After waiting for the right LT1534-1 ICs to arrive, today I finally completed the HV supply.

I've powered them up and tested them. The gods were kind because everything worked perfectly from the first try. 

The 2 boards, assembled and tested.

Thermal image. Hottest component under load is the Controller IC, clocking in at 40 Degrees Celsius.

Powering the detector with the brand new supply.

The 2 finished supplies.

Big Orandge Drop capacitors. I tried 2 different configurations of the output Pi RC filter. Both seemed to perform equally good.

Output noise measured in a 100MHz bandwith is around 1.5-2 mV. Didn't take a photo of the measurement setup because i was juggling 3 probes, decoupling caps and knobs.
