Query: Characterization, 1064 nm photon signals and background events of a
  tungsten TES detector for the ALPS experiment   The high efficiency, low-background, and single-photon detection with
transition-edge sensors (TES) is making this type of detector attractive in
widely different types of application. In this paper, we present first
characterizations of a TES to be used in the Any Light Particle Search (ALPS)
experiment searching for new fundamental ultra-light particles. Firstly, we
describe the setup and the main components of the ALPS TES detector (TES,
millikelvin-cryostat and SQUID read-out) and their performances. Secondly, we
explain a dedicated analysis method for single-photon spectroscopy and
rejection of non-photon background. Finally, we report on results from
extensive background measurements. Considering an event-selection, optimized
for a wavelength of $1064~{\rm nm}$, we achieved a background suppression of
$\sim 10^{-3}$ with a $\sim 50~\%$ efficiency for photons passing the
selection. The resulting overall efficiency was $23~\%$ with a dark count rate
of $8.6 \cdot 10^{-3}~{\rm s}^{-1}$. We observed that pile-up events of thermal
photons are the main background component.
