Vector Tomographic Reconstruction of 3D Plasma Flows with Ion Doppler Spectroscopy

A laboratory astrophysical jet experiment is being constructed to investigate the dynamics of canonical flux tubes. This poster will present a vector field diagnostic able to measure 3D ion flows from spectroscopic Doppler shifts based on vector tomographic reconstruction techniques [1]. The Ion Doppler Spectroscopy (IDS) setup consists of a 1.0m Czerny-Turner monochromator, a dual-inline frame Princeton Instruments PIMAX-3 (1024 x 1024) iCCD camera, collimating optics, matching optics, and a fiber bundle. The fiber bundle is designed to group 48 optical detector arrays of 14 chords each, totaling 672 lines of sight, into a 2D iCCD image. The mounting hardware is designed to position the fiber arrays spherically around the plasma.\\[4pt] [1] A. L. Balandin, Y. Ono and S.
