Abstract
We demonstrate high bandwidth and low noise readout of a superconductor-insulator-normal metal-insulator-superconductor hot-electron bolometer element. We measure a noise equivalent temperature of better than .06 'K/Hz' and infer an electrical noise equivalent power of 7 x 10'17W/Hz' for a normal metal volume of 4.5'm 3 at an operating temperature of 270 mK. Using a pulsed bias technique we measure a thermal time constant of 1.2 's at 270mK. The microwave readout method we employ is compatible with large format arrays of 10-3-10-5 pixels required for future far-infrared space based observatoriesCitation
