A nonconvectional hollow cathode discharge (HCD) modification grounded on a conical bottom (CB) cylindrical cathode is reported. this CBHCD enhances the main HCD property, i.e., the sputtering of the cathode surface/probe inserted. Comparative polarisation measurements with a conventional flat bottom HCD show a stronger narrowing of the Hanle signal width for the sputtered Cu atoms in CBHCD.This their density is higher in CBHCD. This result is specified by the redial optogalvanic profile. It contains two peaks of the mentioned density, i.e., near the cylindrical cathode surface and over the cone peak. Some preliminary examinations of CBHCD as an ion source in three arrangements are performed and discussed.
