Patent DE-19717127-A1 (DE)
Title: Excitation of gas discharge with short voltage pulses
Inventor: NEFF WILLI DR
IPC: H01J37/32
Filed: 1997-04-23
Abstract: The gas discharge is acted on by a first alternating voltage in the range of 500 Hz to 50 kHz, still without triggering the discharge. Individual voltage pulses with considerably shorter rise time are superimposed on the first voltage to trigger the gas discharge. Preferably, the first voltage is very close to the resonance frequency of the oscillation circuit formed of the capacitive untriggered gas discharge and the inductance of a terminal power transmitter. The apparatus for carrying out the method has a switch generator with a first rectifier working at a first frequency, and a transformer (TR1) to generate the first voltage. The apparatus also has a further switch generator to generate the short voltage pulses and to add them to the first voltage.
Patent DE-19719881-A1 (DE)
Title: Ionisation and electron multiplication using gas and liquid mercury
Inventor: ALMUBARAK MEHDI ALI DR
IPC: H02N11/00
Filed: 1997-05-12
Abstract: In an electron multiplication process, the electron or ion enters into an electric field of voltage intensity (E) and is attracted in the direction towards the oppositely charged electrode. The strength of the attraction is output as the result of the charge on the ion or electron and the field energy. This produces an acceleration which in relation to the force of the attraction satisfies the equation E*e equals m*g where m is the mass of the ions or electrons. The acceleration potential exceeds the ionisation potential of mercury and argon atoms. Electrons of these atoms are used and charged mercury and argon ions are generated together with the electrons. The charged ions generated can be further ionised.
