14-Pin PMT Tube Base with Integrated Bias Supply, Preamplifier, and MCA (with Digital Signal Processing) for NaI Spectroscopy.

The digiBASE is a 14-pin photomultiplier tube base for gamma-ray spectroscopy applications with NaI(Tl) scintillation detectors.

The unique concept of the digiBASE combines a miniaturized preamplifier and detector high voltage (0 to +1200 V bias) with powerful digital signal processing, multichannel analyzer, and special features for fine time resolution measurements — all contained in a low-power (<500 mA), lightweight (10 oz, 280 g), small-size (63 mm diameter x 80 mm length) tube base with a USB connection. Everything you need to connect to your NaI(Tl) detector is included in the tube base. Furthermore, there is no need to open your computer to install an interface card, or for using external NIM-based components.

  • Full featured digital MCA and gain stabilizer for ultimate stability
  • Fast data acquisition for maximum throughput
  • The ultimate in Fine Time Resolution with “List Mode”
  • Multi-detector arrays made simple with USB Connection
  • 0 to +1200-V Detector Bias Voltage
  • Software included: ORTEC’s MAESTRO-32 advanced MCA software. ScintiVision or InterWinner (optional)
