AlphaHound Teardown and Mylar Replacement

[@project-326]

Very interesting to see the internals, I can't wait to do my own teardown...

[@8u88letea]

randomly came across this video. First time I've ever seen a dosimeter that gives a reading visually, that's so cool. very sci fi like

[@RadioactiveDrew]

Interesting way to remove Hex screws.

Results may vary ;)

I am so pleased with my Alphahound AB+. This is such a sturdy built device and made really well. Im about to conduct some studies of soil and put it through its paces. Thank you for putting this video out to show us step by step how to change the mylar. Really satisfied with it so far.

Can't wait till I can purchase mine!

[@atece394]

Awesome! Can't wait until I have mine…

Greetings to the author of the channel! I'd like to know something about the device, if you don't mind. I really liked the device. Who produces it (country of origin)? Is this device a government measuring instrument? And can I order one like this to Russia?

What was that a this old tony reference in the start?

[@JOHN0577ANDFRIENDS]

Are you planning on adding physical controls like a small dial or something reminiscent of an mp3 wheel?

[@RadViewNick]

Yes! We will have a left middle right button setup in January. It will include a gamma mod for the full alpha beta gamma detection, each with separation.

​@@RadViewNick Will the new version be bigger? Price difference from Ah+?

[@RadViewNick]

@ The upgrade/mod kit will be the same size and form factor. It is all internal. You can add the upgrade board to any AlphaHound. Prices are not final yet but the standalone upgrade will be around $190 and if you order it at the same time as your AlphaHound it will be around $150 for a total of $540 for an AB+G. It will still hold all of the alpha beta separation properties as the AB+.

Very nice, is there an option with clicking sound?

[@RadViewNick]

@@plutoniumiscool Sound will be added along with gamma detection/buttons with an upgrade mod available in the coming year. The AlphaHound as it is was built to be a discrete device for antique hunting, so we chose visuals rather than audio!

The scintillation view is, “fake” right? I get that the counts are real, I just mean that the photodetector isn’t an XY array and that the dots are aligned to the locations of light emissions in the scintillation Crystal right? Man I just bought a Radiacode 103G, have a 102, 701A, and a GMC I forget the model of. Might have to grab one of these. Would be cool if you could PVD the SS housing or to Ti that’s been heat treated for the cool rainbow effect.

@@JamesReedy We have baked the stainless steel chassis! I’ve even hit one with a blow touch. The sparkles are not positions sensitive but that’s a project i’ve been prototyping that’s way too expensive lol. The sparkles are very aligned with the timing of each hit because we refresh the screen at 30fps. A position sensitive model could be done in the future but it might be a bit too neiche for the cost.

@@RadViewNicknice wasn’t sure what the photodetector really is all the way down to the design level. I know high level it’s a photodetector that looks at a scintillation crystal that produces flashes of light whose intensity are proportional to the energy of the alpha/beta particles or gamma/x-rays. But past that I don’t know if it’s a single output just sampled really fast by an ADC or if it’s an array XY that’s scanned like a camera sensor. To do the spectroscopy I would imagine you can’t really afford to have events blend together which implies you’d need to scan pretty fast to get the individual events to get their energies and plot them as a probability distribution type graph of energy and frequency. Then again I see scintillators hooked to sound cards and those generally max out at 192kHz so Nyquist of 96kHz which seems too slow to count discrete events at really high count rates. I’m an engineer FWIW but I’m not building Geiger counters or spectrometers I’m just curious a bit more about how they work.
