An experimental investigation on the interaction between ultra-short intense laser pulses and microcapillary has been carried out. The X spectrum from glass microcapillary is obtained successfully. Experimental results show that the X-ray radiation enhanced intensively with increasing the capillary length. In the same condition, the X-ray radiation yields of capillary target are more than one order higher than that of plane one. The average electron temperature of capillary plasma is higher when the laser pulse energy is increased.
