	CTF3 is a Test Facility focusing on beam-based studies of the key concepts of the Compact Linear Collider CLIC. Over the past several years many aspects the CLIC two-beam acceleration scheme were studied in CTF3, including the crucial issue of drive beam stability. The main sources of drifts and instabilities have been identified and mitigated, helping to improve the machine performance and showing significant progress towards the experimental demonstration of the very stringent requirements on current, energy and phase stability needed in CLIC. In this paper, the more effective techniques and feed-backs are summarized. The latest measurements on beam stability are reported and their relevance to CLIC is discussed.

	The RF system of CYCIAE-14 consists of a set of 20kW amplifier, two 1/4λ RF cavities connected in central region, the transmission line and a set of LLRF system. The LLRF system, based on DDS and DSP, has achieved the close-loop adjustment of accelerating voltage and the resonant frequency. The RF system design for CYCIAE-14 was started in 2010, and the fabrication of the major equipments was finished in 2011. The installation and commissioning was completed in early 2012, satisfying the design requirements. This article describes the design of the RF system, and summarizes the difficulties encountered in the process of manufacture, installation and commissioning. Some of the problems caused by the transmission line and the RF leakage are analyzed, followed by the measures taken to solve these problems.
