Query: Eliminating the non-Gaussian spectral response of X-ray absorbers for
  transition-edge sensors   Transition-edge sensors (TES) as microcalorimeters for high-energy-resolution
X-ray spectroscopy are often fabricated with an absorber made of materials with
high Z (for X-ray stopping power) and low heat capacity (for high resolving
power). Bismuth represents one of the most compelling options. TESs with
evaporated bismuth absorbers have shown spectra with undesirable and
unexplained low-energy tails. We have developed TESs with electroplated bismuth
absorbers over a gold layer that are not afflicted by this problem and that
retain the other positive aspects of this material. To better understand these
phenomena, we have studied a series of TESs with gold, gold/evaporated bismuth,
and gold/electroplated bismuth absorbers, fabricated on the same die with
identical thermal coupling. We show that bismuth morphology is linked to the
spectral response of X-ray TES microcalorimeters.
