abstract: An important aspect of precision measurements in a Penning trap is the ability to cool the confined particles to cryogenic temperatures, which reduces the measurement uncertainty.
The ARTEMIS Penning trap, located at the HiTrap facility at GSI, is designed to measure the g−factor of heavy to medium highly charged ions, such as 40Ar13+ and 209Bi82+, using microwave-laser double resonance spectroscopy on a ppb level of accuracy. The foreseen measurement scheme involves spectroscopy of a large number of confined particles in
the form of an ensemble, typically of the order of 105 ions. This thesis presents the development and upgrades of the non-destructive detection system of ARTEMIS, which is also
used for resistive ion cooling through dissipative interaction with the effective resistance of the detection system. A theoretical treatment of resistive cooling of an ion ensemble created in the creation trap of ARTEMIS was performed and test with different ion ensembles.
