	In order to improve running efficiency of accelerator, shorten the time of changing accelerator beam is key link and it should be considered how to accelerate the ion to specific energy quickly and accurately. We will discuss how to use years of heavy ion accelerator operation data to generate a set of virtual accelerator equipment data for specific ion and energy, load to all the accelerator equipment fast. EPICS provide Channel Archiver tools that can achieve and store data from the IOC equipment operation information. In this study, we use Archive Engine tool and Oracle to combine data acquisition function and data management function. Firstly store the Archive Engine acquisition data into Oracle database, and then according to the data to create accelerator system operation snapshot as the basis for beam tuning. The snapshot data includes all equipment state and parameters at special time in accelerator operating. When the ion is to be changed, related snapshot in Oracle database will be retrieved and loaded to all the equipment and to realize efficiently beam tuning.

THPEA018	Design of an Integrated Platform based on CSS and MATLAB for SSC-LINAC System Controlling and Data Analysis	3182

	CSS is the abbreviation of Control System Studio and is widely used in particle accelerator experiments area. Based on Eclipse, it is a collection of tools which can display details of the PV, show alarm state, as well as the function of data browsers, archive engine and so on. CSS offers an integrated approach to build a control system. We have recently developed a control and monitor system for the SSC-LINAC system to control and monitor power supply, vacuum, high frequency, and other accelerator equipments. In the area of accelerator controlling, we often need to do some mathematical operations like Fourier transform of the monitored data to get some accuracy performances of interested equipments. Unfortunately, CSS cannot satisfy this requirement. It is well known that MATLAB plays very well in data process and provides many mathematical tools. If we can combine these two tools together, we can get better control strategy. In the presentation, we will discuss the design of this integrated platform to implement the display, control and data process.

	A method of implementing controls of chopper for HIRFL-CSR (Heavy Ion Research Facility of Lanzhou and Cooler Storage Rings) is introduced. This method is based on an ARM and DSP co-operation system. The control algorithm of this method is based on a data structure which is defined and implemented in the DSP module. Output data is created by the control algorithm and the actually pulse output is triggered by a timer which is achieved through a logic circuit actualized in a FPGA chip. The results show that the method is flexible and the control system matches the chopper regulating requirements.

	This article introduces the structure of power supply in HIRFL(Heavy Ion Research Facility in Lanzhou) and designs a program which can preset power supply data automatically. We use Labview which is produced by NI Corporation to read Excel, access the Oracle database and send the generated instructions to power supply controllers. This program brings great convenience to physicists. It is used in SSC(Separated Sector Cyclotron) power supply system. The result shows that we can preset data quickly and accurately.
