The free-electron laser FELIX at the FOM Institute for Plasma Physics Rijnhuizen

## 原理

${\displaystyle \lambda _{r}={\frac {\lambda _{u}}{2\gamma ^{2}}}\left(1+{\frac {K^{2}}{2}}\right)}$

K的值相當小時，可被簡化為：

${\displaystyle \lambda _{r}\propto {\frac {\lambda _{u}}{2\gamma ^{2}}}}$

${\displaystyle \lambda _{u}}$ 是聚頻磁鐵/波荡器的波長

${\displaystyle \gamma }$ 是相對勞侖茲因子及由聚頻磁鐵/波荡器的幾何參數決定的比例常數
