| 摘要 |
The invention proposes a device (10) for characterizing an ionizing radiation used in an ambient medium having a first refraction index (n1), the device (10) comprising: a scintillator material (12) delimited by a wall (28), the scintillator material (12) generating photons under the effect of an ionizing radiation, the scintillator material (12) having a second refraction index (n2), and a guide layer (16) in contact with at least part of the wall (28), the guide layer (16) guiding, toward a predetermined zone, the photons generated by the scintillator material (12) and having an angle of incidence relative to the part of the wall (28) greater than or equal to the arcsin of the ratio of the first refraction index (n1) to the second refraction index (n2). |
