The scintillation CsI was also calibrated with protons of 15, 20, 23MeV. The average energy calibration is 1. 047MeV per channel. Energy calibration for heavy ions was completed with multiplication factor 1/12. 75. The energy calibration is around 1. 1MeV per channel for oxygen ion and iron ions when energy deposition is less than 50MeV in each detector.

对铁离子而言，铁离子的四个能量点在ΔE〓探测器中的能量均超过50MeV，能量信号放大电路此时已进入饱和状态，当铁束能量为120MeV时，离子进入到ΔE〓探测器中，此时在ΔE〓中能量沉积低于50MeV，没有达到电子学系统的饱和值，能量刻度每道为1.1MeV／道，这些与氧离子的标定结果是一致的，饱和只是对于低能重粒子会出现这种情况，对于中高能重离子这种现象就会消失。
