在德国汉堡的DESY为奥林巴斯实验开发了一个内部氢靶系统。目标由一个长,薄壁,管状电池在铝散射室。氢气从电池的中心进入,并通过末端排出,在那里它被多级泵送系统从光束线上移除。低温冷头冷却目标电池以抵消光束的加热并增加目标中氢的密度。一个固定的准直器保护细胞免受同步辐射和光束晕。一系列尾流场抑制器减少了光束尾流场的加热。目标系统安装在多丽丝存储环内,并在2012年奥林巴斯实验过程中成功运行。报告了有关目标系统的设计、制造和性能的信息。
An internal hydrogen target system was developed for the OLYMPUS experiment at DESY, in Hamburg, Germany. The target consisted of a long, thin-walled, tubular cell within an aluminum scattering chamber. Hydrogen entered at the center of the cell and exited through the ends, where it was removed from the beamline by a multistage pumping system. A cryogenic coldhead cooled the target cell to counteract heating from the beam and increase the density of hydrogen in the target. A fixed collimator protected the cell from synchrotron radiation and the beam halo. A series of wakefield suppressors reduced heating from beam wakefields. The target system was installed within the DORIS storage ring and was successfully operated during the course of the OLYMPUS experiment in 2012. Information on the design, fabrication, and performance of the target system is reported.
