“…Experimental results on electron energy deposits in thin silicon layers are reported in Meroli et al (2011), Dourki et al (2017. Table 5 summarizes the simulation results for deposited energy and minimum number of detectable electrons per second incident perpendicularly on the H-SPACE sensor surface.…”

The fleet of present and future space missions aimed at studying the Sun and the solar-terrestrial relationships carryparticle detectors, among other instruments. The monitoring of intense solar activity and solar energetic particle (SEP)events provide fundamental contributions to Space Weather and Space Weather science. Unfortunately, very few of these instruments are optimizedfor the  measurement of the proton differential flux above 200 MeV/n. We show that by increasing this minimum energy to 400-600 MeV/n it is possible to infer the trend of the differential flux with small uncertainties up to GeV energies, while this is not the case if the measurements are limited  to 200 MeV/n. To this purpose, we report on the characteristics of a single instrument meant for the detection of  solar flares and high-energy particles, galactic magnetar activity and gamma-ray burst observations. The instrument is based on hydrogenated amorphous silicon as a sensitive material that presents an excellent radiation hardness and finds application for particle beam characterization and medical purposes.

“…The evaluation of the electron flux detection limits is based on FLUKA [45][46][47] simulations of the same 4x4x0.0082 mm 3 device crosschecked with experimental results of electrons crossing thin silicon layers [48,49]. Extending the sensor area to 20x20 mm 2 and using the whole spectral range of Fig.…”

The characteristics of a hydrogenated amorphous silicon (a-Si:H) detector are presented here for monitoring in space solar flares and the evolution of large energetic proton events up to hundreds of MeV. The a-Si:H presents an excellent radiation hardness and finds application in harsh radiation environments for medical purposes, for particle beam characterization and in space weather science and applications. The critical flux detection threshold for solar X rays, soft gamma rays, electrons and protons is discussed in detail.

The characteristics of a hydrogenated amorphous silicon (a-Si:H) detector are presented here for monitoring in space solar flares and the evolution of strong to extreme energetic proton events. The importance and the feasibility to extend the proton measurements up to hundreds of MeV is evaluated. The a-Si:H presents an excellent radiation hardness and finds application in harsh radiation environments for medical purposes, for particle beam characterization and, as we propose here, for space weather science applications. The critical flux detection limits for X rays, electrons and protons are discussed.
