Title: 두 개 이상의 rf 소스로 조직을 조사하기 위한 양성자 선형 가속기 시스템
Inventor: NAVARRO QUIRANTE JOSE LUIS
IPC: H05H7/02
Filed: 2019-04-24
Abstract: 양성자 빔은 암세포를 파괴할 수 있지만 건강한 조직에 대한 손상이 크게 감소하기 때문에 치료 목적으로 X 선에 대한 유망한 대안이다. 조직의 에너지 선량은 종양에 근접하게 브래그 피크를 위치시키도록 빔을 구성함으로써 종양 부위에 집중될 수 있다. 조직에서 양성자 빔의 길이 방향 범위는 일반적으로 빔의 에너지에 따라 다르다. 그러나, 에너지를 전환한 후, 양성자 빔 시스템은 치료에 사용되기 전에 빔 에너지가 안정화되는데 소정의 시간이 필요하다. 양성자 빔의 에너지를 변경하기 위한 양성자 빔 작동 사이클의 온-타임 동안 제 1 RF 에너지 소스로부터 F 에너지를 제공하도록 그리고 공동의 온도를 증가 또는 유지하기 위해 양성자 빔 작동 사이클의 오프-타임 동안 제2의 별개의 RF 에너지 소스로부터 RF 에너지를 제공하도록 구성된 개선된 빔 에너지 제어로 조직을 조사하기 위해 양성자 선형 가속기 시스템이 제공된다. 각각의 RF 소스는 독립적으로 작동하여 더 높은 RF 펄스 속도가 공동에 도달할 수 있으므로, 양성자 빔 에너지 펄스들 사이를 더 짧은 시간을 지지한다. 또한, 제 2 RF 에너지 소스에 대한 피크 전력 요건은 일반적으로 제 2 RF 에너지 소스에 대한 것보다 적을 수 있으며, 제 2 소스에 대해 더 저렴한 유형을 사용할 수 있다. 제 1 및 제 2 RF 소스를 사용하면 캐비티 정정 시간을 몇 분에서 10초 미만으로 줄일 수 있다.
