2. Krytron - Wikipedia

   en.wikipedia.org/wiki/Krytron

   A sprytron, also known as vacuum krytron or triggered vacuum switch (TVS), is a vacuum, rather than a gas-filled, version. It is designed for use in environments with high levels of ionizing radiation, which might trigger a gas-filled krytron spuriously. It is also more immune to electromagnetic interference than gas-filled tubes.

   en.wikipedia.org/wiki/Vacuum_interrupter

   After the 1970s, vacuum switches began to replace the minimal-oil switches in medium-voltage switchgear. In the early 1980s, SF6 switches and breakers were also gradually replaced by vacuum technology in medium-voltage application. As of 2018, a vacuum circuit breaker had reached 145 kV and the breaking current had reached 200 kA. [4]

   Vacuum systems usually consist of gauges, vapor jet and pumps, vapor traps and valves along with other extensional piping. A vessel that is operating under vacuum system may be any of these types such as processing tank, steam simulator, particle accelerator, or any other type of space that has an enclosed chamber to maintain the system in less than atmospheric gas pressure.

7. List of vacuum-tube computers - Wikipedia

   en.wikipedia.org/wiki/List_of_vacuum-tube_computers

   Vacuum-tube computers, now called first-generation computers, [1] are programmable digital computers using vacuum-tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transistors. Some later computers on the list had both vacuum tubes and transistors.
