Abstract

For multisectional traveling wave linear electron accelerators, the acceleration of positrons from an electron-bombarded intersectional converter target is considered by comparison of the model with an experiment. For the accelerated positrons and their energy spectra, the dependence of maxima of these spectra on the initial phase shift of a microwave (which accelerates the positrons) and on the energy of accelerated positrons and the phase distributions of these positrons are obtained. The spectra of the initial positron energies are found, which are essential in obtaining the accelerated positron current at the maximum of their spectrum. To study giant resonances in atomic nuclei, the efficiencies of obtaining positrons with and without their acceleration at electron LINACs are compared.
