Similar to U235, but optimized for HPGe detectors. Only one intensity calibration measurement is<br />
necessary.<br />
3.5.2 LENG<br />
This program supports semi-automated active length measurement (HM-4) using a miniature NaI<br />
or CdZnTe detector.<br />
3.5.3 RATE<br />
This program supports measurements of count rates with any radiation detector (HPGe, NaI,<br />
CdTe, CdZnTe and neutron counters). In the most convenient mode of operation only the menu<br />
button "measurement" needs to be "pressed" to start a measurement and showing the count rates<br />
in form of a LCD display and a bar graph.<br />
3.6 Windows software<br />
3.6.1 The program Win<strong>MCA</strong><br />
The program Win<strong>MCA</strong> has mostly the same features as <strong>MCA</strong>, but for a Windows 95<br />
environment. It is written under Visual Basic in 32 bit code.<br />
To install, copy all files to a temporary directory and then start setup.exe or install from<br />
the floppy disks.<br />
The main differences to DOS <strong>MCA</strong> are:<br />
• supports saving of spectral data in *.tka format (only ASCII string of channel data, e.g.<br />
for use in a spread sheet)<br />
• supports saving of report files (no spectral data, but all ROI information, begin, end,<br />
centroid, FWHM, FWTM, Integral, Area, Area error).<br />
• Open/Save options can be accessed via File/Preferences<br />
• Also some more options concerning display (graph style, color) and general program<br />
options are found<br />
• In MCS operation mode, different firmware / software acquisition modes can be found,<br />
some of them offering absolute continuous measurements, avoiding gaps for file<br />
saving. So, up to 65536 MCS spectra with up to 4096 channels can be measured in<br />
series, which results in a theoretical maximum of 256 M channels in total.<br />
• MCS mode offers the possibility to measure simultaneous MCS and amplitude<br />
spectrum.<br />
• Some bugs concerning the active groups, strip, compare and move have been fixed.<br />
• PZC offers now also an automatic option.<br />
• SCANDU option<br />
• CdTe detector test option.<br />
• Supports using signals at the HV inhibit connector for triggering<br />
3.6.2 WinSPEC-I (for Inspectors)<br />
WinSPEC-I was developed for the IAEA. It is derived from Win<strong>MCA</strong>. It is used for spectrum<br />
measurements (equivalent to SPEC DOS programs, but with more advanced features; as e.g.,<br />
integration of MGAU for U enrichment measurements.<br />
Special attention was spent to the design of the GUI to make its use intuitive and easy.<br />
3.6.3 WinSPEC-A (for Automation)<br />
WinSPEC-A is an extended variant of WinSPEC-I. It was designed for unattended<br />
measurements.<br />
Special features of this variant are:<br />
