The radial correlation length L-r of electron density fluctuations has been measured using a two-channel O-mode reflectometer system in the helical-axis fusion plasma experimental device Heliotron J. The experimental results show that L-r is around 1.4 +/- 0.7 mm in three different magnetic field bumpiness configurations (i.e. low, medium and high) for the low-density electron cyclotron heating (ECH) discharges. In high-density neutral beam injection (NBI) discharges with HIGP and pellet injection, L-r is found to be around 1 +/- 0.2 mm.
