Summary
A theoretical analysis of the bremsstrahlung resulting from the passage of a beam of electrons through polar gases has been made. Analytical expressions for the total power and the frequency distribution of the emitted radiation have been determined. The results have been expressed as a numerical plot between a dimensionless factor and the dimensionaless frequency. Kirchhoff’s law has been used to derive the electrical conductivity due to the free-free radiation from a Maxwellian distribution of electron velocities. The work should find application in a number of situations involving the passage of electrons through polar gases.
Riassunto
Si è svolta un'analisi teorica dell'effetto di bremsstrahlung dovuto al passaggio di un fascio di elettroni attraverso gas polari. Si sono determinate espressioni analitiche per la potenza totale e la distribuzione di frequenza della radiazione emessa. Si sono espressi i risultati come un diagramma numerico tra un fattore adimensionale la frequenza adimensionale. Si è usata la legge di Kirchhoff per desumere la conducibità elettrica dovuta alla radiazione fra elettroni liberi da una distribuzione maxwelliana delle velocità degli elettroni. Il lavoro è passibile di applicazioni in numerose situazioni che coinvolgano il passaggio di elettroni attraverso gas polari.
Резюме
Ъыл проведен теоретический анализ тормозного излучения, возникаюшего при прохождении пучка электронов через полярные газы. Ъыли определены аналитические выражения для полной интенсивности и для частотного распределения возникаущего излучения. Полученные результаты представлены в виде числовой зависимости безразмерного фактора от безразмерной частоты. Закон Кирхгофа был использован для вывода электрической проводимости вследствие излучения из максвелловского распределения скоростей электронов. Эта работа должна найти применение в ряде ситуаций, включающих прохождение электронов через полярные газы.
