HET (Hall Effect Thruster)

A Hall Effect Thruster (HET) is a type of electric propulsion device used for spacecraft. It works by ionizing a propellant, usually xenon gas, and using magnetic and electric fields to accelerate these ions out the back, producing thrust. The magnetic field traps electrons, creating a Hall current that helps sustain the ionization process. When ions are expelled at high speeds, they generate a gentle but continuous push, allowing spacecraft to maneuver efficiently in space. HETs are valued for their high efficiency and ability to provide sustained thrust over long durations, making them ideal for deep-space missions.
