BrightSpec MCAsCompact digital multichannel analyzers for gamma spectroscopy.

BrightSpec digital MCAs are compact, stand-alone analyzers that perform pulse height analysis on signals from scintillation and semiconductor detectors. Paired with PMTs, SiPMs, HPGe, and CZT, they cover gamma spectroscopy, radionuclide identification, and pulse processing for research, the nuclear industry, and medical work.

Made by BrightSpec, represented in North America by Berkeley Nucleonics.

The BrightSpec line

Seven ways to read out your detector.

From miniature SiPM analyzers to high-resolution HPGe and CZT MCAs, plug-on modules, and the bGamma analysis suite, BrightSpec covers pulse height analysis end to end. Pick the group that matches your detector, then open the datasheet that fits.

BrightSpec TOPAZ-SiPM miniature digital multichannel analyzer

Topaz digital MCAs

3 models · SiPM, HPGe/CZT, and portable

Fully digital, stand-alone multichannel analyzers. The Topaz-SiPM serves silicon-photomultiplier scintillation detectors, the Topaz-HR reaches 16K channels for high-resolution HPGe and CZT, and the TOPAZ-Pico packs up to 4096 channels into a portable stand-alone unit.

BrightSpec bMCA-Ethernet plug-on digital multichannel analyzer

bMCA plug-on MCAs

2 modules · USB or Ethernet

Compact, fully digital MCAs that plug directly onto a standard 14-pin PMT and read out NaI(Tl), LaBr3(Ce), LaCl3(Ce), CeBr3, and similar scintillators. Choose the bMCA-USB for a direct PC link or the bMCA-Ethernet to sit on a local network.

BrightSpec bPAD compact single channel analyzer in a PMT base

bPAD single-channel analyzer

1 channel · preamp, amp, and discriminator

A microprocessor-based single-channel analyzer that fits a preamplifier, amplifier, and discriminator into a compact photomultiplier-tube base. It suits counting and gating work where a full spectrum is not required.

BrightSpec TOPAZ-Pico MCA running under bGamma spectroscopy software

bGamma software

Windows, Linux, and macOS

The bGamma package drives gamma-ray spectroscopy analysis across the BrightSpec MCAs. It handles radionuclide identification, quantification, and data analysis, so one tool covers acquisition through reporting.
