All pumping equipment is built by principle of pumping "vacuum in a vacuum". Vacuum in the system of pumping of a good is about 10-7-10-9 mm of mercury as a rule. The penning type pumps are used as high-vacuum facilities of pumping. Temperature of degassing is gain till 600 °—. Process of pumping is on automated control by microprocessor.
Thermal equipment (options for soldering of high-frequency currents, hydrogen stoves, vacuum stoves).
Equipment for the welding:
The enterprise possesses technology of fabrication of soldering nodes from different material, as well as from ceramics corresponding to the high demands of vacuum tightness and mechanical tougness.
used solders: on the base of copper, gold, silver
equipment: general heating (bell-type and travelling ovens)
local heating (setting of solderings by the currents of high frequency)
ambience of the soldering: hydrogen, vacuum, mixture of hydrogen and nitrogen
JSC "Pluton" possesses technology of the welding of thin-walled, homogeneous and heterogeneous material.
Applicable types of the welding:
Connected material: stainless steel, copper, copper+iron, kovar+steel and others, all the manner of combinations of ferrous, and non-ferrous metals of the 0.08-1.05 mm thickness.
Welded joints are hermetized, vacuum-tighted, mechanical toughness corresponds to main material.
Making of cathodes.
For the different types of electro-vacuum devices of micro-wave range of wave-length produced on JSC “Pluton” in the department of the cathode systems the following basic types of effective cathodes are developed and made:
The output of suitable wares at the use of similar cathodes is 80÷90% at the coefficient of the use of scarce and expensive material ~ 60÷70%.
For separate devices to which the promoted requirements are produced to the output parameters, the knots of cathodes before rising in wares are exposed to the different types of tests, including cyclic tests.
Nowadays with the purpose of reliability increase, stability and producing of parameters of emission during all term of service of devices, in JSC “Pluton” the researches on creation for the powerful magnetrons of the high efficiency combined and component cathodes’ knots are conducted.
The researches on modification of emitting surface of dispenser cathodes and inner-vacuum elements of wares by the means of powerful streams of impulse plasma can present considerable scientific and practical interest for the developers of electrovacuum devices.
