2010年串列加速器升级工程初步设计获得正式批复。100MeV强流回旋加速器各关键系统的施工图设计陆续完成,主要设备的加工、订货工作进展顺利。随着各系统的冷却水路和热功率参数的固化,循环水冷系统的相关工作也取得了满意的进展。其进展主要包括以下几方面。1)配合高频谐振腔功率实验,研制了相应的循环水冷机组和配水柜,满足了高频谐振腔高功 2010 tandem accelerator upgrade project preliminary design was officially approved. 100MeV strong flow cyclotron key system construction design completed one after another, the main equipment processing, ordering the progress of the smooth. With the solidification of the cooling water channels and thermal power parameters of various systems, the relevant work of the circulating water cooling system has also made satisfactory progress. Its progress mainly includes the following aspects. 1) With the high-frequency resonant cavity power experiment, developed a corresponding circulating water-cooled units and distribution cabinets to meet the high-frequency resonant cavity high power
