varying the oxygen flow rate into the system indicates that the main effect of substrate temperature during deposition is to change the oxygen concentration in the films, rather than directly introducing any temperature-dependent changes in the film properties. For films containing from 10-20 at. y0 oxygen, the Ta condensation coefficient and film growth rate are largely independent of temperature.

(USA) A rotary drum evaporator has proved itself capable of depositing thin films that are comparable if not superior to films deposited by other techniques. The thickness of the films is uniform and pinholes have been reduced to less than five per square inch. The model described is capable of handling 12 glass substrates of different sizes, but the design can easily be scaled up to accommodate even more.

33 651. A simple triggered vacuum gap. (India) A simple triggered vacuum gap has previously been described by the authors in this journal. Further studies have resulted in improvement of the performance with regard to sensitivity and consistency of the trigger characteristics and immunity from bridging due to metal particles eroded from the arc. The earlier design suffered from rather frequent bridging of the auxiliary gap and showed rather wide scatter in its trigger characteristics. In the present design thermally stable materials like fused quartz, machinable ceramic ‘Supramica 500 (Mycalex Corporation of America), lead titanate, barium titanate (LCC HTD) and silicon carbide have been used to insulate the trigger electrode from the cathode. Consistent triggerings free from bridging, at relatively low voltages of 200-400 V have been obtained. The materials used cover the range of permittivity E,.= 3.78-1850. It appears that higher permittivity materials result in lower triggering voltages. Silicon carbide gave by far the best performance in the improved design.
