Complete Rugged NaI Detector Probes for In-Field Gamma Spectroscopy Measurements

• Rugged integrated NaI detectors in tough aluminum housing — available in 2″ x 2″ and 3″ x 3″ sizes.
• Integral preamplifier and high voltage (HV) for convenience and safety.
• Low power consumption (240 mW), ideal for portable applications.
• Single-cable connections for most applications.
• 2BY2-DD and 3BY3-DD available for use with ORTEC digiDART and digiDART-LF.

Everything You Need in One Compact Package
2BY2 or 3BY3 is a complete NaI(Tl) probe, ready to go to work in your application. Each models contains a NaI(Tl) crystal (2″ x 2″ or3″ x 3″) with photomultiplier tube (PMT) and a PMT base with integral preamplifier and HV supply securely encased in a compact aluminum housing.

Ultra Low Power; the End of Bulky, External, HV Supplies
The model 296 ScintiPack PMT base includes a low-power, adjustable high-voltage supply, an active bias network, and a charge-sensing preamplifier. Incorporating the bias supply in the PMT base eliminates high voltage cable connections to bulky, external, HV supplies.The ACTIVE bias network permits high-rate operation with minimal peak shift. ScintiPack’s ultra-low power consumption (240 mW) makes it attractive for portable applications.

Single-Cable Operation
A single cable supplies power to the preamplifier and the HV supply as well as the signal out of the preamplifier. For the “-DD”versions, the connection is direct to the digiDART or digiDART-LF (also other ORTEC DSP spectrometers).An optional break-out cable can be used with the model 2BY2 or 3BY3 should you want the signal on a BNC output connector.
