Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Jeongseog Song Project Name: Prod_medi_isotopes Division: PHY and NE Project title: Medical Isotopes production at ANL Associated funding: DOE`s office of Science Other Systems: Science: We are going to produce medical isotopes such as 47Sc, 67Cu, 225Ac etc, via photo-nuclear reaction using Low Energy Accelerator Facility(LEAF) at ANL for medical application. Electron beam irradiates to the convertor(Ta or Al) then generate gamma ray by Bremsstrahlung. Resonance energy of gamma ray for photo-nuclear reaction is at 15 MeV, so electron energy should be ~ 40MeV. Reactions for producing medical isotopes are as follows. - 48Ti(gamma,p)47Sc - 68Zn(gamma,p)67Cu - 226Ra(gamma,p)225Ac Project description: In order to design the medical isotopes production target, we need to use PHITS(Particle and Heavy Ion Transport code System) which can simulate heat deposit on the convertor and target and yield of wanted isotopes. PHITS is basically Monte Carlo simulation code for particle tracking and its production and to run batch job is efficient. We will develop production target based on simulation results. In order to install, compile and run batch job PHITS require fortran compiler(mpi90 or ifort), MPI, etc,. Since photo-nuclear cross section(gamma,p)for medical isotopes production is very low, no. of particles should be at least 1E+7 and ~100 batch jobs at once will be need. For examples, in case of C3TA design convertor thickness should be optimized to be able to sustain very large power deposit and gamma,p yield we are interested in is around 1e-8/source and convertor thickness is variable up to 6mm. To design target for each isotopes 30 of number of run is required.
