| Abstract(in English) | We have studied normal-distribution-function-shaped Josephson tunnel junctions for STJ (superconducting tunnel junction) photon detector applications. By employing a normal-distribution function to the shape of the superconducting electrodes, the Josephson current was suppressed with a small magnetic field of about 1mT. There were no oscillatory sidelobes in the Josephson current dependence on the magnetic field. We fabricated normal-distribution-function shaped junctions using a Nb/AlO_x/Nb process. The normal-distribution junctions fabricated were cooled down at 4.2K and 0.3K. In the experiments no sidelobes of the Josephson current and Fiske steps could be observed with an external magnetic field of about 1mT. Preliminary experiments showed X-ray detected signals with a magnetic field of 5mT. |
