Квадрупольная ионная ловушка Пауля в комплексе оптической спектроскопии многозарядных ионов тория для разработки ядерного стандарта частоты

A laboratory prototype of a complex of optical spectroscopy of multiple-charged thorium ions for development of nuclear frequency standard is presented, as well as preliminary experimental research on generation of single-, double-, and triple-charged ions from solid compounds of thorium nitrate (IV) by electron beam evaporation are carried out. It is shown that the ratio of triple- and double-charged ions to single-charged ions produced by this technique exceeds values obtained by the laser ablation method in laboratories of the U.S. and Germany. Electron beam evaporation technique is the basis of the developed complex of optical high-resolution spectroscopy.
