Abstract

We analyze several pulse-height analysis schemes aimed at realizing maximum precision with TES (transition-edge sensor) microcalorimeter x-ray detectors. Issues of concern are nonstationary noise when the pulse takes the TES element into a higher resistance region, and variability of pulse shape with energy. Furthermore, system noise affects the precision analysis of pulse heights in two different ways: inaccuracy of the pulse height and variation in the triggering position on the pulse. We show that the weighted fitting of an entire pulse shape to obtain pulse height is an efficient way to obtain high resolution. We give a prescription for obtaining the best estimated pulse shape. A comparison is made between results with pulse shapes derived from different energy regions.
