Abstract：
In order to study new isotopes and nuclear decay properties in the A>170 mass region, the laser ion source is needed and developed. For on line isotope separator, it is required that the capillary ionization has a speciality of low hot ionization efficiency and high ion extraction efficiency. The principle of the hot capillary ionization was described. The employment of Nb capillary reduces the temperature for forming the plasma potential and inhibitory hot ionization. The ionization tube is made of a Nb capillary of 2.2mm outside diameter, 1.7mm inside diameter and 30mm effective length. The temperature is 1600-2500K when the current is 40-100A. The target chamber is structured by Ta tube of 0.1mm wall thickness and windows of 6μm Ta foil at two ends. Its maximum temperature is 2200K with the current 300A. The test experiment with on-line conditions at isotope separator ISOLAND has been performed.¹⁶⁷Yb(T_1/2=17.5min) isotope was produced in nuclear reaction ¹⁸O(50MeV/u)+^natTa→¹⁶⁷Yb. In the condition of target chamber temperature 2130K and capillary temperature 2130K, the total efficiency is 0.2%. This target ion source system will be satisfied in laser ion source.
