Анотація

Проведено розрахунок фазового зсуву при iнтерферометрiї плазми похилими мiкрохвилями та крiзь центр плазмового утворення. Розраховано значення критичного радiуса rcr плазмового шару з густиною рiвнiй Ncr, для рiзноманiтних функцiй розподiлу вздовж радiуса, коли мiкрохвильовi променi не потрапляють до антени. Експериментально отримана часова залежнiсть змiни фазового зсуву для наскрiзного та похилого зондування. З фазових зсувiв, вимiряних обома iнтерферометрами, визначено залежнiсть добутку NpL (Np – концентрацiя електронiв плазми, L – довжина оптичного шляху мiкрохвильового променя в вакуумi) у часi, а також оцiнено величину середньої густини плазми.
