Abstract:
An apparatus for rotating at least one workpiece, comprising:a platform; at least one electrically conductive, rotatably driven sample rod having an upper end and a lower end; a rotary drive engaging with the upper end of the at least one rod to rotate the at least one rod; a pivot bearing; at least one high-voltage lead-in line contacting the lower end of the at least one rod for delivering a high voltage to the lower end of the at least one rod via the pivot bearing; and a first insulating arrangement insulating the at least one rod from the rotary drive so as to withstand the high voltage; a second insulating arrangement insulating the pivot bearing from the platform so as to withstand the high voltage; and an attachment element configured to hold the at least one workpiece arranged on the sample rod between the first insulating arrangement and the second insulating arrangement.
