“…We have devised and tested a new type of cathode which reduces the power dissipation in the cathode region by dividing the gas flow into several channels (multichannel cathodes). 5 We shall see later that this is an excellent way to obtain a shorter IPC, and therefore, to increase efficiency, which makes multichannel cathodes specially interesting when dealing with large cathode diameters or small flow rates. Moreover, a longer lifetime of these cathodes is to be expected, compared to that of the conventional onechannel hollow cathodes.…”

A new type of gas fed hollow cathode (multichannel cathode) has been studied. Such cathodes operate with a lower voltage drop and higher maximum current density than conventional one-channel cathodes and have a longer lifetime as wei!. Moreover, multichannel cathodes allow operation within a wide range of discharge currents and with extremely low gas flow rates. A theoretical analysis clarifies the principles of the operation of this type of cathode. The experimental results are explained and some general rules are presented for the cathode design.
