Experimental investigations employing highly charged ions (HCI) typically require very strict vacuum quality. In Penning trap mass spectrometry (PTMS), HCI can significantly improve the precision and resolution of mass measurements, but they are also subject to charge-exchange reactions with neutral gas particles, which may hamper the quality of the measurement. In this study, we employed a simple method to determine that the maximum pressure levels required for an undisturbed PTMS measurement of HCI is on the order of 10-11 mbar. We also evaluate the residual gas pressure in the Penning trap mass spectrometer at TITAN facility by measuring the rate of charge-exchange reactions with HCI, revealing that the trap's vacuum must be improved in about two orders of magnitude to reach the desired level.
