高能 γ 光子是通过 Super-ACO 存储环自由电子激光器（350nm）和超相对论（800MeV）正电子束之间的腔内康普顿背散射（CBS）过程产生的。没有对光束进行空间选择，因此直接（NaI 探测器）和间接（CBS 正电子束寿命）研究了宽能量范围的 γ 光子。高腔内激光功率导致高 γ 光子发射率（500 万次/秒）。提出了一些未来可能的改进。
High-energy γ-photons have been produced by an intra-cavity Compton Back Scattering (CBS) process between the Super-ACO Storage Ring Free Electron Laser, at 350nm, and an ultra-relativistic (800MeV) positron bunch. No spatial selection of the beam has been made so a wide energy range of γ-photons has been directly (NaI detector) and indirectly (CBS positrons bunch life-time) investigated. The high intra-cavity laser power leads to a high γ-photons emission rate (5 millions ph/s). Some future possible improvements are proposed.
