30, 60 and 120 kGy) were applied to all samples. Non-irradiated PP syringes were used as control samples. Electron-beam...
The inventive apparatus measures workfunction values using deflection of an electron beam without direct contact of the electron beam with the sample surface. The apparatus, mounted within a vacuum chamber, includes an electron gun, a position sensitive electron detector, and a sample. The sample is...
