Telecontrol of ultra-high voltage electron microscope over global IPv6 network

Osaka University has an ultra-high voltage electron microscope (UHVEM) which can provide high quality specimen images for worldwide researchers. For usability improvements, we have worked on telecontrol of the UHVEM. We introduce a part of our activities on the telecontrol of the UHVEM. In order to remotely control the microscope, we must provide high quality dynamic images of the specimen with low latency to the remote site. We have used DVTS for image transfer. In iGrid2002, we transported DV streams over global IPv6 networks from the UHVEM in Osaka, Japan, to the National Center for Microscopy and Imaging Research in San Diego and iGrid2002 conference venue in Amsterdam, Holland. This experiment shows the availability of current IPv6 networks and the new possibility of future IPv6 networks. We also describe our current telecontrol system and future work.
