abstract = {A desired temporal accuracy of scintillator-based detectors
is less than 100 ps. In medical imaging, this is necessary
for successful time-of-flight positron emission tomography
(TOF-PET) measurements. In high-energy physics, the
calorimeter time resolution must also be on the order of
tens of picoseconds. In this work we describe a way to
achieve such a high level of performance for a detector
consisting of a monolithic scintillator that distributes
light over several cells of an analog silicon
photomultiplier (SiPM) array. Each of the cells is read and
analyzed separately, applying a waveform sampling
(WFS)technique combined with a nonlinear rise approximation
(nLRA).Initially, due to a specific spatiotemporal
distribution of photons in the scintillator as well as
saturation and recovery effects inherent to SiPMs, the
spread of arrival times deduced from signals of different
cells can exceed 1 ns for the same array and the same event.
To improve the timing performance we propose a method of
equalization of arrival times for predominantly illuminated
cells in the same SiPM array. This results in a coincidence
time resolution (CTR) below 100 ps FWHM for a pair of
identical detectors},
