摘要

<正>A pellet target facility with global detectors will be constructed at CSRm, Lanzhou for hadron physics research. The pellet diameter ranges from 25 to 35 μm, and thus an effective target thickness of 1015 - 1016 atoms/cm2 is expected. The number of stored particles in CSRm is estimated to be 1×109 particles per cycle with the existing accelerator(s) as the injector. With the aid of a planned booster as the injector, the maximum stored particles per cycle can be elevated to 1×1012. The revolution frequency is typically in the order of 1 MHz for the present CSRm ring with a circumference of 161.0 m. With the new booster, a maximum experimental luminosity for pellet target is estimated to be 1×1034/(cm2·s).
