	Y.G. Song, S.Y. Cho, J.H. Kim KOMAC, KAERI, Gyeongju, Republic of Korea
	The KOMAC facility consists of low-energy component, including a 50-keV ion source, a low energy beam transport (LEBT), a 3-MeV radio-frequency quadrupole (RFQ), and a 20-MeV drift tube linac (DTL), as well as high-energy components, including seven DTL tanks for the 100-MeV proton beam. The KOMAC has been operating 20-MeV and 100-MeV proton beam lines to provide proton beams for various applications. Approximately 20 stripline beam position monitors (BPMs) have been installed in KOMAC linac and beamlines. A data-acquisition (DAQ) system has been developed with various platforms in order to monitor beam position signals from linac and beamlines. This paper describes the hardware and software system and test results.

	S.Y. Cho, J.J. Dang, J.H. Kim, Y.G. Song KOMAC, KAERI, Gyeongju, Republic of Korea
	The Korea Multi-purpose Accelerator Complex (KOMAC) proton accelerator consists of 11 Drift Tube Linac (DTL) tanks, and each tank’s RF phase setting must be matched to increase synchronous acceleration of continuous tanks. A series of processes operate on the basis of JAVA and MatLAB languages, and the phase scanning program and the analytical program are classified and used independently. To integrate the two programs, the new integrated program of the RF scan application is developed based on python and epics scan module for the stability with some upgrade functions.
