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.

Neutron Detection

 

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
