	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.

	Boron neutron capture therapy (BNCT) is one of the particle-beam therapies which use secondary products from a neutron capture on boron medicaments implanted into cancer cells. This has been originally studied with neutrons from nuclear reactors, meanwhile, many activities have been recently projected with accelerator-based neutron generation. In the iBNCT (Ibaraki BNCT) project, the accelerator is consisted with a radio frequency quadrupole (RFQ) and an Alvarez type drift-tube linac (DTL). Protons extracted from an ion source are accelerated up to 3 MeV and 8 MeV, respectively, and bombarded onto a beryllium target to generate neutrons. The design of the linac is based on the J-PARC one, but the most significant difference is the higher duty factor to have a sufficient epithermal neutron flux for BNCT. We have started the commissioning from the end of 2016, and the beam current of 1.3 mA with a repetition of 50 Hz has been achieved with an acceptable stability. Further beam commissioning and reinforcement of the vacuum and cooling water system will be performed toward higher beam current. In this contribution, the current status and future prospects of the linac will be presented.
