  Today providing enough supplies of 99mTc / 99Mo as a high usage radioisotope in diagnostic nuclear medicine for the world demand is a big challenge. One of the proofed ways to access reliable source of this radioisotopes is production using e-LINAC [1]. In this investigation it was tried to find the simple and the optimized design of 99Mo production target based on photoneutron reaction using e-LINAC. Based on the Monte-Carlo calculation for radiation transport and finite element thermal analysis, 9 thin plates of enriched 100Mo was suggested. Equal distance between plates was considered for cooling to prevent target melting. The main target includes only 100Mo in one-stage approach method to increase production rate in compare with two-stage approach [2]. Applying 2.5 m/s for inlet velocity of cooling water provides suitable cooling process with maximum temperature of target about 900 ˚C.
