of exposure. In this way, the water molecule-cluster leaving the solution cathode could be observed and the mass of sputtered water could be studied as a function of discharge current and current density. In the case of a normal ELCAD, the mass of sputtered water was found to be about 150 mg/min with a current of 80 mA and a current density of 0.5 A/cm2. The mass of sputtered water decreased with decreasing current. A current-threshold of 20-40 mA was found. For the currents lower than this current-threshold, the sputtering stops, but the discharge, however, is henceforward operating. This refers to that the electrons can leave the solution still at such low current also. This is in accordance with the current threshold observed in the occurrence of the emitted atomic metal lines. In the case of capillary (abnormal) type of ELCAD, the mass of sputtered water was found to be 1500 mg/min with a current of 80 mA and a current density of 3.7 A/cm2. Using the same current and a copper cathode, the mass of sputtered copper is only 0.5 mg/min. The comparison of these data shows that the ELCAD operates in a self-generated saturated water vapor.
Imaging ellipsometer. — The first unit of our new type of multispectral imaging ellipsomters was successfully finished, tested, in cooperation with the Research Institute for Technical Physics and Materials Science HAS, and it is ready to be installed in the USA.
