Charge Exchange Spectroscopy is a key diagnostic on the Joint European Torus for radial profiles of ion temperature, toroidal rotation, and impurity densities. This paper describes the current status and the improvements made over the last 5 years. The current system consists of 2 periscopes looking at one of the 2 banks of neutral heating beams, 90 optical fibres defining viewing directions, and 7 spectrometers with CCD cameras. The upgrade has involved: replacement of the 2 periscopes and windows; a doubling of the number of optical fibres (plasma viewing directions); new cameras for the existing spectrometers, improvements to the throughput and long-term stability of the 5 existing spectrometers; and the addition of 2 new high-throughput spectrometers with their CCD cameras from ORNL. This work has culminated in improved spatial resolution, increased sensitivity of all the plasma viewing channels (for some by a factor ~3 or more), and enhanced time resolution from 50ms to around 10ms.
