A study of the motion of single electrons in liquid helium
نویسندگان
چکیده
We have developed an apparatus which can be used to monitor the motion of individual electrons in liquid helium. A sound wave is used to explode an electron bubble for a fraction of a microsecond. While the bubble is expanded, it is illuminated by light from a flash lamp. We describe the details of the experiment and show the results we obtained. The phononroton in liquid helium drags the electron bubbles across the experiment cell. In some cases, an electron is seen to follow a snakelike path. Our tentative explanation is that the electron is sliding along a quantized vortex line.

متن کاملEvaluation of the Effects of Different Filters and Helium Bag on the Reduction of Electron Contamination in Photon Beam of Neptun Linac
Introduction: Skin sparing is one of the most desirable characteristics of high energy photon beams. However, the photons emerging from the target of linacs are contaminated by secondary electrons as a result of their interactions with air, collimators, flattening filter and any other objects in their path. This phenomenon tends to increase the skin dose received b...
متن کاملProperties of multielectron bubbles in liquid helium
of a bubble (F is the diele~tric onstant of liquid helium) gives the class~cal *'Coulomb radius" of the bubble (this value is accurate for the bubbles considered ( 5 , 6)). For typical charges Z of 10510' electrons, this yields radii between 10 and 100 pm. The electrons in a bubble are confined to a narrow region of only a fcw Bngstrorns width close to the bubble surface, owing to their mutual ...
متن کاملElectron transport in a quasi-one dimensional channel on suspended helium films
Quasi-one dimensional electron systems have been created using a suspended helium film on a structured substrate. The electron mobility along the channel is calculated by taking into account the essential scattering processes of electrons by helium atoms in the vapor phase, ripplons, and surface defects of the film substrate. It is shown that the last scattering mechanism may dominate the elect...
متن کاملInvestigating The Role of Helium Bag On Electron Contamination Removal Using Beam NRC
Introduction: Several studies have discussed to the electron contamination caused by the air column between the head of linac and patient for photon beams. Since it is not possible to measure the electron contamination with practical dosimetry, the Monte Carlo technique is an appropriate and accurate choice to calculate particle flounce in radiation therapy. The purpose of t...
