	Since last RuPAC two runs of the Nuclotron operation were performed: in January - March of 2015 and June 2016. Presently we are providing the run, which has been started at the end of October and will be continued up to the end of December. The facility development is aimed to the performance increase for current physical program realization and preparation to the NICA Booster construction and Baryonic Matter at Nuclotron experiment.

THPSC009	Boundary-Value Problem for Elliptic Equation in the Corner Domain in the Numerical Simulation of Magnetic Systems
	R.V. Polyakova, A.D. Kovalenko, E.E. Perepelkin, I.P. Yudin JINR, Dubna, Moscow Region, Russia
	Modern particle accelerators and detectors* contain magnetic systems of complex geometrical configuration. Design and optimization of the systems led to the necessity of solving a nonlinear boundary-value problem of the magnetostatic. The considered region consists of two sub-domains namely: vacuum and ferromagnetic. In view of complexity of magnetic systems, the ferromagnetic/vacuum boundary can be non-smooth, i.e. it includes a corner point that separate two smooth curves belongs to different sub-domains and crossed in the corner point at some angle. A nonlinear differential equation of divergent type in the domain with a corner and the opportunity of existence of solutions with an unlimitedly growing module of gradient in the vicinity of the corner point have been considers in*. A theorem of limitation of the module of gradient of the solution in the vicinity of the corner point in the case of the magnetic permeability satisfying to certain conditions at high fields was proved. An upper estimate of the maximum possible growth of the magnetic field in the corner domain is presented in [4]. The method of designing the differential mesh near the corner domain allowed reducing considerably a relative error of calculating the magnetic field in the considered design problems. Examples of calculating some magnetic systems containing a domain with the corner point are given in [2-4].

	The new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR, Dubna. This complex is assumed to operate using two injectors: the Alvarez-type linac LU-20 as injector of light ions, polarized protons and deuterons and a new linac HILAc - injector of heavy ions beams. Old HV for-injector of the LU-20, which operated from 1974, is replaced by the new RFQ accelerator, which was commissioned in spring 2016. The first Nuclotron technological run with new fore-injector was performed in June 2016. Beams of D⁺ and H²⁺ were successfully injected and accelerated in the Nuclotron ring. Main results of the RFQ commissioning and the first Nuclotron run with new for-injector is discussed in this paper.
