We will discuss recent progress in making sub-keV nuclear recoil calibrations practical in a university lab environment. First, we will describe a 124SbBe (gamma,n) neutron source in which a novel Fe shielding method suppresses the outgoing gamma flux while allowing the unmoderated escape of the 24keV neutrons. Second, we will describe a method to moderate and then filter neutrons from a pulsed Deuterium-Tritium (DT) generator, enabling a pulsed keV-scale neutron source. And lastly, we will describe work towards large area neutron capture-based backing detectors required for a neutron scattering calibration of dark matter experiment targets.
