      abstract     = {The Any Light Particle Search II (ALPS II) is a
                      Light-Shining-through-a-Wall experiment operating at DESY,
                      Hamburg. Its goal is to probe the existence of axions and
                      axion-like particles (ALPs), possible candidates for dark
                      matter. In the ALPS II region of interest, a rate of photons
                      reconverting from axions/ALPs on the order of $10^{-5}$ cps
                      is predicted by some astrophysical hints. A first science
                      run at lower sensitivity based on a heterodyne detection
                      method was successfully started in May 2023. The design
                      sensitivity is expected to be reached in 2024. A
                      complementary science run is foreseen with a single photon
                      detection scheme. This requires a sensor capable of
                      measuring low-energy photons (1.165 eV) with high efficiency
                      and a low dark count rate. We investigate a tungsten
                      Transition Edge Sensor (TES) system as a photon-counting
                      detector that promises to meet these requirements. This
                      detector exploits the drastic change in resistance caused by
                      the absorption of a single photon when operated in its
                      superconducting transition region at millikelvin
                      temperatures. To achieve the required sensitivity,
                      implementing the TES into the ALPS II experiment needs to be
                      carefully optimized. In this work, we present the progress
                      on measurements for the characterization of our system and
                      data analysis for background reduction.},
