Gamma Spectrometry Forum

Impulse had a simple "Publish" button - when the user clicked publish there was a message modal that asked the user to confirm that this was indeed a calibrated spectrum worth publishing. The spectrum was then converted to a standard number of channels and saved in a standard format. From...

That makes sense. I have been thinking along similar lines, but with a more automated workflow. One possibility would be to have the spectroscopy program automatically contribute spectra to a central cloud database whenever the user runs it, ideally as an opt-in feature. Over time that could build a...

Very interesting, It would be even more interesting to develop an AI that could recognise an uncalibrated spectrum based on its overall shape. Steven This is exactly the direction the experiment is heading. So far, it has been limited to FWHM calculations and individual peak analysis, but with addi...

I wanted to see whether it would be possible to automatically flag specific gamma-ray spectral peaks after calibration using Python-based machine-learning tools. To do this, I built a system with TensorFlow and the Keras API in TensorFlow 2.21.0, which made it easier to develop neural-network models...

For those of you who have Repitaya 125-14 v1 I went ahead, with permission from NuclearPhoenixx / Matthias for making a webapp for the Red pitaya running RP OS v2.07-51. The application works very well and is made to access the FPGA data stream directly. It is lightning quick at creating a spectrum ...

For those using the Red Pitaya 125-14 or 125-10, the original Multichannel Analyzer app (created in 2017 by William Thompson and Pavel Demin) has now been updated to work with the newer Red Pitaya OS 2.07-51. I have rewritten the application in two versions: A web-based app A standalone .exe applica...

good greif that is small ! Nice work :)

I'm asking about the pinout from the tube, not looking for usage in Gamma Spectroscopy as it is, as you say probably not in the best shape. Do you know where I can find a pinout for such a tube?
Looking to do a counting project with it.

I happened across this scintllation detector at a ham radio fleemarket. It was orginally from Ukraine ~ 80's vintage perhaps. has anyone seen one of these before? Is it NaI:Tl ?
Was curious about it.

Thank you for that little bit of code - it's extremely useful for those of us that have analog meters or TTL output. The fast diode 1N4148 coupled with a ~22uF low value electrolytic capacitor and 68KOhm resistor does the trick. I have modified the circuit a little to adapt it to my Bicron Surveyor ...
