“…Conversion to the mean chord length in tissue requires the use of a scaling coefficient, . In previous work with the SOI microdosimeter such a scaling coefficient has been established as 0.63 [13], [21]. As such the mean chord length in tissue for the SV employed in this work was 7.936 m. This value was used for the generation of TE lineal energy spectra and dose mean lineal energy values.…”

Abstract-This work provides information pertaining to the performance of Silicon-On-Insulator (SOI) microdosimeters in heavy ion radiation fields. SOI microdosimeters have been previously tested in light ion radiation fields for both space and therapeutic applications, however their response has not been established in high energy, heavy ion radiation fields which are experienced in space. Irradiations were completed at the NASA Space Radiation Laboratory at BNL using 0.6 GeV/u Fe and 1.0 GeV/u Ti ions. Energy deposition and lineal energy spectra were obtained with this device at various depths within a Lucite phantom along the central axis of the beam. The response of which was compared with existing proportional counter data to assess the applicability of SOI microdosimeters to future deployments in space missions.

“…The widespread study on silicon diodes performance in the spectrometry of charged particles is due to the possibility of their use as a research tool, both in laboratory and in industrial applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], as the measurement of the isotopic ratios between chemical elements. In order to employ this technique in studies related to reactor fuel elements and their properties after irradiation, we have been studying the response of silicon diodes for alpha spectrometry.…”

On the origin of the satellite peaks in alpha particle spectra

In this work we describe the results obtained with S3590-06 and ion-implanted diodes for alpha particle spectrometry. Satellite peaks were also investigated in order to identify not only the origin of these phenomena, but also the importance of the guard ring region on their relative intensities. The preliminary results indicate that the true cause of the spurious satellite peaks might be associated with the weak electric fields around the guard rings region and changes on the entrance window absorption near the edge of the diodes. Further steps are needed to clear up this problem.

“…These devices have been successfully tested for applications in radiotherapy [5], [6], radiation protection [7], and deep space environments [8]. It was reported that this array design has a poorly defined charge collection volume that can be taken into account by the introduction of a charge collection efficiency (CCE) coefficient [4]- [6].…”

Abstract-Recent developments in the fabrication and simulation of prototype silicon-on-insulator (SOI) microdosimeter arrays are presented. A new planar array design has been proposed which has a number of advantages over the previous elongated parallelepiped and cylindrical mesa array designs. This novel planar array design, which incorporates a guard ring, is based upon 2500 planar cylindrically shaped p-i-n detectors and was fabricated via dopant diffusion and ion implantation. The dopant-diffused arrays were successfully fabricated and tested using 2 m and 10-mthick SOI substrates. Technology computer-aided design modeling of the ion-implanted structure is presented which includes the electrostatic potential profile, showing possible avalanche signal multiplication around the + core of the microdosimeter. The alpha particle charge transient response was simulated to determine the charge collection in the sensitive region.Index Terms-Avalanche signal multiplication, microdosimeter, p-i-n detectors, silicon-on-insulator (SOI), SOI substrates, technology computer-aided design (TCAD) modeling.
