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.

A new driver of the fast capillary discharge has been 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 arrangement substantially simplifies the experiments (adjustment, monitoring, applications). The designed apparatus is capable of reaching the discharge current of the order of 120 kA and the discharge current rise time 2.9×1012 A/s, which is sufficient for the investigation of amplification in non-traditional electronic transitions.
