Why Are the Russians Still Using Vacuum Tubes In Many Technologies, EMP?
Thanks mike s, So Not Stupid.
EMP's or Electro-Magnetic Pulses could knock out our entire defense system which runs by PC's...EMP's shut down all electronics including PC's!!
These weapons are not directly responsible for the loss of lives, but can disable some of the electronic systems on which industrialized nations are highly dependent.
Devices that are susceptible to EMP damage, from most to least vulnerable:
1. Integrated circuits (ICs), CPUs, silicon chips.
2. Transistors.
3. Vacuum tubes (also known as thermionic valves).
4. Inductors, motors.
Transistor technology is likely to fail and old vacuum equipment survive. However, different types of transistors and ICs show different sensitivity to electromagnetism; bipolar ICs and transistors are much less sensitive than FETs and especially MOSFETs. To protect sensitive electronics, a Faraday cage must be placed around the item. Some makeshift Faraday cages have been suggested, such as aluminium or aluminum foil.
