It was found that films properties are influenced mainly by pulse volume energy density and, in less extent, by average surface power density of discharge, with optimum at about 75 J/cm/sup 3/ and 2-3 W/cm/sup 2/ correspondingly. Diamond-like films deposited from methane under these conditions are similar to those obtained by traditional low-pressure (p<10 Torr) methods of chemical vapour deposition, but the equipment for a-C:H film deposition in the surface discharges is much simpler and cheaper than the vacuum systems with various types of plasma generator conventionally used for this purpose.

The installation can be used for cleaning hazardous off-gases of-power plants and industrial objects, as well as in some exotic fields of application such as destruction of the chemical weapon stocks. Comparative data on the operation of the two types of gas-discharge switches-thyratron with heated cathode and thyratron with cold cathode (pseudo-spark switchboard-PSS) with a rated voltage of 50 kV are also reported. Operating time attained for the PSS of Russian design and fabrication in testing modes of operation, allows to expect a service life in real modes of operation up to 3-7 thousand hours.","PeriodicalId":410823,"journal":{"name":"12th International Conference on High-Power Particle Beams.

In the experiment, microcontroller IC Z86 (Zilog) and 87C196KR (Intel) chips, were used. The repetitive pulsed electron accelerator URT-0.5 was used as an X-ray generator. It produced 7.6 Gy per minute (50 pps) at 5 cm from the anode on the axis, where the chips were placed. The maximum dose rate was 6.36 kGy/sec. The absorbed dose was measured using LiF-detectors. Tested chips with special program in their memory were irradiated until the information had been erased. A periodic control of the chip memory during the irradiation was performed. It has been found experimentally that CMOS PROM become free after irradiation with a dose of about 380 Gy, if it was wrapped up with 10-/spl mu/m thick Al foil. The foil only connected chip pins. It is possible to make this erasure procedure with the same chip more than twice.
