The Orsay Universal Plunger System

The plunger device was commissioned with an experiment performed at the IPN Orsay Tandem accelerator laboratory using the Orgam germanium detector array. Excited states in 76Kr were populated using the reaction 45Sc(35Cl,2p2n)76Kr. The lifetime τ of the 41+ state was determined to 4.3(6) ps, in accordance with previous measurement, confirming the functionality of the new plunger device. The commissioning experiment showed in particular that the electronic feed back system works as foreseen.
