| WEP22 | The Lens Effect in the Secondary Emission Based Systems of Joint Searching in EBW | electron, gun, experiment, FPGA | 83 |
|
|||
| The results of developed scan lines generator for the magnetic correctors system are presented. Get the dependency between various types of the scan lines and distribution of the allocated energy in the electron beam welding facility. The lens effect in the secondary emission based system of joint searching, using 3-fragment linear scan line is received. The accuracy of the joint searching system (the error of positioning system) is 0.05 mm, the lens effect can decrease this value several times. The requirements for the creation full calibrated system of joint searching are listed. | |||

| WEP34 | The Control System based on EPICS for the Experimental Target Prototype | controls, EPICS, experiment, PLC | 116 |
|
|||
| Building a high power spallation target is one of the critical issues in Accelerator Driven System (ADS). The control system which was built based on the real-time distributed control software of experimental physics and industrial control system (EPICS) was attempted for the experimental target prototype. There are several sub-systems in the target system, e.g. the elevating system, the vacuum system, the heat-exchanging system. As an IOC, each sub-system was finally integrated into the control system of the target by different drivers and methods because different hardware devices were used for each sub-system. The ’SLS s7 driver’ which was devel-oped based on the Ethernet Interface was used for the communication between the Siemens PLCs and the Hu-man Machine Interface (HMI). The interfaces between Labview and EPICS were used for the NI (Nation-al Instruments) DAQs systems. In addition, the driver developed by ourselves was used for devices with serial ports, e.g. RS-232 or RS-485/422. The control system was finally proved stable and could basically meet the ele-mentary requirements of the spallation target system. | |||

| THP02 | Current Status of the RAON Machine Protection System Development | operation, PLC, controls, machine-protect | 160 |
|
|||
| For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans. | |||

| THP22 | Guaranteeing the Measurement Accuracy in Em#* | impedance, ISOL, synchrotron, FPGA | 216 |
|
|||
|
ALBA, in collaboration with MAXIV, has developed a four-channel electrometer of 18bit deep with 8 ranges from 1mA to 100pA. The objective of accuracy in the measurements made clear from the beginning the need to compensate the components tolerances and its dependence with temperature. This paper describes the tests performed to characterize the acquisition chain, the automatic calibration developed and the hardware and software implemented to achieve the accuracy target. This implementation has been eased due to the high flexibility given by ALIN and Harmony** architectures used in the Em#.
