Collection of information about russian SNM tubes

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

In response to your question....Are not my quotes those from Steven Sesselmann's on this same page?....In response... Yes, they are his exact words and they are absolutely unnecessary. We have already read those words of his above and need not be reminded of them. We are smart readers and need not be reminded of the exact words in any preceding posts. Block quotes are any verbiage in your current post that is in shaded gray "block" which quotes from another post within any given entire thread. We do not like block quotes in gray in responses. Your responses in your posts should be all your own words.

The above request is commonly noted to new folks here. Avoid block quotes from previous posts in a thread.

To my knowledge there is no restrictions on posting images of any sort on new people. To the contrary it is highly recommended. A picture is worth a thousand words. Your table of official, published efficiencies was most welcomed.

Note: Block quotes are OK if you are referring to some quote made way back in a thread of some months or years ago. Do not use them in response to a recent running thread

Nice graphs but any chance we can get some translation into English on the key points (graph parameters.) Maybe a bit on the context of the articles - I see it is a voltage vs. some type of response for each detector type.

The RS-P4 and P7 references in the graphs and table are comparison to the famous industry standard Reuter and Stokes P4 (4ATM 3He) and P7 (7ATM 3He) proportional detector tubes to the Russian tubes. I have since 2004 only used the RS-P4, 21-inch long tube in my neutron detection system.

@Michael

Can we get the entire document? I would like to translate.

Thanks

yea, sure - you can download it from The International Atomic Energy Agency website.
sorry guys - don't have much free time now to translate this on my own.
