ELECTRON SPECTROMETER COMMISSIONED


                                                     The  electron  spectrometer  project  was  successfully  commissioned  in
                                                     October, a little later than expected than July when the device faced several
                                                     severe problems in its first tests.  The hard work of the "One iThemba" team
                                                     from  Subatomic  physics,  Instrumentation  and  IT,  and  Accelerator
                                                     departments, all rallied around to fix the device allowing it to take first beam
                                                     at iThemba LABS.  The commissioning aims to study electric monopole (E0)
                                                     transitions in 70Ge, and is the subject of PhD candidate Mr Abraham Avaa of
                                                     Wits / iThemba LABS.
