	For the commissioning of the Myrrha proton Linac an Emittance Meter Instrument (EMI) has been foreseen. The EMI will be installed in a dedicated test bench for linac commissioning. The test bench will be initially placed after the RFQ with energies of 1.5 MeV, and in later stages moved to other sections of the Normal Con-ducting Linac for operation at 6 and 17 MeV. The Myrrha EMI will be composed by two slit and grid subsystems for measurement of the phase space in the horizontal and vertical directions. For collimating the beam, graphite slits are used, and the beam aperture is measured in the SEM grids placed downstream. Then, the control system performs signal amplification, data acquisition, and motion control, with the different sys-tems integrated in an EPICs IOC. The system, manufactured by ESS-Bilbao and Proac-tive R&D, has been tested on the ESS-Bilbao 45 keV and soon will be integrated in Myrrha facilities. We present the EMI design, with irradiation analysis and emittance reconstruction, and the integration tests results.

THPOPA18	Development of a Tuner Control System for Low-Energy Superconducting Linac at RAON	controls, cavity, LLRF, cryomodule	778
	H. Kim, M.O. Hyun, H. Jang, M.S. Kim, Y. Kim IBS, Daejeon, Republic of Korea
	Funding: This research was supported by the RISP of ibs funded by the Ministry of Science and the National Research Foundation (NRF) of the Republic of Korea under Contract 2013M7A1A1075764. We propose a tuner control system for low-energy superconducting linac at RAON. The frequency error of the superconducting cavities must be smaller than a few of Hz to operate in beam acceleration mode. To minimize the freuqency error as much as possible, the error is calculated in the low-level RF(LLRF), and the proposed tuner control system changes the superconducting cavity frequency by using a mechanical tuner and a motor attached to the cavity directly. This control system deals with not only the initial frequency error of the cavity but also the frequency drift of the cavity induced by external disturbance such as the slow fluctuation helium pressure automatically. In addition, an automatic proportional gain calibration technique is also proposed. In this paper, the detailed operation and techniques will be described.
