X-ray-induced quenching of the $^{229}$ Th clock isomer in CaF $_{2}$

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 $^{229}$ Th is a candidate for implementing an nuclear clock. Doping $^{229}$ Th into ionic crystals such as CaF $_{2}$ 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 $^{232}$ Th:CaF $_{2}$ and $^{229}$ Th:CaF $_{2}$ single crystals for investigations on the VUV laser-accessible first nuclear excited state of $^{229}$ Th. To reach high dopi…
