TUP15	Control System Dedicated for Beam Line of Proton Radiography on 100 MeV Cyclotron CYCIAE-100	202

	After the first beam on July 4 2014, CYCIAE-100's performance have been improved gradually and is ready for routine operation. There are 7 beam lines in total in the design stage, i.e. N1:ISOL, N2:isotope production, N3:beam dump, S1: single energy neutron, S2:white light neutron source, S3: radiobiological effect, S4:single event effect. The beam lines N2 and N3 were combined into one line during the construction. In the last two years, we propose to build to two new lines, one for principle verification of Proton Radiography, the other one for demonstration of proton therapy. Both of them are quite special. In this paper, a control system for the operation of the beam line of proton radiography, including the magnets, vacuum and water cooling, the beam intensity & profile diagnostics, and the imaging etc, will be presented.

TUP16	The High Quality Water Cooling System for a 100 MeV Cyclotron	205

	A high quality water cooling system with total heat power dissipation of 500 kW has been built and successfully used for a 100 MeV high intensity Cyclotron. The main features of this system are high water quality with specific conductivity bellow 0.5 μS/cm, high cooling water temperature stability better than ±0.1°C for long time operation and much electric power-saving in comparing with classical design. For some special usages, such as high beam power target and vacuum helium compressor, they all are well treated and reasonably separated from the main cooling system. There are totally 108 distributed water branches together for different sub-equipments of the cyclotron. At each branch, there are one water flow switch for safe interlock, one flow meter for monitoring, one temperature sensor for remote diagnostics. The water cooling system is under automatic control with PLC, and its operation status and all parameters can be remotely monitored from the control room. All of the involved equipments can be switched on/off by one key, no on-duty staff is needed at normal conditions. This system has been put into commissioning for two years and proved successful and reliable.

A proof-of-principle test-stand for proton radiography is under construction at China Institute of Atomic Energy (CIAE). This test-stand will utilize the 100 MeV proton beam provided by the compact cyclotron CYCIAE-100, which has been built in the year of 2014, to radiograph thin static objects. The assembling of the test-stand components is finished by now. We will carry out the first proton radiography experiment in this July and hopefully we can get the first image before the opening of this conference.
