Description
High voltage platform are of widespread use in nuclear physics accelerator in order to provide the initial acceleration of ion. The ion source environment is particular challeging for high voltage holding, since discharge can be energized from source radiation or secondary particle generated by the ion beam.
Moreover spectrometers for charge to mass ratio of exotic nuclei requires a well defined beam energy, which poses challenging requests to high voltage design, rising the question of which electrode design rules are necessary for quiet voltage operation, with typically tolerable energy rms fluctuation in the 10$^-5$ order, including contributions fron all devices in a beamline (spanning a 10 m size). Need for thick plate ground is discussed and compared to existing installation
