[en] The feasibility of PIXE (Proton Induced X-Ray Emission) radiation as an intense source of K, L, and M-shell x-rays is explored using PBFA-II as 2-40 MeV, multi-MA proton source. Because the peak of the characteristic x-ray production cross sections lie in the multi-MeV range for protons, PBFA-II, when optimized for maximum proton current, should be an ideal source. However, the efficiency for converting the proton energy to characteristic x-ray energy in the target is only of the order of 0.1 and is strongly dependent on target material. Furthermore, the emission of these low-energy x-rays from the target is dominated by absorption in the target. Two simple target designs have been considered that enables about 20 of the x-rays generated in the target to reach an area outside the target that is to be irradiated. One design which employs high magnetic-fields suffers from complications arising from the fields; the other design employs a tilted target and suffers from proton contamination at the area to be irradiated. Owing to the high efficiency possible with the tilted target, it is discussed in detail. Depending on the proton energy and the target material, surface doses up to a few hundred cal/gm over 500 cm² are possible using PBFA-II. Because of the low energy of the x-rays, however, the fluence is only of the order of 0.2 cal/cm² for all the targets considered. Additionally, because of the high energy density of the beam on target, a shield that is sufficiently thick to stop the target debris will most probably be too thick to transmit the low-energy x-rays. Accordingly, it will be necessary to do without such a shield and to complete x-ray effects measurements before the slow velocity debris arrives. 18 references, 30 figures, 11 tables
