Therefore, it is planned to measure the g-factor of lithium(Ca) and hydrogenlike (Ca) calcium in a triple Penning trap setup. In the last year substantial progress was achieved: after major technical developments including new cryogenic lownoise amplifiers, first frequency measurements on single ions have been performed.
