We describe the progress in an experimental project aimed towards basic studies of electron trapping effects and efficiency enhancement schemes in free electron lasers. The experimental scheme is based on two TEA CO2 laser beams at different vibrational lines (wavelengths), a nonrelativistic (kV) electron beam and an accelerating field. The present minimum trapping efficiency detection capability of the system is 1-3%. The expected trapping under present conditions is close to this level, and will far surpass with further improvements.
