Abstract
We present a method for applying optimal filtering to data sets containing energy-dependent pulse shapes. This occurs frequently in transition edge se nsors (TES) when dealing with signal energies that are close to the saturat ion point of the detector. Different filter templates are created which spa n the dynamic range desired for the TES. These filters are then used as tem plates to filter the data, using interpolation to bridge the gap between te mplates. The method has been demonstrated on our tungsten (W) TES. We prese nt the latest results from heat-pulse data on a (125 mu m)(2) TES with reso lutions of 3 eV FWHM at 42 eV and 4 eV FWHM at 1.42 keV with the same senso r demonstrating the wide band operation possible with this technique.
