Berkeley Nucleonics Corporation (San Rafael, CA) and Princeton Gamma Tech (Princeton, NJ) have partnered to offer gamma spectroscopy with either germanium or sodium iodide detectors. A complete line of portable and benchtop systems will meet your spectroscopy needs. See www.pgt.com or www.berkeleynucleonics.com for the latest product information. QuantumGold QuantumGold, the premiere software package for qualitative and quantitative gamma analysis, is a true 32-bit application compatible with Windows 95/98/NT. Some of the exciting features of QuantumGold are: Simple, easy-to-understand user interface Multiple memory groups for processing spectra Peak deconvolution Quantitative analysis of spectra taken with germanium or sodium iodide detectors Ethernet network support for PGT multichannel analyzers One year of free software upgrades with a new purchase of QuantumGold QuantumMCA QuantumMCA is a multichannel analyzer emulation package which is supplied with all PGT multichannel analyzer instruments that require computer control. QuantumMCA allows you to perform the fundamentals of qualitative gamma spectrum analysis as well as to control all hardware functions. Its analytical tools are easy to use, with a visually intuitive user interface to make it easier to find commonly used functions. Qualitative Analysis The primary function of qualitative analysis is peak search and isotopic identification. The Tools Setup window gives you a powerful and flexible way to control these functions. All parameters associated with the peak search routine, ROI definitions, and many other basic analytical functions are defined in this window. The interactive peak display feature shows how the peak ROI is affected by the width parameters. As a parameter is changed, the graphical display is updated automatically. While some users prefer an automated approach to pulse height analysis, you may want to set and adjust ROI s manually before the peak information is calculated. Simply use the mouse and the Ctrl key to draw out each ROI. To adjust an ROI, just click the mouse cursor in the ROI to select it and then use the lower tool bar buttons to make the desired changes. The software can even deal with overlapped ROIs.

Quantum Software Intuitive user interface Easy to use analysis functions Toggle buttons through multiple selections Easy-to-use Tool Tips for Control displayed range menus all buttons with buttons or mouse Display up to 8 spectra, from as many as 8 different spectrometers or MCAs or from disk. Auxiliary display for full spectrum, convolution results, hardware controls.

The information and data displays are intuitive and easy to understand. Consider the efficiency calibration process: simply open the detector calibration window, select the gamma lines that you wish to use for the calibration, and then press one button. The efficiency curve is automatically generated and displayed on the screen.

Calibration Certificate Database QuantumGold manages the certificate information for any number of calibration standards in a Microsoft Access database. Information on each standard, including those with multiple nuclides, can be entered into this database via a data entry window in the software. Decay corrections are then automatically performed when a particular standard is used in the calibration process. Peak Deconvolution QuantumGold performs a gaussian peak deconvolution to analyze spectra with overlapped peaks, including multiple overlapping ROIs within a multiplet. ROIs can also be manually inserted or removed and the deconvolution analysis repeated. Nuclide Library Quantum software includes three main libraries, each of which is tailored to a specific type of spectroscopy: Agamma library with over 100 isotopes, hundreds of gamma emissions, and numerous X-ray emissions associated with some radioactive decays An alpha library with 63 nuclides and 193 associated alpha emissions. Abeta library with 59 nuclides and 120 associated beta emissions. Libraries can be cloned and readily configured for specific applications. User Defined Spectrum Analysis For users who want to perform a more custom-oriented interactive data analysis, the "Convolutions" menu provides several functions that manipulate the acquired spectrum and place the result in a separate memory location for display and analysis. The available convolution filters include the following: Quadratic Smooth Top hat filter 1st and 2nd derivatives Peak finder Spectrum Calculator is a handy way to perform spectrum manipulation, such as adding spectra, subtracting, and other basic calculations. After the specified spectrum processing has been carried out, the software uses an available memory buffer to store/display the resulting spectrum.

