We are developing bulk lead absorber coupled transition edge sensor gamma-ray detectors that can be applied to positron annihilation spectroscopy at 511 keV. We observe a double exponential decay in the signal response curves of our detectors. Here, we characterize this signal response using three gamma-ray detectors with different thermal conductance values.
