Ionization Characteristics of Cold Cathode Relay Tubes with Radioisotopes

Design and Simulation of Hot Cathode Ionization Vacuum Gauge with no X-Ray Limitations

In this paper, the MEMS type ionization gauge with no X-Ray limitations has been presented. Having the dimensions of 2.4 mm× 0.8mm × 1.4 mm, the designed gauge is 9000 times smaller than the conventional type and can operate in HV and UHV pressures up to 5×10-9 torr. Operating at the temperature of 750°C, the cathode of proposed gauge is implemented using nickel and works in a way in...

Characteristics of a cold cathode electron source combined with secondary electron emission in a FED

In electron beam devices, the voltage applied to the cathode (w.r.t. grid voltage) provides the initial energy for the electrons. Based on the type of electron emission, the electron sources are (mainly) classified into thermionic cathodes and cold cathodes. The power consumption of a cold cathode is smaller than that of a thermionic cathode. The delay time of the electron emission from a cold ...

Development of an Ion Emitter with Hollow Cold Cathode

Ion physics forms the basis for numerous modern technologies and research directions such as microelectronics, material research, analytics or high-energy physics. The reason for the broad range applications of ion physics lies in the ions characteristics: -The ions possess a mass, which makes a direct energy transfer possible to the solid atoms (flexible energy transmission); -The velocity of ...

Test of Duoplasmatron with Cold Cathode for Cw Operation

Pulse duoplasmatron with cold cathode used at preinjectors of ITEP proton linacs has been tested for generation of dc proton beam. The operation of duoplasmatron was studied experimentally with low currents of discharge. The test bench experiments allowed to modify construction of pulsed ion source for stable dc operation with high life time. The ion source generated dc beam of protons with cur...
