 We started to exhibit the total collection data in GAMAM10 on Plasma Research Center, University of Tsukuba with the collaboration of LABCOM group since 2008.  In GAMMA 10, base data acquisition is performed by using a CAMAC system by using Windows PC.  These data is collected on the Soralis10 data server system with 4TB RAID system.  In addition, we have many stand alone PC data collection systems for many diagnostics.  We constructed the Linux (CentOS) data collection server system with 24TB RAID, in order to collect total collection data in GAMMA 10, such as CAMAC collection data and many other diagnostic data.  We have connected the NIFS LABCOM/X system under the new framework of “Fusion Virtual Laboratory” where users can access the data equivalently regardless of their whereabouts.  Such the activity is named “SNET”, which is based on a closed VPN on Japanese academic internet backbone SINET3 and covers multiple experimental remote devises.   In 2010, we started Thomson scattering measurement for electron temperature measurement and microwave reflectmeter for density fluctuation analysis.  Moreover, we added the middle speed camera for plasma image analysis.  We send the GAMMA 10 total collection data from the GAMMA 10 data collection server to the NIFS LABCOM/X system, and succeeded.  In tabel 1, we show the total transfer data names and sizes.  Total file size of transfer data is about 1.2 TB/year.   The essential information of experiment operation, the sequence timings and the shot number, are given by the GAMMA10 experiment control system through the hard wires and the http network communication, respectively.  In addition to share the already acquired data, a remote DAQ node was installed at GAMMA10 to measure eight channels of microwave interferometer signals in the central cell plasma.  Fig. 1.
