Transition edge sensor (TES)-based gamma ray detectors have been developed primarily for use up to energies of {approx}100 keV. However, there are many interesting applications at higher energies. We have started to develop a TES gamma-ray detector to apply to Positron Annihilation Spectroscopy analysis at 511 keV. Our detector is composed of a bulk lead absorber, which is coupled to a thin-film TES using a small amount of epoxy. The response of our first detector showed a very long decay tail of {approx}135 ms. To improve the device response time we have designed a new detector in which the response time is improved by a factor of five.
