We have already proposed a bilateral control scheme with energy balance monitoring under time-varying communication delay. In this paper, experimental results using the proposed control scheme over the computer network are shown. In the previous work, we dealt with a situation when the communication is in breakdown. However, we did not discuss how to recover the system after the communication line comes back. In this paper, we also propose a way to recover the system from the communication blackout. Experimental results show the validity of the proposed methods.

Angular and charge-state distributions are measured for 5-15-keV. Ar 0 and Ar + ions reflected from a KCl(001) surface under glazing angle incidence. The ionization of Ar 0 is almost completely suppressed at incident angles smaller than a critical angle (11-22 mrad, depending on the ion energy), while a considerable fraction of incident Ar + ions are neutralized. It is demonstrated that a position-dependent Auger neutralization rate can be derived from the observed result without any assumption except for the surface continuum potential. The obtained Auger neutralization rate shows a simple exponential dependence as is usually assumed.
