Re: water cooling with tap water?

<t>We make ICP instruments and all of the ones I have seen so far had the work coil cooled with water and seems common throughout the industry. I was concerned with water conducting the RF when I built my ICP oscillator but did not notice any conduction effects even at 2KW (~4kv Peak). I even tried ...

Re: Understanding Plasma Charge Distribution

<t>I see that if each ring had an equal devision of the supply that, depending on the emission charecteristics of the material, that it has the same configuration as an electron multiplier and therefore the rings closer to the positive will have more current drawn and have a lower propotional voltag...

Re: Langmuir Probe Creation and Design

<t>The clue lies in your last plot.<br/> The voltage on the probe determines what range of energy electrons can have that it will detect. As the voltage on your probe is quite low it can only detect low energy electrons. Fast electrons will whizz past without noticing the small field of your probe. ...

Re: ICP coil first test

Sorry steve, I've been digressing on your thread.
Lyn, While interesting, and obvious that you don't want to share your ideas just yet,
I'm skeptical but content to sit and wait for anything you may later share.
Good luck.
Dustin.

Re: ICP coil first test

<t>The skin effect within the plasma is not obvious but observable in an OES plasma instrument by scanning the plasma. At 27Mhz or even 40Mhz its barely visible at 1.5Kw. 2.4 Ghz it is easily distinguishable but still not very delineated. This seems to be because the plasma has resistance, the curre...

Re: Supply Question

I thought the reason for placing it under vacuum was to cause entrapped bubbles within windings to expand and bubble out. I didn't think it would be required to maintain it under vacuum.

Re: ICP coil first test

<t>I have waged my own wars with skin effect. In this picture is my oscillator partially constructed with silver plated copper straps coupling the tank capacitors to the work coil (gold). The strap is 1.6mm thick and 14mm wide and is water cooled at both ends but the centre of the strap still gets h...
