Re: Radon - a discussion

<t>Home radon levels can easily vary by an order of magnitude or two, with <br/> changes in the weather, presumably due to atmospheric pressure "bottling <br/> up" radon in basement areas or letting it escape outside.<br/> <br/> I've run my air sampler with my GM-45 pancake detector for weeks at a <...

Any info on the Canberra Acquisition Bus ?

<r>Yes, I'm back to playing with my 8076 NIM again. Thanks to some docs <br/> from someone, I'm a lot closer to getting it to work. I had previously <br/> figured out how to control most of the settings, now I have that done, and <br/> am able to get conversion data back from the unit. I'm curious i...

Re: Radon detector for under $100.00

Could you elaborate on how the ion chamber is handled specially? I'm
curious.

Re: Radon detector for under $100.00

Richard,

Have you peeked inside this unit? Is it just an ionization chamber? Anything
unique about it?

Re: Mac OS X software

My Rad software does this through the serial port.

Re: Canberra 2000 NIM Bin Power Supply Question

<t>It's a 610R, the rack mount version. My understanding is that you can't feed <br/> more than 100V into the 610 in voltage mode. So I am using the resistor in <br/> series, as a crude voltage to current converter, then using the 610 in current <br/> mode. <br/> <br/> My plan was to use a 7805 if t...

Re: Canberra 2000 NIM Bin Power Supply Question

<r>Thanks Richard, I had completely forgotten about the pre-TTL logic! I was <br/> considering a switcher, but I have concerns over EMI generated by them. <br/> Perhaps with adequate shielding... I'm using an external 5V bench supply for <br/> the 8076 ADC NIM now, I'll have to measure the required ...

Canberra 2000 NIM Bin Power Supply Question

<t>I'm finally back to working on getting my Canberra 8076 ADC card interfaced <br/> to the computer, and have one question regarding the Canberra 2000 NIM <br/> bin. It has functional +/-12 and +/-24V supplies, but appears to only be wired <br/> for 6V, without having a 6V supply. From some poking ...
