QED-1

The Quiet-Energetic-Dense (QED-1) device was an arcjet linear device located at PPPL. It had a length of 1.6 m and a radius of 0.1 m. It could achieve up to 0.6 T magnetic field and electron and ion temperatures of 15 eV. The electron densities were between 10¹⁸ and 10²¹ m^-3. It was built to improve the understanding of plasma stability in high density plasmas and was an improved version of a similar device constructed in UCLA.
