The Scintillating Fiber Detector (SFD) on the EQUATOR-S is based on the light
emission property of some materials when hit by ionising radiation. Optical
fibers guide the emitted light to a photodiode operated in current mode. A
logarithmic amplifier converts this detector current to an analog output
voltage. Energy discrimination is achieved by using three differently shielded
channels. This way electrons above 0.26, 0.4, and 1.9 MeV are measured, and
protons above 6.3, 9.5, and 35 MeV, with a time resolution of 64 s. A constant
current is added periodically to calibrate the system.
