High Voltage inverter KIT

March 10, 2018

This blog was home to some exciting high voltage related experiments already. While my time for hobbies is becoming increasingly limited, I recently got a HV-1 high voltage inverter KIT and decided to show it here. It’s a one transistor oscillator, with a feedback coil in a compact high voltage transformer. It’s identical to the first high voltage inverter I’ve built, except for the flyback transformer. Even with its tiny…


UT50 NaI Scintillation probe

August 7, 2013

I met some great people today, and I also got a wonderful device for my ongoing experiments as a gift: The UT50 Scintillation probe, manufactured by SC ICPM SA Romania. It features a huge NaI(TL) crystal, with a diameter of 5.5cm and 5.5cm length. The photomultiplier is a British EMI9656KB and the entire device is encapsulated in an aluminum modular cylinder of no more than 24cm total length and 1270g…
