provides values of the plasma line integral density in scenarios with average densities ranging from a few times 10<sup>18</sup> m<sup>–3</sup> to more than 5&times;10<sup>19</sup> m<sup>–3</sup>. The results have been compared with those from the 2 mm (microwave) interferometer, obtaining an excellent agreement. Working with a final bandwidth of 4 kHz, a one pass line integral error level about &plusmn;2&times;10<sup>17</sup> m<sup>–2</sup> has been achieved.
