Self ordering to imposed ordering of dust -- a continuous spatial phase transition experiment in MDPX
Siddharth Bachoti, Saikat Chakraborty Thakur, Rahul Banka +2
Previous experiments conducted in the Magnetized Dusty Plasma eXperiment (MDPX) revealed an intriguing phenomenon first referred to as imposed ordering. This occurs when micron-siz…
Non-perturbative 2D spatial measurements of electric fields within a plasma sheath
Mykhailo Vorobiov, Rob Behary, Will Torg +9
We introduce an all-optical quantum-enhanced diagnostic for electric fields in low-temperature plasmas. Trace amounts of rubidium vapor, added to argon plasma, allow us to produce…
Plasma fibre using bright-core helicon plasma
Lei Chang, Zi-Chen Kan, Jing-Jing Ma +2
This paper reports an innovative concept of ``plasma fibre" using bright-core helicon plasma, inspired by its spatial and spectral similarities to the well-known optical fibre. The…
Transition of blue-core helicon discharge
L. Chang, S. J. Zhang, J. T. Wu +10
This study explores the transitional characteristics of blue-core helicon discharge, which to our knowledge was not particularly focused on before. Parameters are measured on recen…
The CHIMERAS Project: Design Framework for the Collisionless HIgh-beta Magnetized Experiment Researching Astrophysical Systems
S. Dorfman, S. Bose, E. Lichko +11
From the near-Earth solar wind to the intracluster medium of galaxy clusters, collisionless, high-beta, magnetized plasmas pervade our universe. Energy and momentum transport from…
Experiments and modeling of dust particle heating resulting from changes in polarity switching in the PK-4 microgravity laboratory
Lori S. McCabe, Jeremiah Williams, Saikat Chakraborty Thakur +6
In the presence of gravity, the micron-sized charged dust particles in a complex (dusty) plasma are compressed into thin layers. However, under the microgravity conditions of the P…
