InterWinnerInterWinner 7.0 is a universal nuclear spectroscopy

analytical program simultaneously controlling up to32 inputs. InterWinner provides different analysis
engines for Germanium, NaI, LaBr and CZT based
gamma spectroscopy as well as solid state Alpha
spectroscopy. InterWinner is available in versions
to support several or all of these detector types.
InterWinner controls all detector, amplifier and ADC

setup parameters as well as data acquisition parameters and spectrum storage. InterWinner incorporates
complete qualitative and quantitative analysis containing modules for all auxiliary data files necessary forthorough interpretation, research and sophisticatedreport generation. Through a multi-document baseduser interface, InterWinner offers the possibility todisplay in multiple windows as many as 1024 different

spectra and an unlimited number of regions of interest of any of the individual spectra. Spectra currently
in acquisition or loaded from hard disk are shown andcan be handled synchronous, while all the auxiliary
data files (such as isotope tables) are handled in thesame interface plus many can be loaded parallel.

User Interface FeaturesInterWinner is not bound to the MCA hardware

delivered by Itech Instruments but can be used withnearly every commercially available MCA with thesame full hardware functionality and spectral analysis
InterWinner‘s user interface allows for effective management of spectra and data. The tool bar includes
all necessary and useful functions for the currently
selected file or live spectrum acquisition. The icon
bar displays the real time status of all inputs. Theseon-screen aids make InterWinner a powerful andeasy to use tool for modern nuclear spectroscopy.

ties will be shown if desired. During the acquisition allthese afore mentioned data will be frequently updated.

InterWinner not only provides the simultaneous

display of different spectra and auxiliary files but
also ensures effectiveness through various helping
devices in the area of spectrum analysis and particularly useful means to be fitted for the needs of multiple users without interfering with analysis quality.

For the desired presentation of spectrum, InterWinner
offers the user a wide range of display modes. You
can chose to have the channel points joined andpeaks filled, or not. The display can include a gridwith choice of horizontal or vertical lines or bothand the X and Y axes can be shown or hidden.

In a spectrum InterWinner is capable of labelling
peaks automatically plus peak fit, peak areas and activi-

The vertical scale offers auto ranging in the linear,square root or log styles. The horizontal axis will

toggle between energy and channels. The Display
options dialog box also includes the choice of displaying other relevant information for both full spectrum
and individual region of interest and peak data.

quired information. For example, clicking on a peakenergy in the report opens a spectrum window whichshows the peak concerned. Sample changer control
is also available. This module allows for preparing
the acquisition and analysis parameters for up to 100
samples which will then be processed automatically.

Once the manager or user settles on a particular list of
display options, these settings can be set into the user
defaults. InterWinner includes the option of allowing
the spectroscopist the ability to write notes or annotations directly into the spectrum display and allowing
these comments to be printed and stored with thespectrum. Furthermore parameter files allow preparing all of the acquisition and analysis parameter inadvance. In reports shown on the screen hypertextlinks (marked in green) lead the user fast to the re-InterWinner also includes a spectrum finder func-tion which is used to find a spectrum on disk using
many different criteria such as acquisition date range,reference date range, comments, or other criteria.
The InterWinner interface can be controlled
and modified using the integrated scripting language. User specific buttons can be added toITECHINSTRUMENTSthe tool bar and menus can be adapted by adding, removing or replacing menu items.

For every gamma analysis performed with Inter Winner, the following corrections are always considered:InterWinner always includes English, German and► Isotope gamma emission probability using user-modifiable isotope libraries► Energy dependant efficiency correction► Spectrum/Compton background subtraction► Either background peak subtraction orbackground spectrum correction► Decay correction including parent/daughter in-grow determination► Correction for absorption inside the sample
and between sample and detector (self-attenuation and attenuation shield)

French languages. Users can define the settings forlanguage, color and display modes independently.
The analysis of any spectrum in InterWinner can
be started during it’s acquisition and is frequently
updated while the new data is acquired. This includes both qualitative and quantitative analysis.
Thus peak search and ID allows for quick ID ofpeaks as the statistics allow and the various peakfitting and deconvolution techniques available inInterWinner will occur automatically if desired.

Energy and resolution calibration can be performed
and the parameters can be stored, either manually,library assisted or fully automatically. A calibration
report is produced and will be accessible throughan hypertext link from the analysis report of every spectrum analyzed with this calibration.
InterWinner fits peaks and deconvolutes multiplets.

The model peak used can be parameterized and depends on the detector and analysis types thus giving
the best results for Germanium, Sodium iodine andAlpha grid chamber or Alpha semiconductor detectors.

Main Analysis Features

In InterWinner the activities are calculated per line
and also averaged over all lines of the radionucleide. Theresults are shown on screen, and are available for printing or transfer to a data base. Data bases directly compatible are either text form (CSV) or ODBC controlled
data bases, including Microsoft Access and SQL Server.

InterWinner features an interactive analysis including

a graphical display of the calculated background and fit
and the possibility to insert or suppress peaks manually.
An efficiency calculation and modelling tool, named
WinnerTrack, is available as add-on. This tool takes
the information about the detector details and lets
the user model his acquisition setup using an interactive three-dimensional display. It then calculates anefficiency curve which can be used in InterWinner
in the same way as an experimental curve.
WinnerTrack is available for NaI

and Germanium detectors.

WinnerScan is a tool which creates charts showing

activity vs. time or space. It can be used in an onlinemode where WinnerScan controls the acquisition andalso in an offline mode where acquisitions are mademanually and later imported into the WinnerScan file.