Analytical Methods There are two analysis methods available in QuantumGold: library directed and ROI directed. The library-directed method first performs an automatic peak search according to the parameter settings in the Tools Setup window, with deconvolution if peak deconvolution has been selected. Peaks are then matched to the library lines of selected nuclides, and the nuclide identification is made accordingly. The next step involves the calculation of nuclide activities based on the efficiency correction data. Finally, the sample analysis report is generated, which displays activity information on the identified nuclides in order of level of confidence. The ROI-directed method allows a particular ROI to be manually assigned by the user to a specific gamma emission of a particular nuclide. This analytical method does not involve a peak search or library search for selected nuclides. An activity calculation is performed according to the net counts in each assigned ROI. This method can be particularly useful when an analysis needs to be performed on a specific list of nuclides that are known to be present. By the very nature of this method, nuclides that may be in the sample, but are of no interest, are automatically excluded in the analysis. One useful feature of this method is that MDAs are reported even when no net counts are measured for a particular ROI. QuantumMCA Reports QuantumMCA also generates several reports that give data in a useful concise format. These reports include: Channel data ROI data ROI detail Peak search Peak identify

Automated Control If you need to customize the operation of the software for a particular application, Q-Script is a flexible and easy-to-use software automation development tool. It has a menu-driven, design interface that allows you to construct an automated MCAbased sample counting and analysis routine. A comprehensive selection of commands is available. Q-Script commands can even allow the software to designate the values of logic signals on the rear panel auxiliary I/O connector of PGT multichannel analyzers. These logic signals can be used to control the actions of external hardware that accept control signals in this manner (e.g. a sample changer). Hardware Adjustment and System Calibration Automatic hardware adjustment of PGT gamma spectrometers is as simple as placing a Cs137 source near the detector and pressing one button. For sodium iodide based systems, the detector high voltage, coarse gain, and fine gain are automatically set. For safety purposes with germanium detector systems, the detector high voltage is set and adjusted manually. On both types of systems, automatic fine energy calibration is also available. Place a multi-line source (such as Eu152) near the detector, take a spectrum, and press the "Fine Energy Cal" button. A quadratic energy calibration is performed on the spectrum in memory. For a resolution calibration, you can use the same spectrum. Of course, if you prefer the manual method for setting the hardware and performing energy and resolution calibrations, this is also possible via the PC. Total hardware control via Quantum software makes for easy setup. The software also includes the facilities for a quick manual linear two-point energy calibration and a manual quadratic ROI centroid based method. You can also do a manual resolution calibration if desired.

Quadratic Compression Conversion (QCC) Quadratic Compression Conversion represents the first major development in scintillation spectroscopy in nearly 25 years. NaI detectors have always been attractive for nuclear spectroscopy because they have reasonable energy resolution, are rugged, do not require cryogenic cooling, are physically small and have reasonably low cost. Unfortunately, NaI detectors suffer from a variety of problems such as: a non-linear response below about 200keV, low resolution compared to some other detectors, resolution that is a significant function of the gamma energy. QCC is a patented (#5,608,222) technology that minimizes these inherent drawbacks and significantly enhances the ability of the software to identify peaks and make the associated isotopic identifications. This technology is implemented in the MCA2100R and MCA2100 gamma spectrometers. For more information on QCC, see the product information sheet entitled, "Quadratic Compression Conversion - A New Way to do NaI Gamma Spectroscopy." Low energy peaks better defined 8000 channel linear spectrum of 60Co and 133Ba High energy peaks better defined 512 channel linear spectrum of 60Co and 133Ba All peaks equally well defined Networking and Communication with the MCA Hardware 512 channel QCC spectrum of 60Co and 133Ba The modern lab frequently has applications where more than one MCA needs to be connected to a single PC. Quantum software and PGT multichannel analyzer hardware address this requirement with two interface technologies: Ethernet (10/100 base-t) and RS232. No slots in the PC are required to use any PGT instrument. Likewise, the data from each instrument is managed by Quantum software in a logical and easily understood manner. Multiple spectrometers or MCAs can easily be controlled via one software package. The user can control whether to display the spectrum, not display it, copy it to new memory buffer, or delete it from memory. The number of memory buffers at this time is eight, and consequently, a maximum of eight PGT spectrometers and/or MCAs can be controlled by the Quantum software. PGT multichannel analyzers that are available with Ethernet include: MCA 2100R MCA 8000 Multichannel Analyzer System 8000 Gamma Spectrometer A convenient hardware search program is used to establish communication between all PGT MCAs that are connected to the local area network (LAN) via Ethernet (10/100 base-t) or the on-board RS-232 interface. By virtue of this hardware search technique, QuantumMCA automatically configures itself for the capabilities of each piece of hardware.

Supported hardware All PGT and BNC MCA's are compatible with QuantumMCA, the basic software package with no quantitative analysis capability. The list currently includes the following instruments.
