	The beam commissioning of the linac for the boron neutron capture therapy of Ibaraki prefecture (i-BNCT) has been started. The accelerator of i-BNCT consists of the 3-MeV RFQ and 8-MeV DTL. The design of RF structure of them is based on the J-PARC linac. After the first demonstration of neutron production on December 2015, significant modifications to the linac were given in order to increase the operation stability and the beam power. The progress of the beam commissioning of the i-BNCT will be presented.

	The Superconducting rf Test Facility (STF) at High Energy Accelerator Research Organization (KEK) was built for research and development of the International Linear Collider (ILC). In order to satisfy the stability requirement of the accelerating field, a digital low-level RF (LLRF) control system is employed. In this control system, signal from a cavity is down-converted into intermediate frequency (IF) signal before being digitized by analog-to-digital converter (ADC). In order to reduce the required number of ADCs, we proposed a technique that combines several IFs and to be read by a single ADC. Signal reconstruction of each IF is performed by digital signal processing. The performance of this technique, which is named IF-mixture, is reported in this paper.
