3V -> 1 kV supply at 1 mW.


Not hard in theory.
Requires modest care in practice - but not hard.

How big can it be? (volume, mass)
How many?
What max cost?
What must it idle at ? (1 mW or ///?)
What battery must it run from?
More ...?
What is it :-) ?


Quick first suggestion - HeNe LASER supply circuits are possiby of use.

If this is a one off then acquiring one may be the easiest path.
There are also numerous DIY ccts for doing this.

You can just use a single stage flyback design.
Some may use a voltage multiplier for various reasons.
At your low power level a flyback should be easy enough.

Here's a 12 V - LASER supply.
Possibly what I've got one of somewhere in my dungeon
T1does all the hard work - the rest is relatively straight forward  in
functionality.
At 1 kV you probably don't need a multiplier.
