Andreas Leonhardt, Anna Hurhina, Marjolein Troost, Tina R. Pollmann

Solder flux residues photoluminesce in the visible range when exposed to VUV light relevant to liquid xenon detectors.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that all tested flux residues photoluminesce in the visible spectral region when exposed to VUV light.

C2weakest assumption

The commercial solder fluxes and residues tested are representative of those actually used during assembly of liquid xenon detectors and that the laboratory illumination conditions mimic the VUV scintillation light present in the detector.

C3one line summary

All tested resin-based solder flux residues photoluminesce in the visible spectral region when exposed to VUV light.
