In the CYCIAE-230 superconducting cyclotron beam line, a vacuum system capable of providing a pressure of about 5·10-4 Pa is required for particle beam transport. In order to provide adequate interlocking to safeguard the vacuum environment and ensure the regular transmission of particles within the beam line, a vacuum control system based on programmable logic controller (PLC) has been developed and integrated into the accelerator monitoring system. The PLC not only interfaces with the quick-acting relay based on interlocking signals but also interfaces with the equipment based on Profibus communication to monitor and control various parameters in the vacuum system, such as pump speed, vacuum pressure reading, valve status, water cooling status, etc. This work presents the structure and interface logic necessary for communication with a series of valves, vacuum gauges, and molecular pump controllers. Also presented is an interface approach between vacuum control and the rest of the accelerator control system.

The China Institute of Atomic Energy (CIAE) in Beijing has designed and established a proton therapy facility based on a superconducting cyclotron CYCIAE-230, which can provide proton beams with energy from 70 MeV to 230 MeV for cancer treatment. As the most critical and core part of the proton therapy system, therapy control system (TCS) consists of various components, each of which has corresponding processing services. Motion control of external hardware systems is one of the essential parts of TCS development, and adapters figure prominently in the interaction between services and these external hardware systems. One of the adapters, called robot adapter, is specially developed for the external robotic couch system, which is a vital equipment that directly contacts patients in the whole process of proton therapy. This adapter serves as the connection between TCS and robotic couch for communication and corresponding movement. In this paper, we introduced the communication protocols, design, and characteristics of robot adapter as well as the actual test contents and results with the robotic couch. The test results indicated that the robot adapter can satisfy the needs of couch motion control and status monitoring.
