Towards Special Daemon-Sensitive Electron Multiplier: Positive Outcome of March 2009 Experiment

TL;DR

This paper reports experimental evidence supporting the existence of daemons, hypothetical particles, with increased confidence levels, and explores the effectiveness of special electron multiplier tubes in detecting them.

Contribution

It presents new experimental data using daemon-sensitive detectors that increase confidence in daemon flux detection and suggests the potential of dark electron multiplier tubes for daemon detection.

Findings

Daemon flux confidence level raised to ~5Sigma

Detected diurnal modulation of daemon flux

Estimated daemon flux lower limit as ~3.4x10^-7 cm^-2s^-1

Abstract

Results of the experiments on daemon detection performed in St-Petersburg in March 2009 are presented. Adding the data obtained with the daemon-sensitive FEU-167-1 PM tubes to the data amassed in our previous measurements (starting from 2000) raises the confidence level of existence of the spring maximum in NEACHO (near-Earth almost circular heliocentric orbit) daemon flux to ~5Sigma. The first test experiments conducted with the "dark" electron multiplier tubes, - TEU-167 with a thick (~0.5 um) Al coating over all of the inner surface of the near-cathode multiplier section, including also its front screen, look encouraging. They provide supportive evidence for the existence of diurnal modulation of the daemon flux and offer ~3.4x10-7 cm-2s-1 for its lower limit in March, in good agreement with our earlier estimates and measurements.
