Beschreibung

We present the development and experimental testing of a permanent magnet system to detect electron positron pairs on high intensity laser experiments at Astra Gemini. These experiments where designed to measure fundamental QED phenomena, like the Linear Breit-Wheeler effect as an example for $e^+ e^-$-pair production from quantum vacuum, or strong field effects like the Nonlinear Breit-Wheeler effect, measured on laser $\gamma$-beam collisions or as part of QED cascade processes, triggered by radiation reaction photons.
