Langmuir Probe

The Langmuir Probe, realized by the Center for Space Science and Applied Research of the Chinese Academy of Science, allows to:

• monitor the global parameters of the ionosphere in situ
• study the coupling between lithosphere and ionosphere before, during and after earthquakes

It consists of a pair of spherical Langmuir Probes with diameters of 5 cm and 1 cm, respectively, installed at the tip of booms 50 cm long. The LP has been tested in an Electronics test facility for an electronics calibration and in the INAF-IAPS Plasma Chamber.
