Summary
| Description |
English: This image shows the plasma created in a vacuum chamber, the ions created are then extracted and sent through a beam line experiment. The setup uses differential pumping: the site where the plasma is created (pictured) is at about 5 orders of magnitude more pressure than the site of collection. This allows for both the pump and the plasma generator to function well (the plasma generator works optimally at higher pressure; to learn more about this, look up 'Paschen's Law'). You can also think about the following: if the pressure is too low (too few ions in the given volume), then the voltage necessary will be much higher. The unused ions are collected with a faraday cup, letting only a small beam of ions through, the equivalent of 1-10 nA. |
