Re: LCD Vacuum Sensor

Is that the Art of Electronics peeking in the corner of the photograph? Great project too, a really convenient way to measure vacuum! By the way, have you considered optical isolation or, more simply, just using a usb isolator if you ever connect this to a PC? I feel it would be an easy way to prote...

Re: Progress on my first fusor project

A basic vacuum system and gas management system can also be used to make gaseous radiation detectors. With a pump that could reach about 10 microns you should be able to avoid the worse effects of electron attachment created by oxygen residue. Backfill this with a P10 mixture (commonly available) th...

Re: Selected Topics in Nuclear Electronics

I feel that the concepts I have to physically get working always stucks with me (while the things that I'm supposed to memorize at class don't really!). It really was a different a time. I think now repairing the various modules like you did back in the 70s would be unthinkable in most cases, due to...

Selected Topics in Nuclear Electronics

Similarly to my previous post, this is a small book that describes the theory of pre amps, SCAs, MCAs, etc... in great detail (it was supposed to be used in the training of technicians working with nuclear instrumentation) created by the IAEA. While it contains some practical details, in is much mor...

Nuclear Electronics Lab Manual

Hi: I paste the link to a lab training manual created by the IAEA that covers everything related to nuclear electronics. I tried to upload it as a file but it said it was too big. I myself have printed this great document as a reference, and I recommend you at least dowload it to avoid losing it due...

Re: Neutron Detection Methods and Instruments

Richard: I got lucky and found the three volumes of Fast Neutron Physics for 20 dollars in great condition! I'm currently digesting all the info. The chapters on long counters and activation are specially great. Joe: Thanks for posting the article! I'm going to print it and bind it, as it is a very ...

Re: Image and file restoration

Jon: I just want to let you know how grateful I am for your huge effort. Due to life getting in the way, I've not been able to post anything interesting of my own making, but I've read a lot on the old threads, and often came across Richard's missing schematics and images. This is just another reaso...

Re: FAQ - Roll your own preamp (Richard Hester design)

Richard: I distinctly remember the "Pathetically Simple Charge Sensitive Amplifier". The simplest CSA I've ever seen! I printed it a couple years back but after an hour of searching I'm afraid It is lost to the sand of times... Searching for it in Google, I found the diagram in Fred's fusor Page ( h...

Re: A boosted GM tube - Report

Richard:

I'm interested if you still had this file. I came from here viewtopic.php?f=13&t=5647&p=37875&hilit ... bes#p37875 and it seems like an interesting experiment.
