COMPACT -- the future complex plasma facility for the ISS — •Daniel P. Mohr1, Christina A. Knapek1, Stefan Schütt1, Daniel Maier1, André Melzer1, and COMPACT Collaboration2 — 1University of Greifswald, Institute of Physics, Greifswald, Germany — 2International: CA, US, SE, DE
Complex, or dusty, plasmas consist of micrometer-sized grains that are injected into a low-temperature noble gas discharge. The grains become charged and interact with each other via a screened Coulomb potential. On ground, gravity compresses the system and prevents the formation of larger, three-dimensional particle clouds.
The future complex plasma facility COMPACT will allow the investigation of large three-dimensional complex plasmas under microgravity conditions aboard the International Space Station (ISS). Its technology is based on preliminary studies (Ekoplasma, PlasmaLab), including a novel plasma chamber with adaptive internal geometry, a four-electrode radio-frequency system for plasma generation, and a stereoscopic particle diagnostic that enables the 3D particle dynamics to be recorded in real time. COMPACT is a project with international scientific contributions, funded by space agencies (DLR, NASA). A phase 0/A study is currently underway in collaboration with the space industry and will be finished until 02/2024.
We will present the scientific objectives of COMPACT, scientific and technological progress and the project status.
This work is funded by DLR/BMWi (FKZ 50WM2161).
