The cryogenic control system of SHINE

AbstractThe Shanghai High repetition rate XFEL and Extreme Light Facility (SHINE), an advanced XFEL project, is now being built at Shanghai Advanced Research Institute (SARI), Chinese Academy of Sciences. It includes a hard X-ray free electron laser and a 100 pW intense laser facilities with overall length of 3.1 km. The XFEL part including an 8 GeV LINAC and 3 undulator lines is cooled with forced superfluid and supercritical helium at 2 K/4 K. The cryogenic system of SHINE consists of test facility cryogenic system (TFCS), accelerator cryogenic system (ACCS), and undulator cryogenic system (UNCS). A dedicated control system based on Experimental Physics and Industrial Control System (EPICS) will be built to automate the cryogenic system with process control, PID control loops, real-time data acquisition and storage, alarm handler and human machine interface. It is capable of automatic recovery as well. This paper describes details of control system structure, interfaces, controllers and the integration under EPICS framework.

For the engine maintenance enterprises, the test of aeroengine test can detect the performance of the product more accurately, but the engine testing work is a weak link. Conventional piston aircraft engine test system is the simulation instrument, according to the observed by human eyes, manual way to complete data collection work, this test system is inefficient. The engine bench test automatic measurement and control and monitoring system based on computer control is the inevitable trend of its development. Data acquisition module transmits the real-time data from the engine sensor installed on the different parts to the PC through CAN bus and display on the PC. The engine test bed control system and data acquisition system simplifies the system structure and obviously improves the test level and efficiency of the system.

Background & Objective: Wireless networks are making its way for use in industrial control system applications. The installation of Wireless networks naturally provides a reduction in cable and its maintenance related costs, provides increased flexibility and mobility to enhance the performance of industrial control system. Method: This paper attempts to show the suitability of a wireless network in control system application of ECRH system at IIGTF. IEEE 802.11n network is implemented to interface field instruments with PLC based control system in an industry like environment. The two case studies with different control architecture are implemented with satisfactory test results. The first case demonstrates the use of a wireless network for monitoring and data acquisition of cooling water process parameters. The second case implements the control and monitoring of the DC power supply over the wireless network through a serial ASCII protocol. The performance of wireless communication alone in is evaluated using theoretical analysis, simulation and actual field measurement. Then overall performance of the case studies including field signals and PLC system is evaluated. Conclusion: The PLC application logic is developed for the implementation of logic functions to interface various field instruments and power supply. The DC power supply is simulated using Labview ™ for serial ASCII communication. The above said concept is proposed for the Local Control Unit being developed for ITER-India Test Gyrotron Facility.
