Using iccd as a fast optical switch to measure harmonic super-radiation from an optical klystron in a storage ring

摘要: 用高通断比ICCD作为快速光开关,在中国科学技术大学的800MeV电子储存环上建造了一套光学速调管谐波超辐射测量系统,从每隔106个自发辐射脉冲1个谐波超辐射脉冲所形成的脉冲链里选出超辐射脉冲,测量谐波辐射的相干增强因子和谱宽。Abstract: An optical klystron is built in the 800 MeV electron storage ring at University of Science and Technology of China for harmonic super-radiation generation. In single bunch operation mode the repetition rate of the spontaneous radiation pulses is about 4.533MHz, and the repetition rate of the seed laser pulses is about 3Hz, while the radiation pulse width is 300ps. For measuring harmonic radiation a high on/off ratio ICCD is used as an optical switch to reject spontaneous radiation pulses of high repetition rate.
