    Many thanks for the ion chamber building instructions. I built the ion chamber and used it during a lecture about radon with experiments at the events “Highlights of Physics 2022 in Regensburg, Bavaria”. If you like you can watch my lecture on youtube:

    https://www.youtube.com/watch?v=YEe69a3kaN0

    I am proofing that radon emanates from Uranium minerals by sucking a few milliliters of air from a jar containing uranium minerals and injecting it into the ion chamber. This yields plenty of impulses that are registered with Theremino Geiger.

    I added a link to the building instructions at the end of my presentation so that anyone interested could build it as well.

    I am in concern however that building it according to the building instructions will not succeed. The high voltege converter did not oscillate before i changed C1 33pF to 3,3nF and R2 100k to 10k. This components connect collector of T2 to base of T1. The current through the orginal components is too low to switch T1 off.

    Could anyone confirm that there is a mistake in the schematics ?

    Best regards from Regensburg

      Dear Juergen,
      I designed that scheme and tried it for a long time. Also many copies have already been built and all have always worked well with the schematic components i.e. C1 = 100pF and R2 = 100K

      If it doesn’t work well it is probably due to one of the following causes:
      – T1 transistor which is not a BC846B (or similar with Beta of at least 300)
      – D1 which is not a 1N4148 but perhaps a 4001?
      – Long wire mounting (maybe you haven’t mounted it with SMD components on the PCB recommended by us?
      – Diodes from DZ1 to DZ5 which are not MMSZ5270 or similar but with very low loss and low capacitance.
      – D3, D4 and D5 different from RS1KL and therefore with too much parallel capacity
      – L1 with too much series resistance or with too much capacitance in parallel.
      – Supply voltage too low or 3.3 volt regulator defective
      – Some defective components.

      Furthermore, even in the SPICE simulations the circuit works perfectly with the values of 100pF and 100K

      Best regards
      Livio

    Dear Livio,

    thanks for your suggestions. I checked everything. The voltage convertor was built on a printed SMD PCB of your layout. It is version 5 with a single 10V Z-Diode and voltage divider. I used a BC 807 for T1 which has the same current amplification of 200 as the BC 846B. The rectifiers are also RS1KL . The only difference is the coil. I could not obtain the same coil. Its resistance is probably a bit high at 15 Ohms. The coil seems to be critical in that circuit. Maybe the ferrite characteristics and coil capacitance matter even when the inductance is correct.

    Overall I have to say that the PCB is hard to solder because it is smaller than necessary. Some parts are also hard to obtain. They sometimes are a bit “exotic”. One has to order from multiple different distributors. For example the FET in the pulse amplifier is no longer available. I simply used an old BF245 with leads that I soldered directly to the amplifier board.

    The Ion chamber is working satisfying now. I want to put it online on opensensemap,org if air humdity does not spoil the operation. I already have a geiger counter online and gamma dose rate rises during each rainfall because radon decay products are washed from the air.

    Best regards
    Juergen
