These particles offer the possibility for extra diagnostics for detailed investigations into the cooling process at the very low energy of the ELENA ring. To this effect a monitor was installed downstream of the electron cooler to measure the recombination of protons with the cooling electrons. Although protons have never been used in ELENA, H⁻ ions are routinely used to setup and optimise the ring. The installed device is now used to monitor the stripping of the H⁻ ions on the residual gas and in the presence of electrons generated by the cooler, providing some insight on the evolution of the beam size during the deceleration cycle and the performance of the electron cooler on the two cooling plateaus.
