  We analyzed the structure of the Thunderstorm Ground Enhancement using a
particle detector network on Aragats. We performed a statistical analysis of
the particle flux enhancement time series on a nanosecond time scale using the
largest TGE event on record, which occurred on May 23, 2023. Our findings
confirm that the TGE combines multiple Extensive Cloud Showers, or particle
microbursts, that arrive independently and provide stable particle flux on a
second time scale. The electron accelerator, operated by the dipole that
emerges in the lower part of the thundercloud, sends a large number of
electrons and gamma rays toward the Earths surface that sustains for minutes.
The experimental results are supported by simulations of electron
multiplication and acceleration in strong atmospheric electric fields.
