1. A radioisotope production gas target comprising a target chamber, a front adaptor, a rear adaptor, casings, a front flange, a rear flange and a metal sheet, wherein the target chamber is shaped of a hollow cylinder having an interior volume and has a plurality of inner fins protruding from an inner surface along a length of the target chamber;the front adaptor being shaped of a ring, a central part of which is bored, and which has a first circular groove on a radial outer side of the central part;the front adaptor having a target gas inlet communicating with the bored central part through a front surface of the front adaptor and feeding target gas to the interior volume of the target chamber, and a first coolant inlet communicating with the first circular groove through a rear surface of the front adaptor and feeding a coolant flowing along an outer surface of the target chamber, and the front adaptor being coupled to a front end of the target chamber such that the bored central part communicates with the interior volume of the target chamber with the first circular groove facing the target chamber;the rear adaptor that is coupled to a rear end of the target chamber, which includes a target gas outlet in an outer circumference thereof communicating with the interior volume of the target chamber and collecting the target gas after a nuclear reaction occurs, and which includes at least one slot in an inner circumference thereof at a portion where the rear adaptor is coupled with the target chamber;the casings being coupled between the front adaptor and the rear adaptor so as to enclose an outside of the groove of the front adaptor and an outside of the slot of the rear adaptor, the casings enclosing the target chamber and defining an annular space therebetween through which the coolant flowing along the outer surface of the target chamber flows;the front flange having a grid structure supporting the metal sheet and the front flange being coupled to the front surface of the front adaptor; andthe rear flange having a first coolant outlet discharging the coolant flowing along an outer surface of the target chamber and coupled to a rear surface of the rear adaptor,and wherein the metal sheet is disposed between the front adaptor and the front flange,and wherein the front flange includes a second groove formed around the grid structure, and a cover member covering a front of the second groove, and has a second coolant inlet in an outer circumference thereof. 2. The radioisotope production gas target as set forth in claim 1, wherein the target chamber comprises a plurality of conjoined target chamber units, each target chamber unit having at least one of the inner fins. 3. The radioisotope production gas target as set forth in claim 2, wherein the target chamber includes a welded joint between the target chamber units. 4. The radioisotope production gas target as set forth in claim 1, wherein the target chamber includes a plurality of outer fins protruding from the outer surface thereof along the length thereof. 5. The radioisotope production gas target as set forth in claim 1, wherein the target chamber includes a plurality of outer fins protruding from the outer surface thereof along the length thereof and comprises a plurality of conjoined target chamber units, each target chamber unit having at least one of the inner fins and at least one of the outer fins. 6. The radioisotope production gas target as set forth in claim 1, wherein the target chamber includes a plurality of outer fins protruding from the outer surface thereof along the length thereof and comprises a plurality of conjoined target chamber units, each target chamber unit having at least one of the inner fins and at least one of the outer fins, and the target chamber includes a welded joint between the target chamber units. 7. The radioisotope production gas target as set forth in claim 1, wherein the rear adaptor includes a concave space recessed from a portion where the rear adaptor is coupled to the rear end of the target chamber.
