Abstract
Abstract
The PADME experiment at LNF-INFN employs positron-on-target-annihilation
to search for new light particles. Crucial parts of the experiment are the charged
particle detectors, composed of plastic scintillator bars with light transmitted
by wavelength shifting fibers to silicon photomultipliers (SiPMs). The location of
the detector — close to a turbomolecular pump, inside a vacuum tank, and exposed
to 0.5 T magnetic field — has driven the design of custom modular SiPM front-end
and power supply electronics. The design of the system and its performance, confirming
the desired sub-ns resolution on the reconstructed particle flying times, is shown
and discussed.
