abstract = {Light sources emitting short pulses are needed in many particle physics experiments using
optical sensors as they can replicate the light produced by the particles being detected and are also an
important calibration and test element. This work presents NOPELED, a light source based on LEDs
emitting short optical pulses with typical rise times of less than 3 ns and FullWidth at Half Maximum
lower than 7 ns. The emission wavelength depends on the model of LED used. Several LED models
have been characterized in the range from 405 to 532 nm, although NOPELED can work with LED
emitting wavelengths outside of that region. While the wavelength is fixed for a given LED model,
the intensity and the frequency of the optical pulse can be controlled. NOPELED, which also has
low cost and simple operation, can be operated remotely, making it appropriate for either different
physics experiments needing in-place light sources such as astrophysical neutrino detectors using
photo-multipliers or positron emission tomography devices using scintillation counters, or, beyond
physics, applications needing short pulses of light such as protein fluorescence or chemodetection of
heavy metals.},
