Light through a wall - The ALPS experiment is a seemingly proposal to make “light shine through a wall”. To achieve this, a laser beam is directed through a powerful magnetic field generated by decommissioned dipole magnets from the HERA ring accelerator. In the event that WISPs (weakly interacting sub-eV particles) do actually exist, some of the photons (particles of light) in the laser beam should disappear and change into lightweight particles (Axion). Installed in the middle between the magnets is a wall that stops the laser beam. The theory is that any WISPs produced would be able to pass through the wall – since they react so rarely with other particles, solid matter is no obstacle for them.

To achieve the necessary measurement results, TEWS TAMC532 MicroTCA ADCs are used here in a completely different way, as they are used in High Energy experiments or accelerators like FLASH or XFEL. Instead of getting a 10 Hz trigger, they have to be used in a way to measure constantly with 16kHz triggers over months without any interruption and a highly stable timing source.

In this talk it will be shown how the technical implementation has been done inside the DOOCS control system at DESY.
