Defect Dynamics and Isomer Quenching in Th:CaF Crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +16
Thorium-229 doped calcium fluoride (Th:CaF) is a leading candidate for a solid-state nuclear clock, owing to the unusually low energy of the Th isomer transitio…
X-ray-induced quenching of the Th clock isomer in CaF
Ming Guan, Michael Bartokos, Kjeld Beeks +27
Thorium-229 has the lowest nuclear-excited state (an isomer state) at approximately 8.356 eV, making it excitable with tabletop vacuum-ultraviolet lasers. Despite the recent succes…
Optical Transmission Enhancement of Ionic Crystals via Superionic Fluoride Transfer: Growing VUV-Transparent Radioactive Crystals
Kjeld Beeks, Tomas Sikorsky, Fabian Schaden +11
The 8 eV first nuclear excited state in Th is a candidate for implementing an nuclear clock. Doping Th into ionic crystals such as CaF is expected to suppress n…
Growth and characterization of thorium-doped calcium fluoride single crystals
Kjeld Beeks, Tomas Sikorsky, Veronika Rosecker +13
We have grown Th:CaF and Th:CaF single crystals for investigations on the VUV laser-accessible first nuclear excited state of Th. To reach high dopi…
