The World's largest Penning trap with an inner diameter of 180 mm with a unique length/radius ratio of l/r0=3.72. The facility allow to perform in-trap and post-trap decay experiments. It has been demonstrated that one can use a single Penning trap system to purify the trapped ion bunch and perform mass measurements. Mass measurement precision of 10-8 has been reached for stable isotopes 23Na, 85,87Rb and 133Cs. Ion motions were manipulated by implementing different excitation schemes. [Display omitted]
