摘要:

使用相干跃迁辐射自相关方法来确定聚束长度和轮廓信息的检查与压缩电子束在BNL ATF。一个双高斯拟合应用于相干渡越辐射自相关数据提取纵向电流分布。大的横向梁尺寸的影响进行了理论研究,并与实验结果进行了比较。一个合适的形式的校正因子推导出梁与大的横向纵向纵横比。

英文摘要:

The use of coherent transition radiation autocorrelation methods to determine bunch length and profile information is examined with the compressed electron beam at the BNL ATF. A bi-gaussian fit is applied to coherent transition radiation auto-correlation data to extract the longitudinal current distribution. The effects of large transverse beam sizes are studied in theory and compared to experimental results. A suitable form of the correction factor is derived for beams with large transverse-longitudinal aspect ratios.
