A new Li beam emission spectroscopy (Li-BES) diagnostic system with a ~ cm spatial resolution, and withbeam energy ranging from 10 keV up to 120 keV and a 18 channel Avalanche photo diode (APD) detectorsystem sampled at 2 MHz has been recently installed and tested on the COMPASS tokamak. This diagnos-tic allows to reconstruct density profile based on directly measured light profiles, and to follow turbulentbehaviour of the edge plasma. The paper reports technical capabilities of this new system designed forfine spatio-temporal measurements of plasma electron density. Focusing on turbulence-induced fluctu-ation measurements, we demonstrate how physically relevant information can be extracted using theCOMPASS Li-BES system
