2. Question 1 for accelerator similar as iBNCT
Could we control the DTL cooling water temperature by detecting the detuned frequency of DTL cavity, using the same formula as that for RFQ?

Tin_autoset = Tin_mon + Gain_temp*(Tcav_aver_set - Tcav_aver_mon)
Tin_autoset = Tin_mon + Gain_temp*(Detuning_set- Detuning_mon)/Sensitivity_temp
We already did.
