(Color online) (a) Side-view optical micrograph of the composite TES microcalorimeter. (b) A composite TES array. (c) Spectrum of optimally filtered and drift-corrected pulse heights from , with lines at 97 and . The inset graph shows the peak, where the solid line is a least-squares Gaussian fit with . A simple scaling predicts that a similar detector with collection area would have . (d) Thermal model of the composite microcalorimeter.

(Color online) Parametric plot of vs from . Solid lines are fits to , where is the function of and the thermal parameters of the model shown in the figure. is the equilibrium power dissipated in the TES. The single dotted line is the prediction of the thermal model with no and for and the other parameters fixed.
