BDS Bubble Neutron Detector

BDS Bubble Neutron Detector

Product introduction           

The BDS is a complete low-cost neutron spectrometer package packed with 36 bubble detectors that have been specially formulated for six different energy thresholds. Each spectral measurement can use 18 detectors (3 each providing a threshold of 10, 100, 600, 1000, 10000, 2500keV). The detector can be reused by repressurizing the pressure chamber.

Technical parameters

• Energy range: Six thresholds: 10, 100, 600, 1000, 2500, and 10000keV

• Dose range: ~50 mrem, ~535 μSv

• Sensitivity: 1~2 bub/mrem, 0.1~0.2 bub/μSv
