Abstract

Inventia se refera la un sistem de sustinere si izolare electrica a catodului utilizat la instalatiile cu fascicul de electroni în plasma (catod rece), pentru tratamente termice. Pentru sustinerea si izolarea catodului "rece" se utilizeaza izolatoriceramici de mici dimensiuni si mare densitate. Catodul este introdus în incinta vidata, asigurîndu-se conditiile de etansare la vid si izolare electrica fata de carcasa incintei în conditiile Paschen. Sistemul se utilizeaza la sustinerea si izolareaelectrica a catozilor "reci" în instalatiile cu fascicul de electroni în plasma care lucreaza la presiuni de circa 10 exponent -2 mbar pentru tratamente termice, termochimice, depuneri de straturi, crestere de monocristale, sudura, rafinare, topire de materiale greu fuzibile. Principalele avantaje constau în eliminarea degenerarii descarcarii în arc, creînd conditii pentru lucru în impulsuri de mare putere si scurta durata, putîndu-se controla energia fasciculului de electroni.The invention relates to a system for supporting and electrically insulating the cathode used in plasma electrode systems (cold cathode) for thermal treatments. In order to support and isolate the cold cathode, low-density and high density isolating ceramics are used. The cathode is introduced into the vacuum enclosure, ensuring the vacuum sealing conditions and electrical insulation against the enclosure housing under Paschen conditions. The system is used to support and isolate electrodes of "cold" cathodes in plasma electron beam installations that work at pressures of about 10 exponent -2 mbar for thermal treatments, thermochemicals, deposition of layers, monocrystalline growth, welding, refining, melting of fusible materials. The main advantages are the elimination of arc discharge degeneration, creating conditions for working in high power pulses and short duration, controlling the energy of the electron beam.
