Description
MAGIX is a versatile fixed-target experiment and will be built on the new accelerator MESA (Mainz Energy-Recovering Superconducting Accelerator) in Mainz. The accelerator will deliver polarized electron beams with currents up to $1\,\mathrm{mA}$ and energy up to $105\,\mathrm{MeV}$. Using its internal gas-target, MAGIX will reach a luminosity of $O\left(10^{35}\,\mathrm{cm}^{-2}\mathrm{s}^{-1}\right)$. This allows to study processes with very low cross section at small momentum transfer in a rich physical program.
The poster presents the planned measurements of the inverse kinematic of the nucleosynthesis process $^{12}C\left(\alpha,\gamma\right)\!~^{16}O$ to determine its S-factor. In the experiment we will scatter electrons on oxygen atoms and we will detect the scattered electrons in coincidence with the produced α-particles. With this measurement we will determine the cross section as a function of the outgoing center of mass energy of the carbon-α-system, to calculate the S-factor. We will hereby present the results of the first simulations which can be used to understand the parameter range that MAGIX will be able to explore.
