A new-type windowless gas target has been developed to realize a dense target with a low gas flow rate. The target is similar to the conventional differentially pumped windowless gas target except that the target gas is blown into the target region from both the side holes of the beam entrance and exit. Due to the gas-confining action caused by the blown-in gas, the target thickness is about twice increased and the target density sharply falls in the holes. Most of the target gas is at rest and the density is uniform. The gas flow rate is the same as that of the conventional target and is about an order of magnitude lower than that of the dense gas-jet target.
