Abstract
We report the fabrication and characterization of high quality tantalum films as absorbers for STJ radiation detectors. Values of the residual resistance ratio up to 75 and bulk value of the superconducting transition temperature Tc=4.5±0.1 K have been achieved. Devices for detection with lateral aluminum superconducting tunnel junctions have been fabricated on such films. The detector response to X-ray is discussed.
