Saturation regime of THz generation in nonlinear crystals by pumps with arbitrary spectral modulations / Curcio, A (CERN) ; Petrarca, M (Rome U.)
A self-consistent analytic formalism of the description of saturation effects in optical rectification is provided. It is shown that a nonlinear absorption term arises from this process that is dominant over two-photon absorption, deriving instead from the nonlinear susceptibility of the third order. [...]

Studying the atomic gyroscope magnetic shield residual magnetization by comparing parametric resonance signals / Chalkov, V V (SED-SPb, St. Petersburg) ; Shevchenko, A N (SED-SPb, St. Petersburg)
The paper presents an algorithm for measuring the residual magnetic field in the magnetic shield of a quantum rotation sensor, which is based on the analysis of cesium parametric resonance signal. The effect of the residual magnetic field in the magnetic shield of the passive shielding system of an atomic gyroscope on its performance is investigated. [...]

Underwater radiated noise model of marine object / Prokopovich, V V (SED-SPb, St. Petersburg) ; Shafranyuk, A V (SED-SPb, St. Petersburg)
The paper is devoted to the developing a comprehensive model for underwater radiated noise of marine object in order to model and simulate sonar systems. Many works present underwater radiated noise models, but as a rule, they consider either one of the noise components in order to develop algorithms for the corresponding sonar operation mode, or one of the noise sources in order to design ship parts and assemblies [...]

Electro-mechanical modelling of the iron force distribution with superconducting magnets / Martins Araujo, D (CERN) ; Ferracin, P (CERN) ; Testoni, P (Fusion for Energy, Barcelona)
This paper shows the influence of the local magnetic forces on the mechanical analysis of a superconducting dipole magnet employing Nb3Sn technology. On high field magnets, the iron yoke has several functions: (1) magnetically, it increases the magnetic field in the bore and it has a shielding function; (2) mechanically, iron helps on the coil pre-load, transferring the mechanical forces provided by the external support structure. [...]
