EFI LP probes on Swarm C both set to high gain during TII inactive periods

15 February 2018

We inform the Swarm users that starting from 02 October 2017, both EFI Langmuir Probes (LPs) on Swarm C are systematically set to high gain during EFI TII inactive periods.

The declining solar activity has resulted in on average smaller probe currents. Preliminary results have shown that the quality of the electron density and temperature estimates is good.

After confirming this with further and systematic investigations it is planned to operate the LPs on the higher Swarm B in this mode.
