The beam stability is the precondition for physical experiments and cancer curing in the applications of heavy-ion accelerator. Domestic and foreign studies show that the temperature has a great impact on the beam stability. Some scholars have suggested that when the air temperature varies in about 3 ℃, the monitor dose will change about 1%[1]. There also has a strong correlation between environment temperature and beam position. When the temperature changes in 1 ℃, the beam position in vertical direction will change 10~20 μm[2].
