Основные научные положения, сформулированные автором на основании проведенных исследований:
  1. Разработка МПГК на подложках с электронной проводимостью с быстродействием свыше 106 частиц·с-1·мм-2, способных устойчиво работать при высоких давлениях и обладающих высокой радиационной стойкостью в отсутствии потоков адронов.
