Biography

Research Interests

Daniel McCartt works at LLNL’s Center for Accelerator Mass Spectrometry (CAMS) developing laser-based spectroscopic methods. CAMS leverages AMS’s ability to detect rare isotopic species to perform incredible science. He is currently developing a cavity ring-down spectroscopy (CRDS) instrument for the detection of carbon-14. The measurement of carbon-14 with accelerator mass spectrometer is often cost prohibitive due to the substantial investment required in both facilities and technically proficient staff. A more affordable carbon-14 CRDS would enable the proliferation of powerful carbon-14 scientific applications such as micro-dose drug testing and anthropogenic carbon cycle monitoring. The current prototype is capable of sub-contemporary carbon-14 measurements and is suitable for use in biological studies.
