Upgrading from Version 5.0
The major enhancements brought to GammaVision-32 V5.0 are:
-
New ROI-32 Analysis Engine
For the user who needs to mark specific Regions-of-Interest for nuclides
within their library, we now have an analysis engine designed to do just
that. Designed for the highly technically qualified user, this engine should
be used with caution. The user manual gives specific cautions and guidelines
for using this engine. For those that do choose the ROI-32 engine, they can
analyze Live spectra or Archived spectra.
-
Improvement to the Total Uncertainty Calculation
Previous versions of GammaVision included options for calculating Total
Uncertainty (TPU). However, the user was limited on the type of distribution he
could apply to the specific uncertainty terms. With the latest version of GammaVision-32, the
user can define their uncertainty terms, and decide how to propagate the terms.
The user has the option of treating their additional uncertainty as a uniform
(rectangular distribution), or a normal distribution. The software will apply
the correct mathematical propagation of the Total Uncertainty.
-
Two New “Hot Buttons” Added to the Toolbar
The Sample Type Settings button will immediately open the dialog that
controls the current analysis settings for the detector or buffer selected.
This duplicates the Analyze/Settings/Sample type (three mouse clicks)
operation on the main tool bar.
The Analyze Spectrum button will immediately analyze the spectrum selected.
This duplicates the Analyze/Entire Spectrum in Memory (two mouse clicks)
operation on the main tool bar.
-
Create PBC Function Added to Peak Background Correction
Menu
This allows the user to more quickly create and save a background file. In older
versions of GammaVision, this function required multiple steps and was prone to
user error. Now, the user utilizes the Browse and Save functions to easily
associate the Background spectra to a file.
-
Enhanced User Manual
Table to assist user in selection of the proper Analysis Engine
Clearly defined explanations of the MDA options
Thorough explanation of the various ZDT modes
Detailed explanation of the QA parameters that are monitored
- A New Multi-Detector Interface
With the new GammaVision, your entire laboratory can be visible
within the GammaVision program interface. The new Mutiple Detector Interface
in GammaVision allows viewing up to 8 Detector and 8 Buffer windows
simultaneously for a total of 16 interactive windows. Controlling multiple
detectors, visually comparing spectra, and viewing multiple MCB properties is
now easier than ever!
- Simple Simultaneous Acquisition Control
The new interface not only allows viewing and comparing of spectrum
windows, but also for maximizing sample throughput in your lab. You can begin
acquisitions of multiple samples or select one detector at a time.
Synchronizing data acquisition on multiple detectors simultaneously is now a
snap! Acquisition options allow for automatic acquisition for a group or
single detector. The analyst can be prompted for acquisition options when
acquisition is stopped and started, or the preferred option can be
predefined. The new features are sure to improve the performance of your
lab…..and FAST!
- Display Analysis Results
Spectral displays are now more powerful than ever with peak nuclide
identification, absolute and relative residuals, and a variety of flexible
display properties for every aspect of the spectrum display. It has never been
easier and faster to identify a full-energy peak than with the new Analysis
Results Display!
- The New Winplots
The new GammaVision improves not only your ability to quickly and
easily identify and highlight energy peaks on screen, but also to create quickly
a precise spectral report for the region of the spectrum that you need…and that
is just the beginning with the new Winplots! Notable feature enhancements to
the Winplots spectral reporting tool include: fill properties for identified,
unidentified, multiplet, and composite peaks; spectrum display in points, line,
or filled formats; peak information pop-ups; and manual or automatic scaling of
all axes. These features are available within GammaVision and WinPlots.
These new features allow you to define precisely the region of the spectrum that
you require — easily and quickly!
- Interactive Manual Calibration
When the time comes to import a spectrum for another format or you
need to fine tune the energy calibration of your spectrum, you need to get it
done without delay. The newly enhanced calibration features in GammaVision
include a Manual Energy Calibration dialog that offers greater flexibility in
fine tuning calibrations and ensuring compatibility with other spectrum
formats. The Channel and FWHM associated with each energy peak can now be
manually defined to match data pairs from other system spectra and precisely
duplicate their calibrations. Calibrations performed using the interactive and
automatic methods offered in earlier versions of GammaVision can also be
adjusted easily to meet specific needs.
- Fully-Embedded DataMaster Option
When you need to analyze spectra from various data formats, you need
to do quickly and easily — with as few steps as possible. The new GammaVision
includes an option for a fully-embedded application that makes reading and
writing in numerous spectral formats a snap!
