We have developed a data-acquisition (DAQ) system, whereby a CAMAC system is controlled using a graphical user interface (GUI) on a Windows NT(TM) system. This system has enabled easy DAQ operation with a sufficient data-acquisition performance, through the use of a CAMAC auxiliary crate controller. This system is now in practical use for measurements of (e, e'X) reactions at LNS. (C) 2000 Elsevier Science B.V. All rights reserved.
