Re: How to figure out the specs of old Rigaku scintillation tube probe?

Harald, I would strongly suggest you research more into the fundamentals of beam systems, beam optics, and beam instrumentation to save yourself a lot of frustration and money pursuing methods that will not yield results you are looking for. While you can reverse the polarity of a gun and use it as ...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Chris brings up a very good point. Something like MegunoLink could be used to interface with your high speed acquisition modules and synchronize everything. You wouldn't use the software or arduino by itself for the high speed acquisition part directly. I know that the software can in theory support...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

My control and acquisition system is only for infrastructure currently, not integrating different high-precision timed instruments. For my systems (both the accelerator and propulsion chamber), chances are I will be going the very old-school route and be using an older multi-channel decent-bandwidth...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Harold, Yes, you are correct about MegunoLink and Arduino not being able to do high frequency sampling like a scope. For my system, I am only using it for very slow changing monitoring and interlocking of the infrastructure. So like temperature sensors, flow sensors, and vacuum sensors, as well as p...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

I have also been exploring MegunoLink with an Arduino Mega controller for my system as well. So far I am quite happy with it, and customer support has been great. I'm only about maybe 1/3 done with my code, but it has made creating a user control interface with monitoring and data collection very ea...

Re: Hello from Germany

Awesome! Very cool that you were involved in an official Cubesat project yourself! There is definitely a lot of start-ups popping up all over the place for space propulsion. Problem is, the technology is still absurdly expensive, and chances are many open source and small groups launching small sate...

Re: Hello from Germany

Wolfgang Bauer, Welcome to the forum. Like yourself, one of my main interests is electric propulsion for space applications. I don't believe there are very many others here who are working on propulsion projects, but it is still a great resource for the necessary vacuum related information you will ...

Re: Request for Verified Specifications of Amateur Accelerators

Chris Mullins, Thanks a bunch for the specs on your cyclotron! It is great to see that you have very repeatable methods for determining beam current and energy. I definitely look forward to seeing how your effort progresses, and if you can hit your peak beam energy! I have looked over Tim Koeth's wo...

Re: Request for Verified Specifications of Amateur Accelerators

Ian Krase, Once I have achieved (or at least attempted) first beam, I will begin releasing information and specs on the accelerator. It is nothing new or novel - it is in fact a very old accelerator technology, that, as far as I am aware, has not been built at the amateur level yet (though I could b...

Request for Verified Specifications of Amateur Accelerators

For those of you who have been following my progress, builds, and posts (both on these forums and in other hobbyist communities), you will know that I am currently in the process of designing and building an industrial-grade/research-class accelerator, which I hope will open up a new level of accele...
