abstract = {The event-driven hybrid-pixel detector readout chip,
Timepix3, has the ability to simultaneously measure the time
of an event on the nanosecond timescale and the energy
deposited in the sensor. However, the behaviour of the
system when two events are recorded in quick succession of
each other on the same pixel was not studied in detail
previously. We present experimental measurements, circuit
simulations, and an empirical model for the impact of a
preceding event on this energy measurements, which can
result in a loss as high as 70 $\%.$ Accounting for this
effect enables more precise compensation, particularly for
phenomena like timewalk. This results in significant
improvements in time resolution -- in the best case,
multiple tens of nanoseconds -- when two events happen in
rapid succession.},
