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.
