Abstract

The apparatus has a supply device connected to an electrical supply source and having at least a series of seven terminals, the first of which (G2) is connected to earth. The supply device produces at the second terminal (H2) a voltage between 50 and 5000 volts, between the third (E2) and fourth (F2) terminals a voltage between 4 and 20 volts, at the fifth (L2) terminal a voltage between 50 and 3000 volts, at the sixth terminal (M2) a voltage between 500 and 3000 volts, and 4000 to 75000 volts at terminal seven (AT2). There is also a voltage control for the supply current to these terminals, and the voltages specified are with reference to the earth terminal (G2).
