Paper Abstract

We have upgraded the data acquisition system for the instruments of Subaru Telescope in these three years. We report the performance of the new data acquisition system Messia5, and the performance of the instruments whose acquisition system have been upgraded to the new system. The most important purpose of the replacement is increasing the observation efficiency. The second purpose is reducing the time and the effort to maintain the data acquisition system. The third purpose is to lead developments of next generation instruments. The new data acquisition system Messia5 is constructed with a commercial DSP board and works with Linux operating system. It has the performance to handle 160MByte/s continuously. It does not only have a capability to be applied to optical instruments, but also has a potential to be applied to infrared instruments. We have successfully upgraded the data acquisition system of the three optical instruments of Subaru Telescope, which are Suprime-Cam, FOCAS, and HDS. We have also upgraded that of an infrared instrument SIRIUS which has three HgCdTe 1k x 1k infrared arrays in April 2004.
