(a) Schematics of the cantilevered absorbers. The square gray outline marks the edge of the absorbers, which are supported only at the contact areas shown shaded in black. (b) Photograph of TES array with electroplated Au absorbers.
(a) Optimally filtered pulse height spectrum with lines. The solid line shows the least-squares best fit, and the dotted line shows the natural line shape, from Hölzer et al. (Ref. 4) with correction and extension (Ref. 5). (b) Distribution of and (FWHM) of 13 devices. The bin size of is comparable to typical statistical errors associated with the individual spectral fits.
(a) Circles, squares, and diamonds show , , and the ratio of the excess noise to the Johnson noise, respectively, vs bias point. The dotted line, to be read using the excess-noise axis, shows using the determined at each bias point. [(b) and (c)] Circles, squares, and diamonds show , , and raw pulse height, respectively, vs bias point. Filled markers are actual data and open markers are simulations.
