   The Large Plasma Device during an experiment. The Large Plasma Device (often stylized as LArge Plasma Device or LAPD) is an experimental physics device located at UCLA. It is designed as a general purpose laboratory for experimental plasma physics research. The device began operation in 1991 [1] and was upgraded in 2001 [2] to its current version.

   How does a LAPD machine produce plasma?

   • The machine is under vacuum but the plasma discharge is turned off. The main source of plasma within the LAPD is produced via discharge from the barium oxide (BaO) coated cathode, which emits electrons via thermionic emission.

   What is the main source of plasma within the LAPD?

   • The main source of plasma within the LAPD is produced via discharge from the barium oxide (BaO) coated cathode, which emits electrons via thermionic emission. The cathode is located near the end of the LAPD and is made from a thin nickel sheet, uniformly heated to roughly 900 °C.

   Plasma is called the fourth state of matter after solid, liquid, and gas. [16] [17] [18] It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.

   Feb 9, 2016 · The Large Plasma Device (LAPD) was upgraded in 2001 and has become a national user facility for the study of basic plasma physics. The upgrade as well as diagnostics introduced since then has significantly changed the capabilities of the device. All references to the machine still quote the original RSI paper, which at this time is not appropriate.
