1 Introduction to UniDAQ Makoto Yoshida (Osaka Univ.) MICE DAQ 2005/9/1

2 UniDAQ Unix-based DAQ system Unix-based DAQ system developed by KEK, TIT, U. Michigan, U. Minnesota in 1990s developed by KEK, TIT, U. Michigan, U. Minnesota in 1990s initiated for SSC project initiated for SSC project A lot of experience at KEK A lot of experience at KEK well documented, experts in Osaka-U and KEK well documented, experts in Osaka-U and KEK references references (Genaral) (Genaral) (for Linux) (for Linux)
