Re: Simulation Data for Ion Interactions with Target Materials from Ion Beam and Plasma Systems

A few updates on the simulation progress and previous posts. After a couple of weeks of playing around with various angular distributions and browsing literature on the subject, I finally found the appropriate general angular distributions for ion angles impinging on grounded walls in plasma reactor...

Re: Simulation Data for Ion Interactions with Target Materials from Ion Beam and Plasma Systems

John, I finally found the results you did in SRIM for Steven Sesselmann. Very cool to see. SRIM is quite an amazingly powerful tool, and even more amazing that it is free. There are many textbooks even dating back to the 70s that refer to the use of SRIM and TRIM for sputtering and implantation simu...

Re: Simulation Data for Ion Interactions with Target Materials from Ion Beam and Plasma Systems

John, Thank you for your reply and input. I will definitely search the forums to check out your simulation results, I don't think I have seen them yet. The reason I am using such low energy ions is that this first initial case is not looking at sputtering and implantation due to operating the fusor,...

Re: Simulation Data for Ion Interactions with Target Materials from Ion Beam and Plasma Systems

UPDATE 04/19/2018 Previously in this post I had written a very long and detailed description of simulations that were run using SRIM 2013/TRIM for looking at the effects of ion energy distribution for implantation depth and sputtering in a 500V DC glow discharge plasma, including various graphs and ...

Simulation Data for Ion Interactions with Target Materials from Ion Beam and Plasma Systems

Over the past three weeks or so I have been working on a variety of simulations to better understand and provide data on a variety of interactions and mechanisms between ions and surfaces interacting with the ions. These simulations range from simple stopping ranges to much more sophisticated modeli...

Re: Stainless steel pipe chamber

Here are a bunch of papers I have found so far on low power permanent magnet cyclotron design and construction: Magnet System for PET Cyclotron Based on Permanent Magnets.PDF Development of a Compact Permanent Magnet Cyclotron for Accelerator Mass Spectrometry.PDF Design of a Compact Permanent Magne...

Re: Stainless steel pipe chamber

Chris, Thanks a ton for the links! I didn't realize miniature permanent magnet cyclotrons have been explored here before! I will post the papers I found for permanent magnet cyclotrons, they might give others some new ideas for different ways of going about constructing them. I think a very small an...

Re: Stainless steel pipe chamber

This cyclotron project has really inspired and revived my interest in these types of devices. Though I will probably not have the chance to pursue one due to a huge backlog of other ion beam systems I am working on, it has given me a lot to think about. Browsing through the literature, it does appea...

Re: Stainless steel pipe chamber

Chris, Sounds like you got a solid plan and a lot to experiment with! 10KW into this system is a pretty huge power draw for a home experimental setup, though it is certainly understandable why you would want this much power! 1.8 Tesla would definitely be a substantial field strength, and you would b...

Re: Stainless steel pipe chamber

Chris, I was going to suggest Poisson Superfish, but it sounds like you have done very thorough research! That is definitely not a common program, and really only people in this field know about it. I've only used it for electrostatics, but it will definitely serve you well for the magnetic simulati...
