The total operation time of HIRFL is 7 272 h in 2014, and the user beam time is about 4 964.5 h(from 21stDec.2013 to 21st Dec. 2014). 3 749 h for physics experi
The magnetic field created by dipolar magnet is very important for the quality of beam in CSRe. It is required that the magnetic fields fluctuation ranges less
