    Abstract: A project on development of a satellite-borne silicon-based cosmic ray ion detector was started. Semiconductor detectors based on P-I-N junctions are widely used in space experiments due to their light weight, compact design and high stopping power. The position-sensitive parts of the detector are designed to be silicon-based detectors. A prototype silicon detector without the outermost layer of insulators was prepared. The detector is expected to have the potential to identify the elements of high energy ions using the ΔE-E technique. Thus, for the beginning step of this project, a detector response proportional to the deposited energy has to be confirmed. We set up a detection system of a mixed standard alpha source including Am-241, Pu239 and Cm-244 with our devices and a photodiode (Hamamatsu S1223 with glass removed). The detector response is indicated by the digitized signal pulse height distribution from a 2048-channel ADC. The feasibility of our devices to distinguish the difference of energy in terms of several hundred keV was confirmed. A linear relation between the pulse height peaks and the emitted energy of each radiation source was also indicated.

    Abstract: Observing cosmic rays and solar energetic particles provides important information about the solar wind and solar storms. We are working toward building a Thai detector of energetic ions from space that is inspired by the Mass Spectrometer Telescope (MAST), a satellite-based detector installed on SAMPEX of cosmic ray ions with the energy range of 0.01 to 0.5 GeV/nucleon with the objective to determine the nuclear charge and kinetic energy for nuclei with atomic number of Z = 1 (hydrogen) to 28 (nickel). The energy range of the detector covers the energy range of anomalous cosmic rays, Galactic cosmic rays and solar energetic particles. Therefore, observations by such a detector can provide insight into the origin and transport of these ions in cosmic rays and solar energetic particles. During solar events, measurements of the elemental composition of solar energetic particles can be compared with the composition of the solar corona. We have created a computational model of the MAST detector to simulate ion detection using the FLUKA program to measure the energy deposition of heavy ions in multiple detector components to determine their initial kinetic energy in the simulation. From the simulation results, we can identify the ions’ energies and species using established methods and calculate the geometry factor of the detector, comparing the results with previous reports.
