Program, developed jointly with MLIT, received state registration certificate A program for analyzing cyclotron electromagnetic field maps in closed equilibrium orbits, CORD (Closed ORbit Dynamics), was created by Taisia Karamysheva, a senior researcher of the MLIT Sector of Methods for Solving Mathematical Physics Problems, in collaboration with colleagues from DLNP JINR. The program received a certificate of state registration of a computer program in the Russian Federation on 9 April 2026. The authors of the program are staff members of the DLNP Scientific and Experimental Department of New Accelerators: Oleg Karamyshev, Ivan Lyapin, Vladimir Malinin, Dmitry Popov, as well as Taisia Karamysheva (MLIT). Abstract: The program is designed to calculate the characteristics of cyclotron electromagnetic field maps. It determines the mean magnetic field, flutter, lower harmonics and searches for closed equilibrium orbits. The program can be used to calculate betatron frequencies, particle revolution frequencies, and deviations of the mean field from the isochronous condition. Program’s functionality: CORD calculates the distribution of accelerating voltage along the radius using a map of the electromagnetic field of the accelerating system and analyzes the phase motion of equilibrium particles using data from both magnetic and accelerating fields. Computer type: PC with Intel, AMD, x32, or x64 processors OS: Windows 10 Programming language: MATLAB Computer program size: 40 KB.
