Contribution

The study provides the first measurements of isothermal compressibilities of linear alkylbenzene, crucial for neutrino detector applications.

Findings

Densities measured at three temperatures and pressures up to 10 MPa.

Calculated isobaric thermal expansion coefficients.

First reported isothermal compressibilities of linear alkylbenzene.

Abstract

We report the measurements of the densities of linear alkylbenzene at three temperatures over 4 to 23 Celsius degree with pressures up to 10 MPa. The measurements have been analysed to yield the isobaric thermal expansion coefficients and, so far for the first time, isothermal compressibilities of linear alkylbenzene. Relevance of results for current generation (i.e. Daya Bay) and next generation (i.e. JUNO) large liquid scintillator neutrino detectors are discussed.
