XiCLone is a premium option for MonoCL3 which provides spectrum imaging
to complement standard functionality. This premium option is based on
MonoCL3 with DigiScanCL beam control and incorporates ParaCL and SEM Base
and CL specific Spectrum Imaging software plug-ins. With a choice of ParaCL
CCD or InGaAs array cameras, XiCLone spectrum imaging can cover a range
of wavelengths from 200nm to 1700nm.
With ParaCL, users gain from the power of recording a spectrum in a matter
or seconds, or less. With XiCLone, the CL technique makes a quantum leap
as one spectrum is recorded for every pixel in a linescan or map. DigitalMicrograph
software for XiCLone brings power and simplicity to acquiring and handling
large data sets.
With an appropriate Parallel CL acquisition identified, spectrum image
acquisition is a simple matter of defining a region of interest on a survey
image, plus a pixel density. The beam position and spectrum are shown
live as the spectrum imaging builds up. Furthermore the user can interrogate
the results live without waiting for completion.
For long experiments or those performed at high magnification, a drift
correction procedure is easy to program based on a user identified marker
position.
Extracting useful data from large 3D data sets is a key post-processing
step that can be performed on the same computer, or off-line on an office
computer. Spectrum imaging analysis tools include:
1. Integrations from specific areas
2. Overlay and manipulation of multiple extractions
3. Bandpass extraction of chosen width using a slice tool
4. Conversion to eV data sets
5. Movie mode of sequential bandpasses
6. Volume remapping tools, for condensing or extracting unwanted planes.
7. Shoulder peak extraction tools based on linear or polynomial fitting
of parent peaks
8. NLLS Gaussian Peak Shift, Width, Amplitude and Residual Signal extraction
tools. Can work with multiple peaks with optional constraints and choice
of simultaneous or sequential processing
9. MLLS fit coefficient maps for multiple user identified reference spectral
fingerprints. These can be standards taken from other data sets, of chosen
as specific feature from the parent data set
10. Show true colour. The software calculates and displays the colour
the eye would see assuming the spectral coverage is appropriate
11. Export functions.
EDSSI
EDSSI is an advanced Gatan software package which enables EDS (Energy
Dispersive X ray) acquisition and analysis.
This option exists as a standalone product for users with DigiScan, or
as a complementary option for XiCLone. In this case Multi-Signal Spectrum
Imaging can be performed with the CL and EDS data sets acquired in tandem
using the same beam control platform. Raw EDS data is acquired from a
modern 3rd party EDS detector and pulse processor, (usually over an Ethernet
connection). Please check with Gatan regarding compatibility and note
that full functionality can depend on IT or 3rd party software considerations
outside of Gatan’s control. For some platforms, an additional licence
is required from the EDS manufacturer to enable this communication between
the Gatan and EDS operating PCs.

acquired CL and EDS spectrum images from geological specimen.
In addition to the data extraction tools useful for CL, powerful quantitative
elemental extraction tools are included.
Once complex 3D data sets are reduced to a series of 2D specific elements
or phases, bivariate or trivariate histrograms can be performed .
