[en] Possibilities of spectrometric experiments with ''superthin'' internal targets and with circulating beams of charged particles at storage rings with electron cooling are described. The internal targets can be made as thin films, filaments, gas jets, steam jets, heavy-current beams of low energy ions. Targets in the form of polarized atom flows are especially promising for polarization experiments. Evaluations of parameters of a spectrometric storage ring with a cooled beam are presented to illustrate the method of polarized targets and beams. Prospects of the electron cooling method for high-resolution spectroscopy are disclosed

[en] A summary is given of the polarized beam/target facilities available at TRIUMF, LANL, BNL, FNAL, SCC, Bates, CEBAF, and SLAC

[en] The scheme of antihydrogen beam generation is proposed. Two storage rings should be used for effective generation of antihydrogen - an antiproton ring and small additional one for storing and cooling of positrons. This scheme has advantage compared with that was discussed before due to use of a longitudinal magnetic field for focusing system of positron ring with a positron source, what is immersed in this field. The electron cooling of positrons is essential part of the project. The Low Energy Antiproton Ring (LEAR) at CERN is chosen as a basic machine for the idea demonstration and all the numerical applications are made for it. The rate of antihydrogen generation is limited in the case discussed here by positron source intensity. The simplest version of this scheme permits to achieve the rate about 1·10⁴ fast (50 MeV) atom/sec and 25 slow (0.5 MeV) ones. Simultaneously such a scheme is a generator of orthopositronium with productivity about 1·10⁴ and 60 'atoms'/sec, correspondingly. The particle dynamics in the positron storage ring is considered. 15 refs., 6 figs., 4 tabs

[en] In electron cooling, the area of the electron beam can be regarded as a solid, continuous charge distribution with which one associates a rigid, continuous field. The effect of this field on the stability of the motion of protons or anti protons in the accelerated beam is considered

[en] The possibility of increased efficiency in bunching of initially multienergetic relativistic and ultrarelativistic charged particles by use of magnetic paths is demonstrated: the amplitude of the fundamental can be increased to a level of 1.9I₀ or more, and the amplitude of the tenth harmonic to 1.8I₀ or more. In the case of closed magnetic paths, solitary clusters of high density and compact length can be obtained, and several sequential open paths permit production of continuous flows or sequences of such bunches. High efficiency is achieved by using high values of primary bunching parameters in combination with increasing energy modulation depth in the bunching process

[en] Optical issues for electron cooling in the Recycler are discussed. An optimal value of the antiproton beta-function depends on the cooling purposes (longitudinal or transverse), on the antiproton emittances and the energy spread. A proposal is suggested for the optimal optics at the so-called SS30HB interval in the Recycler, where electron cooling is supposed to be applied. Both electron cooling and the phase trombone requirements are taken into account. The electron optic scheme is also presented
