Estimation of Self-Ignited Plasma Density Using Plasma-Based Ion Implantation
Nobuyuki Fujimura, Kazuhiro Shimono, Hiromitsu Noguchi, Hiroshi Toyota, Yoshito Shirai, Takeshi Tanaka

Cite as:

Plasma density is estimated from the target voltage and current characteristics of the pulse modulator circuit in plasma-based ion implantation. The voltage recovery time constant directly reflects the ion sheath characteristics, ...  read more

Spore-Forming Bacteria Sterilization Using Plasma-Based Ion Implantation
Koji Kakugawa, Masatoshi Kubo, Hiromitsu Noguchi, Kazuhiro Shimono, Nobuyuki Fujimura, Yoshinobu Tsuchiya, Takeshi Tanaka

Cite as:

A main purpose of sterilization is to kill the harmful microorganisms. In food industry, the representatives of microorganisms which are difficult to sterilize are spore-forming bacteria. Because these bacteria are extremely ...  read more

Comparison of Plasma Spectral Characteristics Using a Plasma- Based Ion Implantation
Hiromitsu Noguchi, Nobuyuki Fujimura, Kazuhiro Shimono, Hiroshi Toyota, Yoshito Shirai and Takeshi Tanaka

Cite as:
