What are Electron Trains?
What do we know about them?
SE Rate vs. radial distance \(\Delta r\) between progenitor and child
Advancing the Liquid Bulk Hypothesis
Fits to power law at different drift time bands show exponent does not depend on drift time
Note: value for study conducted by Kopec et al. [5] was reported for 500 V/cm and “unchanged” for other fields
Thank you to our sponsors and 37 participating institutions!
Factor | Description |
---|---|
\(SE_{R} = S2_{phd} / n_{phd / SE}\) | “Raw” (extracted) S2 area in units of single electrons |
\(SE_{S} = SE_{R} / e_{eee}\) | “Surface” S2 area, i.e. \(SE_{R}\) corrected for extraction efficiency |
\(SE_{I} = SE_{S} \exp(t_{drift} / \tau_{e^-})\) | “Initial” S2 area, i.e. \(SE_{S}\) corrected for drift losses |
\(e_{loss} = SE_{I} - SE_{S}\) | Number of electrons lost while drifting |
\(\text{cm}^2\) | Area of liquid surface subtended by radial selection of pulses |
