A re-analysis of x-ray heated aluminum scattering data

TL;DR

This paper re-analyzes x-ray scattering data on aluminum, revealing that previous temperature measurements may be unreliable due to overlooked uncertainties and experimental conditions, leading to discrepancies with theoretical models.

Contribution

It highlights the importance of including uncertainties and accurate experimental conditions in data analysis, challenging previous temperature claims.

Findings

Original analysis lacked uncertainty considerations.

Re-analysis shows poor agreement with models.

Heating likely lower than previously claimed.

Abstract

A re-anaylsis of the x-ray scattering data in Sperling et al. indicates that the measurement of elevated temperatures may be unreliable. The original analysis did not include uncertainties in the instrument function used to extract the plasmon signal. Including these effects leads to poor agreement with the theoretical models. The experimental conditions were also not measured and the heating was likely significantly lower than claimed.
