Two laser-based diagnostics are used to determine the density (n e) and temperature (T e) of low-energy electrons confined in the negative glow of a dc helium glow discharge. Each diagnostic yields an independent relation between n e and T e. From the intersection of these relations we find n e= 5× 10 11 cm− 3 and k B T e= 0.12 eV for an abnormal cathode fall of 261 V in 3.50-Torr helium.
