摘要

简略评述以TESLA为基础的光子对撞机研究现状与进展。给出了光子对撞机基本方案,光子(γγ)对撞和光子-电子(γe)对撞所需的高能光子,可以用激光在高能电子束上的康普顿后向散射得到。当前,光子对撞机的关键问题是高能激光系统。以二极管抽运的高平均功率的固体激光系统,通过六次循环的光学储存环,可以提供波长1.06μm,脉冲能量5J,重复率~14kHz,脉冲间隔与电子束脉冲结构匹配的高功率激光,满足光子对撞机的要求。

Abstract

This paper briefly reviews the status and advancement of photon collider based on the linear collider TESLA. The basic scheme of photon collider is given. High energy photon for γγ, γe collisions can be obtained using Compton back scattering of laser light of high energy electrons. At present, the key element in photon collider is a very powerful laser system. The light beam of the high average power solid laser system by diode pumping passing through the optical storage ring for six round trips would provide the high power laser with wavelength 1.06μm, the pulse energy 5J, the repetition rate of about 14kHz, which satisfies the request for photon collider.
