Astrophysics Application
Most of the observable matter in the universe has been in the plasma state. In plasma astrophysics, we aim to study and help understand how plasmas behave in stars, planetary systems, galaxies and in between them. All known astrophysical plasmas are magnetic. It is important to understand the role of turbulent motions in this vast plasma, as well as the importance of magnetic fields and relativistic particles in organizing structures and powering outflows on particle fluxes.
In this direction, scientist try to create large size magnetized plasmas in laboratory and measure their properties to understand the plasma behavior mimicking that of outer space. These plasmas are complex to monitor because of their huge size, presence of magnetic field, turbulence and gradient of density and temperature.
Impedans Langmuir probe for astrophysical plasma measurement:
The Impedans Langmuir Probe system measures key plasma parameters such as plasma potential, charged particle densities (upto 10 13 cm -3 ) and the electron temperature (upto 15 eV). This probe offers a linear drive option as well which can be used to automatically scan across the large distances and spatially characterize large size plasma upto 90 cm in any laboratory chamber. The probe also provides time trend, synchronised pulse profile and triggered fast-sweep modes with 80 MS/s sampling rate to monitor turbulences and transient nature of plasma.
