Interaction of the superconducting condensate with deformations of the crystal lattice is formulated assuming the electrostatic potential of Bernoulli type and the effect of strain on material parameters. In the isotropic approximation it is shown that within the Ginzburg-Landau theory both contributions can be recast into the local but non-linear interaction term of the free energy.Comment: 6 page

Design of a new driver for fast capillary discharge

A new driver of the fast capillary discharge is designed. It consists of the Marx generator and radial Blumline pulse forming line. Such a geometry enables axial access to both capillary ends ("transparent capillary"). This substantially simplifies the experiments (adjustment, monitoring, applications). The designed apparatus is capable to reach the discharge current above 90 kA and the discharge current rise time 4x1012 A/s, which is sufficient for investigation of amplification in non-traditional electronic transitions

Investigation of corpuscular emission from the Prague Capillary Pinch

The paper presents results of preliminary measurements of the corpuscular radiation from fast z-pinch discharges, which were performed at the Prague Capillary Pinch facility within a frame of the Czech-Polish scientific collaboration programme. Time-integrated measurements were performed by means of a pinhole camera, equipped with nuclear track detectors of the CR-39 type. In order to perform time-resolved measurements the use was made of a single Faraday-type collector and a double-cup system. It was demonstrated that the fast capillary discharges can emit not only pulses of intense visible radiation and soft X-rays, but also pulses of the corpuscular radiation. An optical analysis of the particle tracks was performed. The particle flux at a distance of 20 cm from the collimator outlet was estimated to be 3.5×107 particles/cm2
