To fully characterise different CNT arrays (conditioning process, emitted current, lifetime) and to investigate the optimum electrical configuration of the source to be used in an electron gun, a cold cathode test bench (CCTB) has been set up. From the measurements performed on the CCTB, an electron gun has been designed, constructed and is being tested to measure the properties of an electron gun using a larger (4cm diameter) CNT array as the source. The CCTB has been modified to incorporate a beam transport system as well as the relevant diagnostics needed to perform the experiments. The results will be compared to the CST Particle Studio simulations and will be used to optimise the design for use in the ELENA low energy electron cooler.
