The HILITE Penning trap will provide well-defined ion targets to investigate laser-matter interactions in both the high-intensity and high-energy regime with highly-charged ions. For ion counting we have implemented two distinct single-pass non-destructive charge counters. They measure the time-dependent image charge induced by an ion bunch. From these signals we can directly extract the kinetic energy, the number of ions and the bunch length. We will show a brief overview of the HILITE experiment and present the implemented ion counting technique with detailed characterization results. Here we will focus on the sensitivity of the device and the minimum detectable number of ions. Furthermore, we will outline actions to further increase the signal-to-noise ratio to be even sensitive to less than ten ions per bunch.
