With the HILITE (High-Intensity Laser Ion-Trap Experiment) Penning trap we plan to investigate relativistic tunnel ionization with highly charged ions. High-intensity laser pulses of the order of 1019 W/cm2 from the JETI laser facility will be utilized. One of the resulting phenomena of high-intensity light-matter interaction is tunnel ionization, which is dominant at these parameters. We present related calculations for our setup from recent relativistic tunnel ionization theories. A comparison with results from the non-relativistic ADK theory is also made. The expected yields of ionizations is calculated considering the single-particle ionization rate and the overlap of the pulse with the ion cloud and the results of the theories are compared with each other.
