Re: Impulse Executable for Windows

John, Your approach to using Audacity to set the gain is good 👍, the sound card has a dynamic range of around +- 1.2 Volts so if your pulses are clipping at the top, then your gain is too high. Some huge pulses from cosmic rays and other noise will always hit the ceiling but 99% should be within the...

Spectrum sharing...

Hi All, In the recent edition of IMPULSE I included a new feature where users can share spectra with other users, but so far the participation has been weak, a few people have tested it. I thought it would be a neat way to compare detectors and a place for new users to compare their own results with...

Re: Impulse Executable for Windows

In preparation for the release of the new GS-MAX I have been doing further upgrades to Impulse. Not too many changes for those using the Gammaspectacular, but if you are already on the GS-MAX-14 or Atom-Nano devices then the latest version will offer more control.

Ken,

Sorry, due to a lack of interest all this stuff went to e-waste recycling years ago 😥

Re: Potassium Chloride Salt - Radioactive Salt

It seems unlikely, although KCl usually doesn't have much activity it usually stands out against the background, but what size scintillator are you using?

Small crystals are almost blind to gamma rays with energy over 1 MeV.

Re: Hello from Lewiston South Australia

Hello ken,

Welcome to the forum. Semi rural South Australia sounds nice, although it get's pretty hot over there in summer.

Hope you find some interesting discussions to join in on.

Re: Impulse Executable for Windows

As more people are trying Impulse and giving me feedback, I have been fixing bugs and making small improvements.

The latest versions for both Mac and PC are up to date as of yesterday.

Re: LND 50316 proportional detector

Ara,

As Svilen said, please give yourself an introduction and add a real name to your signature.

Ion chambers typically don't output a pulse, they measure tiny differences in potential due to a continuous flow of electrons caused by the bias.

Re: LND 50316 proportional detector

Ara,

This looks like a high pressure ion chamber...

Impulse Executable for Windows

Victory at last after a long battle with Windows.... Anyone game to test this app and provide some feedback? I have been developing this app on a Mac, so it has been failrly easy to release regular updates in .app format, but Windows threw a bunch off errors every time and I had to investigate each ...
