Posted to diyPhysics.com: Testing Electronic Goldmine’s “Giant Super Sensitive Geiger Muller Tube MC6″

I purchased two “Giant Super Sensitive MC6″ GM tubes from Electronic Goldmine (Item Number : G18717, Unit Price: $89.95).  These are Russian-made new-old-stock model MC6.  They are 10.25″ long x 0.9″ diameter.  I compared the sensitivity of these tubes to the other GM tubes that I use with my CDV700 Pro Geiger Counter.  I posted

New Radiation-Detection-Related Posts at www.diyPhysics.com

I just published three scintillation-probe related posts at www.diyPhysics.com. First is on the construction of a very simple low-pass filter to interface commercial PMT amplifiers/scintillation processors to the PRA (“Pulse Recorder and Analyser”) software MCA:

Home-Made Radiac Turns Surplus Military Scintillation Probes into Sensitive, General-Purpose Gamma Radiation Counter

Military-surplus scintillation probes meant for the detection of plutonium contamination are widely available in the surplus market.  The DT590A/PDR-56F “Plutonium-239 Contamination X-Ray Probe” was used with the PDR-56 Radiac Set (radiation detection and measurement instrument), that has been obsoleted by the US Air Force. The probe is designed specifically for detecting the 14 to 21

d.i.y. Handheld Multichannel Analyzer (MCA) based on 16F877 PIC Microcontroller and LCD

Some time ago I was developing a medical instrument which required histogramming, which got me in the mood to retake my own PIC MCA project(http://home.comcast.net/~prutchi/index_files/scint.htm ).   I used the variable RAM in the microcontroller (16F877), so I limited the number of channels to 95 and let the histogram run until some channel reaches 240 counts

We Received The First Copies of Our d.i.y. Quantum Physics Book!

Today we received the first two copies of our new book! It is a do-it-yourself book on Experimental Quantum Physics, and was published by John Wiley & Sons. From the back cover: “Build an intuitive understanding of the principles behind quantum mechanics through practical construction and replication of original experiments. With easy-to-acquire, low-cost materials and

Pictorial Instructions for Modifying ENI CD V700 into David Prutchi’s CDV700 Pro Geiger Counter

We modified a surplus Civil Defense V-700 radiation survey meter made by Electro Neutronics Inc. (Model 6-b) into a very capable radiation counter capable of working with both Geiger-Müller and PMT scintillation probes. We modified the front panel to accommodate the new switches, connectors, and panel light. In addition, we placed a Veeder-Root count totalizer
