Abstract

La presente invención divulga un dispositivo compacto capaz de producir rayos X duros de energía mayores que 200 keV, de no menor intensidad que las fuentes de rayos X tradicionales. En la fuente propuesta, los electrones inyectados por un extremo de tina cavidad resonante metálica cilíndrica sometida al vacío se aceleran por microondas de un modo TE(p=1,2,3...) de polarización lineal o circular. Sin embargo, la sección transversal de la cavidad también puede ser elíptica, excitada con el modo TE(P=1,2,3,...), e incluso rectangular excitada con cualquier modo TE; donde p=1,2,3....Para mantener el régimen de auto resonancia a lo largo de las trayectorias helicoidales de electrones dentro de la cavidad, se genera un campo magnético estático no homogéneo cuya intensidad se aumenta principalmente en la dirección de propagación de los electrones con un perfil que depende de la energía de inyección del haz y la amplitud del campo de microondas. El haz de electrones se acelera de manera ciclotrónica auto resonante desde su inyección en la cavidad hasta que impacte sobre un blanco. La trayectoria del haz es helicoidal y su aceleración se produce en condiciones de auto resonancia. Por lo anterior, la efectividad de la utilización de la potencia de microondas es la máxima posible. Para una frecuencia dada, cuanto mayor es el subíndice p, mayor energía puede ser transferida a los electrones.
