  • Abstract: A Low Energy Detector (LED) for the measurements of energy spectra and composition of solar particles in the energy range 1-15 MeV/n has been designed, built and tested. The sensor consists of three layers of circular silicon detectors. The first detector layer is composed of seven separate small and thin detectors. With the desing, a low energy threshold and relatively large geometric factor was reached. The nuclei and their isotopes are identified by measuring the energy losses in the first two detector layers. The third layer is used as an anticoincidence shield. The performance of the sensor has been tested in two accelerator runs.
