Description
The \textsc{Alphatrap} experiment \cite{alphatrap} is a double Penning trap setup at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. The cryogenic trap setup allows for high precision spectroscopic measurements on single ions while utilizing the continuous Stern-Gerlach effect for state detection \cite{csge}.
It is connected to a room temperature beamline with access to several different ion sources and thus a wide range of charge states are available for measurements. A cryogenic valve results in a residual pressure of below 10
%\noindent
In this contribution, I will give an overview of our setup and recent measurement campaigns. With our recent determination of the
I will focus on the spectroscopy of single molecular hydrogen ions, in particular the hyperfine spectroscopy of HD
