kvizx na piatok

[Jan Waclawek]

Samozrejme som nikdy slovo ignitron nepocul, takze som si to musel
nastudovat.

https://en.wikipedia.org/wiki/Ignitron:

 However, a disadvantage is that the ignition electrode must be positioned
very accurately, just barely touching the surface of the mercury pool,
which means that ignitrons must be installed very accurately within a few
degrees of an upright position. 

Takze nieco co sa v spojitosti s tou lampou pouziva na kontrolu zvislosti?

Druha moznost je, ze ta lampa je nejaka vysokovykonna IR, a hentak sa
ohrieva ta anoda, lebo v datasheete sa vyhrazaju, ze ju treba vyhrievat,
no a ona je na 20kV. Ale to by som cakal, ze henta placacka bude cierna.

wek
