Claims (5)

  1. 一種放射線光束監控裝置，係具備：金屬製框體，在放射線的入射側設有窗；高分子窗膜，將前述窗從前述框體的外側予以覆蓋；密封構件，將前述窗的周圍從前述框體的內側予以包圍；金屬製窗膜，將前述窗從前述框體的內側予以覆蓋，且透過前述密封構件而固定於前述框體；第1屏蔽膜(shield film)，與前述窗膜對向配置且設定為與前述框體相同電位；第1金屬膜，配置在較前述第1屏蔽膜更靠前述放射線之下游側且接受電壓的施加；第2金屬膜，配置在較前述第1金屬膜更靠前述放射線之下游側且接受電壓的施加；信號電極，配置在前述第1金屬膜與前述第2金屬膜之間，且連接於測量器；及第2屏蔽膜，配置在較前述第2金屬膜更靠前述放射線之下游側且設定為與前述框體相同電位。
  2. 如申請專利範圍第1項所述之放射線光束監控裝置，其中，在前述框體中，係於前述放射線之出射側設有窗，且具備：出射側的高分子窗膜，將前述出射側的窗從前述框體的外側予以覆蓋； 出射側的密封構件，將前述出射側之窗的周圍從前述框體的內側予以包圍；及金屬製之出射側的窗膜，將前述出射側的窗從前述框體的內側予以覆蓋，且透過前述出射側的密封構件而固定於前述框體。
  3. 如申請專利範圍第1項所述之放射線光束監控裝置，該裝置係具備配置在較前述第2屏蔽膜更靠前述放射線的下游側，用以吸收前述放射線的塊體(block)。
  4. 如申請專利範圍第1項所述之放射線光束監控裝置，其中，前述信號電極係由金屬膜所構成。
  5. 如申請專利範圍第1項所述之放射線光束監控裝置，其中，前述信號電極係具有由並聯排列的複數條線(wire)所構成的第1線群、及由並聯排列的複數條線所構成的第2線群，前述第1線群與前述第2線群係隔開間隔配設在彼此正交的方向。
