- Leading radiation hardness and leakage characteristics for better data quality
- Water-equivalent housing using HE Solid Water®
- Clearly marked housing for simplified setup
- Consistent detector-to-detector performance enabled by tighter mechanical tolerances
- Low dose per pulse dependence
SunSILICON™
An unshielded silicon diode detector
for relative electron and small photon
field dosimetry
| Field Size Range | (1 x 1) cm² to (10 x 10) cm² (photons) (1 x 1) cm² to (40 x 40) cm² (electrons) | |
| Smallest Field Size* | (0.4 x 0.4) cm² |
* Refer to IAEA TRS-483 or AAPM TG-155 for the methodology of applying field output correction factors to ensure high-accuracy output factor measurements in very small photon fields.
SunSILICON Lateral Beam Scans: Excellent performance in lateral beam profile scans of small to medium field sizes and against best-in-class current technology.
SunSILICON Field Output Correction Factors: Significantly improved TRS 483 / TG 155 small field output correction factors and improved field size range.
SunSILICON - Percentage Depth Dose
For Electron Beams (Left): Excellent performance in electron beams in both PDDs and lateral beam profiles (Note: A parallel plate chamber can only be used for PDD measurements.)
For Photon Beams(right): Excellent performance in PDD/TRP scans of small to medium field sizes. Excellent performance against best-in-class current technology
