Abstract: We study some of the physics potential of an intense $1\,\mathrm{MCi}$$^{51}\mathrm{Cr}$ source combined with the {\sc Majorana Demonstrator}enriched germanium detector array. The {\sc Demonstrator} will consist ofdetectors with ultra-low radioactive backgrounds and extremely low energythresholds of~$\sim 400\,\mathrm{eV}$. We show that it can improve the currentlimit on the neutrino magnetic dipole moment. We briefly discuss physicsapplications of the charged-current reaction of the $^{51}\mathrm{Cr} neutrinowith the $^{73}\mathrm{Ge} isotope. Finally, we argue that the rate from arealistic, intense tritium source is below the detectable limit of even atonne-scale HPGe experiment
