BEPC电子直线加速器束流线改进和e,π试验束
A Test Beam Upgrade Based on the BEPC-LINAC
【摘要】 在BEPC电子直线加速器上建立起了E1,E2 ,E3试验束 ,其中E1初级束专门提供给强流慢正电子装置应用 ,E2束是初级正 /负电子束 ,E3为次级高能e± ,π± 和质子等单粒子试验束 ,其动量连续可调 .粒子定位误差 0 .2— 0 .4mm ,混合负粒子计数率 3— 4Hz .已成功地为BESⅢ的TOF探测器模型测试提供试验束流 .
【Abstract】 A total of three beam lines, E1, E2 and E3 have based on the LINAC of BEPC. The E1 beam is to be used for intense slow-positron facility. The E2 is a primary positron or electron beam with an energy of 1.3—1.5GeV. The E3 is a secondary electron or pion test beam with a momentum can be adjustable continuously. The position accuracy of a detected particle is 0.2—0.4mm with an event rate of 3—4Hz.This beam has been successfully used for some detectors beam test.
