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.
