ORTEC 2BY2/3BY3
Integrated 2 × 2 and 3 × 3 in NaI(Tl) probes for field spectroscopy
Complete NaI(Tl) probes for in-field gamma spectroscopy: crystal, photomultiplier and PMT base with integral preamplifier and high voltage in a rugged aluminium housing. A single cable carries both power and signal; the DD versions connect directly to the digiDART or digiDART-LF.
- Detector type
- NaI(Tl) crystal with photomultiplier and PMT base with integral preamplifier and HV supply, in an aluminium housing1

Overview
Key features
- Low power (240 mW) – suited to portable systems
- Active bias network for high-rate operation with minimal peak shift
- Optional break-out adapter for a BNC signal (296-ADAPT)
