论文摘要
我们已经观察到能源沉积的显着增强$ 25 $ - $ 100〜 \ MATHRM {GEV} $光子在$ 1〜 \ Mathrm {cm} $厚实的tungsten crystal沿其$ \ langle 111 \ rangle $ lattice $ lattice axes。在$ 100〜 \ Mathrm {Gev} $的情况下，对于没有轴向对准的值，这种增强功能超过双重。这种效应以及测量的二级粒子产生的巨大增加归因于强轴向电场的电磁淋浴发育的加速。与新开发的蒙特卡洛（Monte Carlo）相比，实验结果已进行了严格的比较，该蒙特卡洛（Monte Carlo）适用于多$ x_0 $厚度的晶体。本文介绍的结果可能被证明对发展高性能光子吸收器以及高度紧凑的电磁热量器和梁储量的发展引起了重大关注。
We have observed a significant enhancement in the energy deposition by $25$--$100~\mathrm{GeV}$ photons in a $1~\mathrm{cm}$ thick tungsten crystal oriented along its $\langle 111 \rangle$ lattice axes. At $100~\mathrm{GeV}$, this enhancement, with respect to the value observed without axial alignment, is more than twofold. This effect, together with the measured huge increase in secondary particle generation is ascribed to the acceleration of the electromagnetic shower development by the strong axial electric field. The experimental results have been critically compared with a newly developed Monte Carlo adapted for use with crystals of multi-$X_0$ thickness. The results presented in this paper may prove to be of significant interest for the development of high-performance photon absorbers and highly compact electromagnetic calorimeters and beam dumps for use at the energy and intensity frontiers.
