Brief Introduction

The Conditional Technology Group (CTG) provides basis supporting services for accelerator devices and is responsible for the design and maintenance of cooling-water system, air compression system and heat ventilation & air-conditioner system(HAVC). The group provide technical support and site coordination for the preliminary work of new accelerator project, such as: site-selection assessment, planning and construction application, general layout design, survey design, and all the interface of civil construction, etc.  

At present, CTG mainly undertakes the preliminary work of High Intensity heavy-ion Accelerator Facility (HIAF) and China initiative Accelerator Driven System (CIADS), viz. adjustment of feasibility study plan, feasibility study of forest & land, survey and design, bidding of construction & supervision, procedure of civil engineering approval and other interface work. Meanwhile, CTG is mainly involved in the project of High Intensity heavy-ion Accelerator Facility (HIAF), China initiative Accelerator Driven System (CIADS), Heavy Ion accelerator for medical machine (HIMM), Space Environment Simulation and Research Infrastructure (SESRI), Proton Radiation Effects Facility (PREF), etc. 

CTG has 10 in-service staff, including 1 has senior title and 6 have deputy senior title. Based on National Laboratory platform, CTG will focus on the research of water-cooling technology applied in accelerators, viz. high precision & stationary-temperature water system, tuning technology by cooled water, preparation of ultrapure water, and continuously provide more stable foundation supporting for accelerator devices.
