Claims (9)
- 線形加速器であって、
複数の加速キャビティであって、隣り合う一対の加速キャビティが連結キャビティを介して連結され、少なくとも1つの連結キャビティが、当該連結キャビティにより得られる連結を変化させるよう回転自在な回転非対称部材を有するような、複数の加速キャビティと、
線形加速器の動作を制御するよう設置され、前記回転非対称部材の回転を制御するような制御手段と、
を備え、
前記制御手段は、パルス方式により前記線形加速器を作動し、一対のパルス間で前記回転非対称部材を回転させて連続するパルスのエネルギーを制御するようになっていることを特徴とする線形加速器。 - 前記回転非対称部材は、線形加速器が作動する間、連続的に回転することを特徴とする請求項1記載の線形加速器。
- 前記制御手段は、前記回転非対称部材の角度に対する、連続するパルスの位相を調節することを特徴とする請求項2記載の線形加速器。
