Abstract: | Pellet target is one of the main candidate targets in CSRm (cooler storage ring’s main ring) for hadron physics studies. Pellet
speed is an important physical parameter for the target. Larger pellet speed could shorten the interacting time interval between
the pellet and the cyclotron beam, and thus results in a small temperature variation for the pellet. This could make the pellet
facility work in a stable condition. A fluid dynamic simulation was carried out for the pellet speed, and it was found that
the maximum speed for the target pellet may be restricted to about 100 m/s even if all working parameters were set to their
optimal values.
