For the high current injector project at Inter University Accelerator Centre, a high temperature superconducting electron cyclotron resonance (ECR) ion source, PKDELIS, would provide the high charge state ions. The emittance of the ECR ion source is an important parameter to design further beam transport system and to match the acceptances of the downstream radio frequency quadrupole and drift tube linac accelerators of the high current injector. The emittance of the analyzed beam of PKDELIS ECR source has been measured utilizing the three beam size technique. A slit and two beam profile monitors positioned at fixed distances from each other were used to measure the beam size. The digitized beam profiles have been analyzed to determine the emittance of various multiply charged ions. The variation of emittance with gas mixing, ultrahigh frequency power, and extraction energy are discussed in this presentation.
对于大学间加速器中心的强流注入器项目，一台高温超导电子回旋共振（ECR）离子源PKDELIS将提供高电荷态离子。ECR离子源的发射度是设计后续束流传输系统以及匹配强流注入器下游射频四极杆和漂移管直线加速器接受度的重要参数。已利用三束斑尺寸技术测量了PKDELIS ECR源分析束的发射度。使用一个狭缝和两个相互间隔固定距离的束轮廓监测器来测量束斑尺寸。对数字化的束轮廓进行了分析，以确定各种多电荷离子的发射度。本报告讨论了发射度随气体混合、超高频功率和引出能量的变化情况。
