A directly heated thermionic high power electron beam source was constructed. The circular cross-section tungsten line cathode of length 140mm with diameter 0.9mm was used. Different gun design parameters were investigated and their results are discussed in detail. A uniform external magnetic field of 50G was employed for focusing of electron beam...
A simple, high performance indirectly heated axial electron gun has been designed and fabricated. A 0.9-mm-thick and 15-mm-wide tantalum strip was used as a cathode with an emission length of 42 mm. An emission current of 600 mA was achieved at an input heater power of only 116 W. The gun is useful for laboratory experiments as well as welding, eva...
A 140-mm cathode length, Electron Beam Line Source with
a high degree of focusing of the beam is constructed. The design
principles and basic characteristic considerations tor electron beam
line source consists of parallel plate electrode geometric array as
well as a beanTpower of 35kW are worked out. The dimensions of
the beam at the work site are...
