IAP Accelerator Based Microanalytical Facility for Material Science Studies V.E. Storizhko, V.I. Miroshnichenko, A. G. Ponomarev, and A.A. Drozdenko Institute of Applied Physics National Academy of Sciences of Ukraine, Sumy, Ukraine Corresponding Author: ponom@ipflab.sumy.ua Modern analytical facility developed at the Institute of Applied Physics (IAP) is based on a single-ended 2MV Van de Graaf accelerator. It consists of 4 beamlines to fulfill materials science tasks using following techniques: Rutherford backscattering, nuclear reaction analysis, ion luminescence and particle induced X-ray emission. Rutherford backscattering beamline is equipped with magnetic spectrometer with double focusing and resolution of 3 keV. A scanning nuclear microprobe is implemented in one of the beamline. Proton beam focusing is realized with two doublets of precision magnetic quadrupole lenses of a new design. Both doublets are made of single piece of the soft iron using electrical-discharge machining system. Resolution of 2 um with current about 100 pA is obtained. The microprobe is used for investigation of the impurity segregation to the grain boundary in the structural materials of the nuclear power systems. Article presents a description of the facility and its applications. |
