Cascade image intensifier tube with independently sealed sections |
摘要 |
A cascade image intensifier is provided with a mica sheet extending across the interior of the tube and sealed to it to separate electrically each stage. A phosphor screen of one stage is formed on one side of the mica sheet and a photocathode of the next stage is formed on the other side. The photocathode may be at a much lower potential than the phosphor screen on the other side of the sheet. This allows electrons to be accelerated in cascade without the use of very high voltages.
