Spiral Structures in ECR Plasmas

(some jpeg pictures for Dr. M.Tanaka ...)

These pictures show funny structures (often appear as SPIRAL)
in 2.45GHz ECR plasmas (this time introduced gas is Hydrogen).

These are taken by still camera, and are mainly tested(junk).
Number in filenames coresspond exposure time.

These are captured from video.
Hydrogen Pressure is about <1e-3 Torr (except ECR11454.JPG).

All pictures abobe are taken by S.Sato at Nippon Institute of Technology.

Sorry, Parameters are still explored in my desk.
