Abstract
This talk reports reactor flux and spectrum measurements with the Daya Bay full data set, 34% increase in statistics compared to the previous results.
Using detector data spanning effective $\mathrm{^{239}Pu}$ fission fractions $F_{239}$ from 0.25 to 0.35, Daya Bay measures an average IBD yield and a fuel-dependent variation in IBD yield, $d\sigma/dF_{239}$.
In addition, the yields and prompt spectra of the two dominant isotopes, $\mathrm{^{235}U}$ and $\mathrm{^{239}Pu}$, are extracted.
Using SVD unfolding techniques, the $\bar{\nu}_e$ spectra are estimated from the prompt spectra of $\mathrm{^{235}U}$, $\mathrm{^{239}Pu}$, and the total measurement, thereby providing a model-independent reactor $\bar{\nu}_e$ spectrum prediction for the other reactor $\bar{\nu}_e$ experiments.
