2BY2/2BY2-DD 3BY3/3BY3-DD Integral NaI(Tl) Detector 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" or 3" 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 ScintiPackTM 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 highrate operation with minimal peak shift. ScintiPack’s ultra-low power consumption (240 mW) makes it attractive for portable ap

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. Electrical and Mechanical Power Required 2BY2 or 3BY3 +12 V at 20 mA. Supplied via a captive power cord terminated in a standard preamplifier power plug (9-pin D connector). Power cord length is nominally 3 m or 10 ft....
