TUCBMH01	Optimum Luminosity of Proton-Ion Collider	32
	I.N. Meshkov JINR, Dubna, Moscow Region, Russia
	The problem of optimal parameters of proton-ion collider is considered. It is shown that the maximum luminosity of the p-i collider is achieved when the Laslett tune shifts of the ion and proton bunches are equal. As an example, the luminosity of the NICA collider in proton-ion collision mode is presented. This calculations are based on the results of the article. I.N.Meshkov. Luminosity of a Collider with Asymmetric Beams, Phys. Part. Nucl. Lett., 2018, 15, No. 5, pp. 506-509.

	The magnetic field correction systems in the optimized lattice of the NICA collider are considered. The dipole, normal and skew quadrupoles, sextupole and octupole additional windings are placed in the corrector elements to compensate separatly the alignment errors, betatron tune shifts, betatron coupling, chromaticity and non-linear fields. The overall correction effect should provide the required beam and luminosity lifetime of the collider.

TUPSA08	Stability of Charged Particle Motion in a Storage Ring With Focusing by a Longitudinal Magnetic Field	158
	S.A. Melnikov, I.N. Meshkov JINR, Dubna, Moscow Region, Russia I.N. Meshkov Saint Petersburg State University, Saint Petersburg, Russia
	The goal of the presented research is analyse an influence of the solenoidal magnetic field perturbations on the dynamics of charged particles in a storage ring with a longitudinal magnetic field LEPTA. The Low Energy Particle Toroidal Accumulator, constructed in the VP Dzhelepov Laboratory of Nuclear Problems, JINR, is designed for generating a directed orthopositronium flux, which is formed as a result of recombination of positrons circulating in the LEPTA ring with a single-turn electron beam of electron cooling system. To provide a long-term stability of the circulating positron a helix quadrupole magnetic field is formed in one of the straight sections of the ring. The report presents an optical transformation matrix for the LEPTA ring, obtained on the basis of the solution of the motion equation in WKB-approximation. The matrix of the region of the solenoid field pertubations is included in the Full Transformation Matrix (FTM) of the LEPTA ring. The program built in Mathcad for this matrix, made it possible to study the multi-turn stability of the particle motion in the LEPTA ring. The results are presented in the report.

Meshkov Saint Petersburg State University, Saint Petersburg, Russia
	The report proposes the scheme and design of the setup for formation a continuous monochromatic positron flux with controlled time of arrival at the target, independent of the injection time in a limited time interval. The setup is designed to perform experiments to measure the positron lifetime with the positron annihilation spectroscopy method (Positron Annihilation Lifetime Spectroscopy - PALS). PALS method allows to distinguish defect types in the materials. It is possible to vary the positron energy in the present version of the setup that allows us to analyze the distribution of defects along the depth of the sample. The scheme of periodic RF voltage generation of a given form and measurement of the positron lifetime, is discussed.
