The principle and the construction of the emittance conserving chopper at the Munich tandem laboratory will be presented as well as its performance and first operation with beam. The chopper is installed at the high energy side of the MP tandem and consists of two resonant circuits. The first circuit is the actual beam deflector, while the second circuit, which is operated at a higher harmonic frequency of the first one, corrects for both the transversal and longitudinal spreading of the beam caused by the applied fields of the first circuit.
