我们开发了一种紧凑型被动能量选择器,用于处理超短超强脉冲激光辐照固体靶产生的MeV范围电子。该装置可产生能量范围从几十keV到几十MeV、能量展宽可变的电子束。本文通过从固体靶产生MeV范围、带宽约10%的电子,展示了其应用,从而补偿了此类源产生电子的固有宽带特性。结合脉冲磁场进一步补偿该源的固有大发散度,该装置可产生高度准直、窄带且超快的电子束,适用于放射治疗、时间分辨电子探测等广泛应用。
英文摘要
We have developed a compact passive energy-selector for MeV-range electrons produced by irradiating solid targets by ultra-intense short-pulse lasers. The device allows for generating electron beams with a variable energy spread over a broad range of energies, from tens of keV to tens of MeV. Here we have demonstrated its use by producing electrons from solid targets in the MeV range and with a ~10% bandwidth, thereby compensating the intrinsic broadband nature of the electrons produced from such source. Coupled with a pulsed magnetic field to further compensate the intrinsic large divergence of this source, it allows to produce a highly-collimated beam of narrow-band and ultra-fast electrons, suitable for a wide range of applications, e.g. radiation therapy or time-resolved electron probing.
