Ion-Optics Systems Of Multiply Charged High-Energy Ions For High Emittance Beams

INTRODUCTION The development of technological processes based on the use of beams of protons and heavy ions accelerated to energies of 1 to 10 Mev/nucleon, as well as the use of such beams for determining the elemental composition of samples and elemental concentration profiles have stimulated the development of ion-optics systems that form high-energy beams of various configurations. Quadrupole magnetic lenses (QML) are the heart of such systems now. The literature on the basic principles of QML calculation and operation is quite extensive (see, for example, [1,2]). The chief lines of investigations now are optimization of experiments and widening the scope of exploiting of accelerators with high emittance ion beams. Both of these problems have risen during creation of microprobe and nuclear track membrane equipment for our cyclotron. An analysis shows that the most convenient ion-optic systems that solves these problems are triplet or quadruplet of QMLs. We have derived a
