We studied radial compression features of electron plasmas in a Penning trap (an assembly of multi ring electrodes (MRE) housed in a uniform magnetic field) using the rotating wall technique. The magnetic field was 5 T, and the MRE provide a long harmonic potential along the magnetic field axis. The compression features of the plasma were studied by varying the applied rotating electric field frequency, rotating electric field amplitude, compression time, as well as, the magnetic field strength in the Penning trap. The highest density achieved was similar to 5 x 10(10) cm(-3) and the compressed plasma shows slow expansion after the compression, with an expansion rate of 7 x 10(-4) s(-1). (C) 2018 Elsevier B.V.
