A a new, multi-purpose differential 3-foil plunger has been commissioned. It can be used together with several gamma-ray spectrometers and charged-particle detectors, due to its compact size. As a commissioning experiment, level lifetimes of the 21+ and the 41+ excited states of 50Cr have been measured, using the Differential Decay Curve (DDC) method for 3-foil plungers. This experiment was conducted at the Cologne FN Tandem Accelerator, using the reaction 24Mg(32S,4p2n)50Cr. Results of this measurement with special respect to the performance of the 3-foil plunger device are presented. This project was supported by the BMBF under the contract number 05P18PKFN9.
