Correlation ECE (CECE) is a diagnostic technique that allows measurement of small amplitude electron temperature, Te, fluctuations through standard cross-correlation analysis methods. In Alcator C-Mod, a new CECE diagnostic has been installed[Sung RSI 2012], and interesting phenomena have been observed in various plasma conditions. We find that local Te fluctuations near the edge ([rho] ~ 0:8) decrease across the linearto- saturated ohmic confinement transition, with fluctuations decreasing with increasing plasma density[Sung NF 2013], which occurs simultaneously with rotation reversals[Rice NF 2011]. Te fluctuations are also reduced across core rotation reversals with an increase of plasma density in RF heated L-mode plasmas, which implies that the same physics related to the reduction of Te fluctuations may be applied to both ohmic and RF heated L-mode plasmas. In I-mode plasmas, we observe the reduction of core Te fluctuations, which indicates changes of turbulence occur not only in the pedestal region but also in the core across the L/I transition[White NF 2014]. The present CECE diagnostic system in C-Mod and these experimental results are described in this paper.

In this proceedings, physicists from all over the world discussed the state-of-the-art in the field of Electron Cyclotron Emission (ECE) and Electron Cyclotron Resonance Heating (ECRH) in great detail. Papers have been presented in the field of millimeter wave technology for ECE and ECRH, theory of propagation and absorption of EC waves in plasmas, EC current drive theory and experiments, nonlinear effects, ECRH sources, transmission line technology, experiments and plans. Comprehensive summaries on the main topics of the EC-10 workshop (theory, diagnostics, experiments, techniques) have been written by world renowned experts. The proceedings is indispensable for anyone who is working in the field of ECE and ECRH.

The conference proceedings will include the papers of approximately 50 key specialists from most of the world's major fusion laboratories, including the European Community, the U.S., Russia and the PRC. The unifying themes are the emission of electron cyclotron waves by high temperature plasmas and the reciprocal process, absorption, which can be used for heating, non inductive current drive and diagnostic purposes.
