A main feature of the high-precision mass spectrometer PENTATRAP is an access to highly charged long-lived and stable ions. Well proven sources for highly charged ions are electron beam ion traps (EBITs). PENTATRAP has access to two EBITs for ion production: a small commercial room temperature Dresden-EBIT3 with an additional Wien filter and the Heidelberg-EBIT. The Dresden-EBIT3 is limited to the production of helium- and neon-like ions for medium- and high-Z elements, respectively. Therefore, this ion source will be used for the commissioning of PENTATRAP and for the investigation of its performance. Moreover, it can be used to produce ions for measurements in the field of neutrino physics. For physics applications, which require extremely high charge states of long-lived and stable nuclides, e.g., bare or hydrogen-like lead or uranium, PENTATRAP will obtain ions from the Heidelberg-EBIT. The talk will focus on the Dresden-EBIT3 and first measurements will be presented.
