First Results of the Any Light Particle Search II (ALPS II) — •Todd Kozlowski for the ALPS collaboration — Deutsches Elektronen-Synchrotron DESY
The Any Light Particle Search II (ALPS II) is an ongoing ’light-shining-through-a-wall’ experiment located at DESY in Hamburg, designed to probe the existence of lightweight bosons through their coupling to photons in a background magnetic field. ALPS II leverages technology developed specifically for this task, including a record-breaking long-baseline optical cavity, an ultra-sensitive detector capable of measuring coherent powers as low as 10−24 W, and a sophisticated optical control system. Since beginning operation in May 2023, ALPS II has conducted several successful measurement campaigns. In this talk, I will discuss the initial results and outline planned upgrades to further enhance the experiment*s sensitivity.
