Outline Activities
We are originally developing an equipment for observing Coulomb crystal and liquid in a DC glow discharge. Using this equipment, the following phenomena have newly been observed. (i) The levitated microparticles are clearly separated in a few layers (or phases): the lower layer is crystal-like and sparse, the middle layer is relatively dense and the included particles are slowly moving, and the upper layer consists of very fast-moving microparticles. (ii) There are three trap areas in this equipment. The flow of microparticles between the center and side areas has been observed. It is possible to control the flow direction by suitably adjusting the applied voltage to the electrodes. In addition, we are going with molecular dynamics calculations to reproducing the experimental results.

I am in charge of a few class of KIKAN education for undergraduate students, and developing news classes for active learning.

Academic Activities
1. Kenji Furuya, Akihiro Ide, Akira Harata, Mass spectrometric investigation of high-mass neutral species in the downstream region of Ar/CH4 plasmas, Journal of Applied Physics, 10.1063/1.3605543, 110, 1, 013304, 2011.07, Mass analysis was carried out on neutral species in the downstream region of Ar/CH4 plasmas. The ionization of the neutral species by Li+ attachment, which can inhibit the fragmentation accompanied by ionization in most cases, successfully led to the observation of high-mass neutral hydrocarbons containing up to twenty-seven carbon atoms. Pure Ar and Ar/H2 plasmas were also used to investigate the influence of sputtering of an amorphous hydrocarbon (a-C:H) film deposited during the generation of the Ar/CH4 plasmas. In addition, time dependence of intensity in several neutral species accompanied by the growth of the a-C:H film and its CH4 partial pressure dependence were observed for the first time. On the basis of the present experimental results, the desorption of high-mass neutral molecules from the film to the gas phase is concluded..
