parameters for making a
measurement are set.
Setup parameters are:
-Material Selection
-Collimator Selection
-Bracket Selection
-Type of Radiation
-Time (per Angle)
-Measurement Type
-Measurement Description
-Position Queue (Ψ Tilt
angles to be measured)
Material Selection

All of the materials
that TEC has
information on are
stored in a Materials
Library file in the
software. Materials
can be added,
edited, or deleted in
this selection tab.
Material Selection - Add


Materials can be
added in this
selection if the
parameters are
known.
If needed, TEC can
assist with this
information.
Materials Selection - Edit

Any information that
needs to be changed
for a material is
entered here.
Collimator Selection

The collimator size is
selected according
to type of surface
(flat or curved).
- Flat surface generally
uses a round collimator.
- Curved surface generally
uses a rectangular
collimator.
Collimator Selection - Edit



Collimator selection
allows you to
rename collimators
or add different
sizes of collimators.
(Round sizes in 1,2,3,4,
and 5mm.)
(Rectangular sizes are .5,
1.0,1.5,2.0, and 3 X 5mm)
Bracket Selection


The bracket that is
recommended for
the material being
measured is
automatically
determined when
the material is
selected.
It can be changed
manually to
accommodate other
diffraction peaks.
Bracket Selection - Add

If a bracket needs to
be added it can be
done with the ADD
option.
Detector Orientation Option

This option is to let
the software know
what orientation the
detector is in. The
two options are Ω
and Ψ.
Detector Orientation

The TEC 4000 is
capable of Ψ and Ω
Detector Orientations.
The orientations are
limited to size and
geometry (shape) of
the part to be
measured. Almost
every part can be
measured using one of
the detector
orientations.
Ψ (PSI)
Orientation
Ω (Omega)
Orientation
Detector Parameters

The detector
parameters are
entered during a
detector calibration.
Once set, they do
not need to be
adjusted until the
detector or detector
electronics is
replaced.
X-Ray Tube Status

The type of
radiation being used
is displayed here
along with the
power settings.
Measurement Description

generated to let the
user know what
events have taken
place while the
software is active.
It can be used in
troubleshooting the
system for hardware
faults.
Diagnostics - Exposure Log Tab


This log is generated
to let the user know
how long the X-rays
where energized.
It logs the time that
the x-rays were
turned on and off
while the system is
being operated.
Diagnostics - Error Log Tab

This log is generated
when the system
detects an error that
the system
encounters.
Diagnostics - Safety System Tab


The Safety features
of this system are
monitored here.
If the system
encounters a
problem, it will be
displayed here and
the system will
display a safety
system error
message and will not
proceed with a
measurement.
Display During Data Acquisition

A display of the spectra
will be displayed during
Data Acquisition in real
time screen updates
once the measurement
has been started.
After Data Acquisition

After the data
acquisition is
finished, the
corrected spectra
is displayed and
the launch analysis
button will start the
SaraTEC Analysis
software and will
display the results.
Benefits of using the
TEC 4000
Fast results allow production, statistical, and process
control to improve quality and to reduce costs.
 System can be easily and quickly reconfigured to analyze
a wide variety of materials.
 Nondestructive testing possible since parts often do not
require sectioning.
 Stress vs. Depth Profile is easily performed to evaluate
peening intensity.
