Project summary

The main objective of the project is development methodology to carry out an experiment on the direct verification of flow cyclotron maser (FCM) in the magnetosphere and study of its properties by chemical release into the upper atmosphere from a geophysical rocket including development of the methodology of an experiment, the methods prediction of the optimal conditions for it, methods fordetection of the deterministic geophysical parameters (indicators) directly related to the FCM, on-board equipment for injection, ground-based diagnostics equipment.

Project Objectives:

  • Development of the methodology of an experiment, methods and models for detection and recording of the FCM indicators
  • Development of an empirical model of long-term (weeks), mid-term (days), and short-term (hours) forecasting the helio-geophysical situation and weather conditions for carrying out the rocket experiment and optimizing the pre-launch preparation of the rocket site

Project Narrative

Within the framework of the Project, the methodology of an experiment and technical facilities (including production of the brassboard models of the on-board equipment and ground-based diagnostic equipment) will be developed for studies of a flow cyclotron maser (FCM) in the Earth's magnetosphere with use of creation of artificial ionized cloud released by a geophysical rocket which has to be launched from the rocket range ESRANGE (Kiruna, Sweden).

During the investigation of the self-consistent theory of radiation belts a group of the project participants developed the conception of the flowing cyclotron maser (FCM) in the Earth's magnetosphere, in which energetic charged particles represent active substance, while magnetic force tubes, filled with cold plasma and limited by the ionospheres of both hemispheres serve as a resonator. The main confirmation of FCM presence in the earth's magnetosphere is the development of pulsating forms of auroras and related to them low frequency emissions of chorus type, observed during natural magnetosphere disturbances. All this is necessary, however not enough to build an accurate quantitative model of interaction of low frequency waves and particles within the FCM theory.

Therefore, is proposed to carry out research for preparing a controlled experiment, consisting in creation of an artificial ionized cloud (ionosphere mirror), which can significantly increase the reflection coefficient of low frequency waves from the ionosphere and and thus excite electron precipitation from the magnetosphere into the ionosphere and cause artificial pulsating auroras.

Successful realization of the proposed project tin future will enable us to build a quantitative model of magnetosphere-ionosphere wave and particle interaction, which stipulates the dynamics of energetic charged particles in radiation belts and to realize a rocket experiment under optimal conditions for research of this interaction

Basing on the fact that according to the developed by the authors of the Project FCM conception finding the excited pulsating precipitations of electrons simultaneously with pulsating low frequency electromagnetic emissions could be the best indicator of FCM functioning, the important task of the project is the development of methodology of observations and measurement in the dynamics of the parameters of artificially modified pulsating auroras and low frequency emissions.

The authors of the project and collaborators yet prior to the development of the FCM theory in rocket experiments first found some indicators, which were the evidence of high probability of real functioning of FCM in the magnetosphere of the Earth (detection of pulsating precipitations of particles and modification of auroras during formation of ionized barium clouds in the upper atmosphere), however, these works had been carried out without knowledge simultaneous registration of low frequency emissions, by which one could reliably judge about the cause of the stimulated precipitations and artificial auroras.

Within the framework of the project, it is planned to produce brassboard models of the on-board rocket complex for cesium injection, to fit the technical characteristics of a rocket and payload to each other, to develop new and to modify existing ground-based optical, radio-physical and geophysical measurement tools, to develop a methodology of prediction and optimal choice of the quantity of released substance, time and height of injection on the basis of estimating the possible geophysical situation. In this project it is intended to carry out experimental observations (imitation experiments) with use of the developed ground-based diagnostic equipment to determine the background (without cesium injection) dynamics of the parameters of natural pulsating auroras and accompanying geophysical effects.

This work will be of fundamental importance for physical investigation of plasma processes in laboratory and space plasmas and for the diagnosis of energetic particles in radiation belts and their dynamics upon the interactions with electromagnetic waves. An important line of applied studies in this project is the preparation active experiment under optimal and monitored conditions. This experience can be employed in future for various applied experiments in the near-Earth space.

The developed complex of equipment and methods of the carrying out the experiments could be widely used further in national and nternational projects.
