Direct Dose Detection (D3)
Direct Dose Detection or “D3” is a hybrid semi-conductor detection system, capable of converting photon energy into digital signals.
D3 combines a top substrate (either Cadmium Telluride (CdTe), Cadmium Zinc Telluride (CZT) or depleted Silicon (Si)) with a bonded lower substrate (CMOS ASIC). This technology offers a unique, versatile platform that maintains accuracy and does not saturate regardless of circumstances; therefore has the capability to detect a broad range of radiation activities.
why choose the Direct Dose Detection (D3)?
✓ the system architecture ensures on chip, off chip processing
✓ energy discrimination, identify specific isotopes
✓ flexible detector configuration
✓ minimal user training required
✓ highly portable, small, lightweight
✓ can be used for real-time, distributed monitoring
✓ wide dynamic range (0.1µS/vh- 1Sv/h)
✓ energy discrimination
✓ modular architecture
Known as the Solid State Neutron or “SSN”, these detectors are novel, versatile alternatives to He-3 technology .
Pin diodes and either B10 ( for higher gamma discrimination) or Gd (for higher neutron sensitivity) are layered alternatively on thinned silicon wafers to create a neutron packet. The number of layers can be determined by the customer (1-5 layer options). The neutron packets are then integrated into customer products, to produce highly sensitive neutron detectors.
why choose the Solid State Neutron (SSN)?
✓ High neutron sensitivity
✓ High background rejection
✓ High gamma rejection
✓ Low power consumption
✓ Easily integrated with digital interfaces
✓ He-3 replacement
✓ Uniform response in azimuth
✓ Ideal for neutron imaging
✓ Detect extremely low neutron fluxes
