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 the telecontrol of the UHVEM. In this paper, we would like to 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 the 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 us the availability of the current IPv6 networks and the new possibility of the future IPv6 networks. We will also describe our current telecontrol system and several future works.