DataMaster is a powerful spectrum conversion utility that is supported as an
Add-In for GammaVision. This program allows superior flexibility in converting
between a wide variety of spectrum formats for use in GammaVision and other
software products. Switching between different formats is now as simple as
opening or saving a file!
- True Coincidence Correction
to Reduce Effects of Cascade Summing
GammaVision includes a new algorithm for correction of cascade summing
(or True Coincidence Summing) gamma rays such as
those from Co-60, Cs-134, Eu-152, and hundreds of
other isotopes. Cascade summing results in loss of counts from photo peaks
which ultimately causes the under-reporting of
activities for the affected nuclides.
- ZDT™ Analysis with
Uncertainty Calculation
When used with the ORTEC DSPEC -PLUS
MCB, loss free counting correction using ORTEC's
Zero Dead Time algorithm can be enabled to correct every channel of the
spectrometer for counting losses due to system dead
time. This method is especially suited to applications such
as the analysis of rapidly decaying samples as in Neutron Activation
Analysis or "hot spots" as in real time monitoring
of effluents. GammaVision-32 also includes, for the first time anywhere,
the correct propagation of the counting uncertainties in the
ZDT-corrected spectrum (patent applied for).
- Calibration Wizard
A new calibration wizard walks the
operator through all steps to perform: Energy, Efficiency,
and True Coincidence Correction calibrations. The fully automated
wizard reduces the chances of data input errors
during the calibration process.
- New Analysis Engine
Optimized for Environmental Sample Counting
A new analysis engine, ENV32, has been added which enhances GammaVision-32’s
capabilities in analyzing complex environmental
samples. ENV32 allows the user to select a large library
with many potential nuclides and then uses a Mariscotti-type peak
search to identify, quantify, and report activities
for radioisotopes in the library. The new engine also includes directed fit
capabilities for singlets and multiplets.
- Presets for Counting
Users with DSPEC-PLUS MCBs can now take advantage of Multi-Nuclide MDA preset
count conditions in addition to all the other
available presets.
- Enhanced Support for
Nuclide Navigator III
Users of Nuclide Navigator III (Model C53-B32) chart of the nuclides software
can now directly use Nuclide Navigator libraries, in
Microsoft Access format, in GammaVision. You can also
select the Nuclide Navigator or GammaVision editor as the library
editor.
- Enhanced Source Certificate File
Editor
A fully graphical interface for creating and editing certificate files for
calibration sources.
- Built-in Support for
Future Hardware
New technology has been added so that GammaVision-32 will automatically
support new hardware (including the saving of
hardware parameters in the SPC file) without any change to
GammaVision itself. ORTEC’s unique, seamless integration of hardware
with the user interface remains fully intact.
- Expanded Dictionary of
GammaVision Job Commands
These commands have been added or enhanced in the Job File facility, to
increase the degree of automation achievable:
SAVE command includes an optional numeric identifier for support of MCBs that
have multiple spectrum capability (such as the
DSPEC-PLUS in ZDT Modes). Allows the operator to write JOB
files to save the spectrum in each of the memories automatically.
SAVE_CALIBRATION command added which allows the JOB file to save the current
energy and efficiency calibration to a new
calibration file (*.CLB).
- Direct Save/Recall of
*.SPE File Format
GammaVision-32 can save and recall spectral data in the ASCII SPE format
direct from the File menu (no translation into CHN
or SPC formats required).
- Improvements to the
Analysis Engines for Small Peaks
The peak analysis process uses the peak amplitude to reduce the
peak-analysis-width-region in order to reduce the
peak area uncertainty.
The directed fit process for small peaks has been improved.
The peak rejection flags (for bad shape) can be ignored. Small peaks
can often have bad shape
because of statistical fluctuations in the low counts per channel.
- New Analysis Engine
Optimized for Nuclear Power Plant Sample Counting
A new analysis engine, NPP32, has been added which specifically addresses the
needs of analyzing samples in nuclear power plants.
NPP32 was designed with the input from key nuclear power
counting room customers. In addition to a revised decision tree used
for determining the presence or absence of a
nuclide, a more detailed output report gives the users and reviewers
better information about how GammaVision qualifies the data.
- MCB Hardware Support
Fully Integrated Support for all ORTEC MCBs including the DSPEC-PLUS,
TRUMP-PCI, LANL M3CA, and Rossendorf MiniMCA-166.
