  The influence of the inhomogeneous magnetic field on the shape of nuclear induction signals is analyzed. The most frequent five of magnetic field distributions: Lorentz, Gaussian, exponential, triangular and ideal “square”- are described. Nonideal "square" distributions that have finite duration pulse edges variable by Lorentz, Gaussian, exponential and triangular dependences are considered. The signal change as a result of placing of nuclear spins under the constant gradient magnetic field is studied. All results have been found in the analytical form taking into an account the magnetic screening effect of atomic nuclei.

  User interface in the diagnostic system of extracted beams is described. It was developed under Linux operating system on the personal computers used as workstations. The considered program tools provide: - the representation on operator consoles (workstations) information about beam profiles, intensity, displacement, root-mean-square error etc. in different forms; - the dynamic adjustment of the diagnostic system; - web presentation of the currrent information about the extracted beams; - data transfer to physical setups; - special beam characteristics calculation by the profilometer individual units data (for research purposes); - data archiving and web facilities for data viewing.

  The Cryogenic and Vacuum System for OKA experimental complex requires reliable, fast and convenient program facilities for cryogenic data analysis – temperatures of cryogenic components, liquid helium levels, helium mass flow rates. The appropriate software service has been build on the base of common solution using MS SQL-server for historical data manipulation and IHEP Zerver for online data representation. Accordingly two computers are used to store and maintain cryogenic data which gives users two ways of data displaying. The archive view software (graphs, tables, correlation analysis) has been build with help of NI Developer Suit Core. The mimic panels software uses to display the live data. The mimic panels could be viewed through web-interface using Java applets, this is original software written in IHEP.

  Our work presents the analysis of methodology detecting the leaks locations in the vacuum chamber of the proton synchrotron U-70. We present the results of solutions of differential equations for the pressure of the air components allowing to determine the leak location. The pressure is calculated by the measurements of the sputter-ion pumps discharge current.
