Major Modification/Development history
(1991-1998) A 15 poloidal-channel array system was originally installed at P17.
(1999 winter) It was moved to P5, and number of detector for the poloidal array was increased to 23 channels.
(2005 Spring) Data acquisition system for SLOW sampling (CAMAC LeCroy8512+FUJITSU ISP) was replaced to New network acquisition system(CAMAC Kinetic System 4008+Toyo Tech. CCnet+SUN Blade150):
memory size for each channel was increased from 16k to 128k, and acquisition speed was enhanced extremely.
(2005 Summer) Data acquisition system for FAST sampling (CAMAC KS4020+CES SVUC7213+SUN SPARC20) was replaced to New network acquisition system(CAMAC KS4020+Toyo Tech. CCnet+SUN Blade150):
data size for each channel was increased from 256k to 512k, and acquisition speed was enhanced extremely.
