The neutron detector LB 6419 (Pandora) is designed to derive dose and dose rates at particle accelerators. In this environment, very specific conditions for dose monitoring prevail like pulsed radiation or high beam energies. Many conventional measuring devices for ionized radiation suffer greatly from dead-time effects and are therefore only limited suitable for the measurement of pulsed radiation fields. In addition, many types of detectors do not have the necessary sensitivity at high energies or high dose rates and tend to underestimate the radiation field intensities significantly.

The Dual Detector Design is patented and provides outstanding features. Whereas prompt neutrons can be detected in the 3He tube, those from pulsed sources produce short lived reaction residuals in the plastic scintillator or the surrounding which are observed with very high efficiency. The dose is derived from the intensity of those residuals between the pulses. Under typical pulsed beam conditions the probe does not suffer from saturation effects up to neutron dose rates of ~1 Sv/h in the burst. The primary reaction channels are: 12C(n,p)12B, 12C(n,pα)8Li, 12C(n,p3He)9Li. Furthermore, the gamma dose rate in the pulse can be detected with the plastic scintillator as well.

The Dual Detector Design provides in addition a security far better than any other REM counter. Both detectors are applied independently and control themselves mutually. Two independent interlock signals round out the security concept.
