摘要

摘要:
高能同步辐射光源（HEPS）是中国第一台第四代高能同步辐射光源，其加速器由直线加速器、增强器、储存环及输运线组成。报道了HEPS直线加速器的初期束流调试重要进展。HEPS直线加速器是一台500 MeV S波段常温直线加速器，由热阴极电子枪、聚束系统、主直线加速器构成。在按时完成设备加工、安装和老练的基础上，于2023年3月9日启动束流调试，当天实现束流全线贯通。3月14日束流能量达到500 MeV，束团电荷量达到2.5 nC。经过测量，直线加速器出口束流能散0.4%，能量稳定度0.06%，水平和垂直几何发射度分别为233 nm和145 nm。目前直线加速器束团电荷量可达到7.0 nC，相关束流调试正在进行。

Abstract:
The High Energy Photon Source (HEPS) is the first fourth-generation synchrotron radiation source that will operate in high energy region in China. The HEPS accelerator consists of a linear accelerator, a booster, a storage ring and three transfer lines. This paper presents important progress on the HEPS Linac. The 500 MeV Linac has been constructed using S-band normal conducting structures, including a thermionic cathode electron gun, beam bunching system, and main accelerating section. After completing the equipment installation and high-power RF conditioning, the beam commissioning was started on March 9, 2023. The beam was successfully transferred to the end of the Linac on the same day, and a beam with 500 MeV of energy and 2.5 nC of pulse charge was achieved within 5 days. As measured up to date at the Linac exit, the beam energy spread and energy stability are 0.4% and 0.06% respectively, and the horizontal and vertical geometric emittances are 233 nm and 145 nm, respectively. The maximum bunch charge reaches up to 7.0 nC. Further beam commissioning will be implemented to gain full performance of the Linac.
