Solubility of D in Be

$$ K_\mathrm{s} = K_\mathrm{s0}\exp \left(-\frac{E_\mathrm{s}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]

Comment

TDS measurements followed by TMAP modelling with different values for D and S until spectrum matched approximately. Data provided by M. Lavrentiev (UKAEA, 2024) with permission from STEP.
