HyperLab 2023 product information

HyperLab is a full-fledged gamma spectroscopy software system, used by many research and industrial laboratories worldwide. If you want a well designed, superior quality, reliable, yet visually rich gamma spectrum evaluation, try out our HyperLab 2023 software package. HyperLab's various automatic features will save a great amount of your precious time. See also our online HyperLab 2023 documentation for details.


  • superior quality automatic gamma spectrum deconvolution
  • processing of Canberra's Dual LFC and Ortec's ZDT-VAR spectra
  • visually rich representation of deconvoluted regions, revealing fine details
  • full arsenal of manual deconvolution adjustment tools
  • SQL database back-end for spectrum and peak list storage
  • detector efficiency and system nonlinearity evaluation
  • handles most popular spectrum file formats (Canberra's CNF, Ortec's SPC, MCA, Accuspec, ANSI-N42, etc.)
  • ... and much more!


  • Much better automatic fit of complicated regions than its competitors: less manual interventions.
  • Loss-free counting evaluations: changing count rate is no more a problem.
  • What you see is what you get: no more blind deconvolutions.
  • Full manual control of fits: perfect fits are just a few clicks away.
  • SQL database: forget the long inventory of spectrum and evaluation files.
  • Nonlinearity and efficiency correction: exact peak locations and areas for further processing such as isotope identification and activity calculation.

Automatic fitting of extremely complex regions

  • Automatically locates peaks, requires only a rough FWHM calibration
  • Intelligently determines real peak width, location, amplitude, skew, etc.
  • Uses semi-empirical peak and background functions
  • Background is made of slope, curve, step, skew parts, able to describe all real cases
  • Nonlinearity and efficiency correction: exact peak locations and corrected peak areas
  • Region backgrounds are overlapping by default, so more stable fits may be achieved

Quick, visual fit refinement

  • Region fit manipulation by the mouse over the visual representation of the region fit
  • All parameters of the fit may be adjusted by hand, changes are immediately displayed on the fit chart
  • Quick peak addition, removal, as well as region split and merge operations by mouse
  • Visual FWHM and Energy calibration with quick point addition and removal
  • Residual is always visible and helps the manual intervention greatly

Automatic annihilation peak fit

  • HyperLab is able to use a Variable Peak Width method, when all peaks within a region may have significantly different FWHM
  • Significant lines may be resolved automatically which are overlapping with the 511keV annihilation peak
  • Parameters of the allowed broadening may be adjusted, if necessary

Batch evaluator

  • Performs deconvolution of multiple spectra without user intervention
  • Stores the deconvolution results into the database, TXT or Sampo-90 files
  • Results may be later hand-tuned in the database, with the same set of tools as for individual evaluations
  • RTF report files optionally with graphical representation of the fits
  • Quick results of well-known spectra within minutes

Detector efficiency determination module

  • Automatically constructs an absolute or relative full-energy detector efficiency curve
  • The curve is fitted with one single polynomial, with a numerically very stable method (orthogonal polynomials)
  • Multiple measurements with multiple isotopes may be used, even with home-made sources
  • Achievable precision is around 1% - 0.5% when multiple sources are used with activity calibration. Suggested sources: 133-Ba, 152-Eu for 200-1400keV range, and 241-Am, 109-Cd, 57-Co for the 50-200 keV range. For furher improvements, utilizing 75-Se, 110m-Ag and 56-Co sources are also advisable.
  • Individual lines may be manually removed if proved to be unappropriate
  • The efficiency curve may also be used for generating efficiency-corrected peak reports
  • Activity of home-made sources may also be calibrated

System nonlinearity determination module

  • Automatically contructs a nonlinearity curve, which describes the deviation from the ideal channel-energy calibration line
  • Multiple measurements may be used, if the identified lines of isotopes are overlapping
  • The resulting curve may be used to remove nonlinearity from the energy calibration
  • This way the deviation of peak positions from the true value may be reduced to 0.01keV in the whole range

Structured information storage in SQL databases

  • Contains specta in compressed form, as well as peaks, nuclear data, and all other information required for routine processing
  • Replaces miriads of small spectrum, calibration, DOC, etc. files used by conventional systems
  • Provides one independent storage location for all the laboratory's work - a major step towards the paperless bureau
  • Enforces strict logical relationships, therefore minimizes chance of improper user input
  • Helps Quality Assurance
  • Excellent for post-processing, e.g. for Excel, utilizing ODBC connections

Integrated nuclear library

  • Contains several hundreds nuclides, isomer states and decays
  • Assembled from ENSDF data files
  • Stored in HyperLab's database, also available to post-processing tools
  • Individual radiations may be flagged for usage in energy, FWHM calibration, efficiency evaluation etc.
  • All values may be edited, thus enabling correction of problematic data
