Abstract
We report the first demonstration of X-ray detection by using a Superconduc ting Tunnel Junction (STJ) with a microstrip-coil, The STJ was fabricated b ased on Nb/AYAlO(x)/Nb integration process technology using a 2(m)(mu) desi gn rule. Magnetic field was applied into the STJ by the microstrip-coil to suppress the de Josephson current instead of the conventional electromagnet , The output waveform was successfully observed by irradiation of 5.9 keV X -ray under a condition of microstrip-coil current of 20 mA at 0.4 K.
