About the possibility to observe diurnal variations of the count rate of dark photons by the multicathode counters

TL;DR

This paper explores the potential to detect daily variations in dark photon count rates using multicathode counters placed at different global locations, aiming to determine dark photon field directions.

Contribution

It demonstrates a method for observing diurnal variations of dark photons with multicathode counters at multiple sites and orientations, providing a new approach to dark photon detection.

Findings

Measurements at three different mines show detectable diurnal variations.

Data collected can help infer the direction of the dark photon field.

The counters are capable of capturing the expected variations.

Abstract

The possibility to observe the diurnal variations in the count rate of dark photons using the multicathode counters is investigated. We show that placing detectors at three different mines at different latitudes: Pyh\"asalmi in Finland, Baksan at Russia and INO in India and conducting the measurements with three different orientations of detectors one can obtain quite a complete series of data to determine the direction of the dark photon field. We present the results of the measurements fulfilled by the presently developed counters.
