Sun Nuclear manufactures products using diode and ion chamber detectors. Both detectors offer unique advantages based on the application. Due to their small size however, diodes more accurately measure and characterize the properties of small beams and penumbra than ion chambers. When millimeters are critical, this increased accuracy can have a profound impact on the patient. For this important reason SunPoint Diode Detectors are selected as the detector of choice for many Sun Nuclear products.

Sun Nuclear has invested in detector design for over 25 years. A result of our dedication to research in new technology is the SunPoint Diode Detector. In use since 2001, SunPoint Diode Detectors offer superior performance and outcomes in applications where small beam penumbra and intensity modulation are being measured. SunPoint Diode Detectors also provide:

• Absolute dose measurement
• Excellent stability (+/- 0.5% over 100,000cGy)
• Long lifetime ( > 10,000,000cGy)
• Excellent sensitivity characteristics (32nC/Gy)
• Negligible dose rate dependence
• Negligible energy dependence

The SunPoint name distinguishes Sun Nuclears SunPoint diodes from other diodes. Products using SunPoint Diode Detectors include: ArcCHECK, MapCHECK 2, MapCHECK, Edge Detector, SRS PROFILER, PROFILER 2, TomoDose, QED, and Daily QA 3.
