The PENTATRAP project is a new cryogenic Penning trap setup currently under construction at the MPI-K in Heidelberg. It is dedicated to mass measurements of single highly-charged ions. To achieve high precision, a stack of five cylindrical Penning traps will be utilized. Mass measurements will take place in the central precision trap. Additionally, there are two preparation traps, which enable a fast exchange of the ion of interest and the reference ion. On each end of the trap tower a monitor trap will be placed, where permanent storage of single ions and continuous observation of their cyclotron frequency is possible. For detection of the ions the non destructive image current technique will be applied for each trap. Therefore, the trap electrodes are connected to tuned circuits consisting of high-Q inductors followed by very low-noise cryogenic amplifiers or a SQUID.
On this poster the measurement process as well as the individual detection circuits and their present design status will be presented.
