Electron Temperature Observed with the Langmuir Probe and Electron Temperature Probe

Intercomparison between the Langmuir probe and the electron temperature probe which has been developed by the authors, in the measuring of the electron temperature, was carried out two times by using two rockets, K-9M-28 and K-9M-29.The difference between the results obtained with two probes will be discussed and the inconsistency between the electron temperature obtained with the rocket probe and the Thomson scattering method will be also discussed.
