Re: Simple Thorium Linearity Check with Excel

Thank you for the excellent graph. You have now inspired me to go get some Thorium dioxide today. 100g vial. :)

Re: Simple Arduino Pulse Rate Counter

If using a teensy 3.6 or 4.0, one can use the FreqCount and FreqMeasure together for 0.01CPS - ~80MCPS (Standard without overclocking). Just use the libraries and add the appropriate math and signal acquisition times for both lib.h s to work in. Write the counts to a display with an averaging while ...

Re: My lead house for spectrometer

Very nice shield. This is in fact the same style of construction that I was proposing for my build. Lead flashing is absolutely perfect and more pure than the lead shot which is up to 10% Antimony in some cases.
Next project phase for my spectroscopy setup.

Re: GS-USB-PRO (V3.2) From Serial #1406 and above.

Nice changes. Just thinking, for those people using faster scintillation mediums a TLV320ADC5140 capable of 768Khz sampling might be something to look into? CLK input would be ~36.8Mhz
I like your product and small changes. It keeps evolving :)

Re: Pushing an Arduino to the limit.

If you need a more "boosted" arduino, take a look at the new models, they come with ARM Processor which is much more powerfull (48Mhz instead of 16) Yes, why I recommended the Teensy 3.6 or Teensy 4.... These are Cortex ARM M4 (Teesny 3.6) 250Mhz and Cortex ARM M7.. capable of 1Ghz each are capable...

Re: Fun with LaBr3

Love to do a price comparison with CeBr3 to LaBr3. I am really interested to making a small homerolled scintillation detector with either medium.

Already have a very small CsI/Na scintillation detector that resolves low energy quite well.

Going back to S.Korea for a family visit

I am on my way back to Seoul to go visit family due to an emergency. Will be there for 3 weeks. While I am there I plan on visiting yongsan-gu, was home to an electronics market.. not sure about now, as well as the few new maker-spaces (including the FabLab) in Jongro-5 ga. Should be interesting. I ...

Re: HPGe detector back to life after long sleep

Lovely post! I wish I had one of those too.. Very exact! Curious, what are you using to capture the spectrum in terms of A/D?

Very nice reports Massimo, both of them! Thanks for taking the time to share this experience and the pictures too.
