Times Cited Count:5 Percentile:38.5(Physics, Applied)Using a semiconductor microwave source and a coaxial cable for microwave transmission, a compact microwave-assisted, laser-induced breakdown spectroscopy system without a microwave cavity or waveguide was developed. Several types of electrode heads were tested, so that the emission intensity was 50 times larger than without microwave. The limit of the enhancement effect was also found.

A 972MHz circlator is currently developed. In the high-power test of the prototype,rf breakdown was observed at the matching post. Rf characterristics obtained by simulations and low-power tests will be presented.

Times Cited Count:21 Percentile:79.04(Nuclear Science & Technology)High power radiation experiments of a remote steering launcher for an EC H&CD system were carried out to study the characteristic of the rf beam steering and transmission. The remote steering launcher consists of a 4.632m corrugated square waveguide (45.7 45.7mm
) and a movable flat mirror which is placed at the input of the waveguide. Measurements were made in the range 0-10
at a frequency of 170GHz. The measured radiation pattern is clearly a Gaussian-like distribution, which is in agreement with the low power measurements. A steering capability of up to 10
was experimentally confirmed. Transmission and radiation of 0.5 MW-3.0 sec and 0.2 MW-10.0 sec pulses were successfully demonstrated over a steering angle range of 0-10
. No arcing was observed during the experiments and no damage to the waveguide was found after the experiments were finished. We confirmed that remote steering was a possibly alternative scheme of rf beam steering for EC H&CD.
