| This experiment was built to study pure electron plasmas in Malmberg-Penning traps. The picture above (click on the image for a larger and more detailed picture) shows the orange glow of the electron-emitting filament at the axis of the trap (near the center of the picture). The light near the top of the photo is from a vacuum gauge (ionization gauge) used to monitor the pressure of the background gas, which is as low as 10^-10 Torr (1 atm = 760 Torr). |
| Our plasmas are confined at Princeton University where we are studying the effects background neutrals have on the plasma confinement and stability. This may lead to the development of a pressure gauge if the electron-neutral collision cross section is known. Alternatively, if the pressure is known by other means, the cross-section may be deduced. |
