The tube must fit the diameter of the prosthetic aperture. Ethical Considerations and Terminology
Nevertheless, for one-dimensional, low-noise electron current measurement in steady-state plasmas, the Schamel tube remains an elegant solution. Some research groups continue to use refurbished or custom-designed Schamel tubes because no commercial off-the-shelf product replicates its exact noise performance in a B-field. shemel tube
In the realm of experimental physics, the ability to detect and amplify weak signals is paramount. While photomultiplier tubes (PMTs) and channeltrons dominate commercial markets, specialized instruments like the (or Schamel electron multiplier) occupy a crucial niche. Developed by Wolfgang Schamel, this device is an electrostatic electron multiplier used primarily for detecting low-energy electrons in plasma environments, particularly in magnetic fusion research and space plasma simulation. Unlike standard devices that rely on continuous dynode structures, the Schamel tube offers a unique design that prioritizes low-noise operation and high sensitivity in cryogenic or ultra-high vacuum (UHV) conditions.
