CCD
Range
In a CCD Range experiment, the spectrometer is set to acquire data throughout a
wavelength range which is selected by the end-user via SynerJY software. When the
experiment is run, the spectrometer’s grating rotates to collect data in sections, with each
section representing a different wavelength range. There is a small overlap at the edges of
each section. Once all data is collected by the detector, the individual sections are
combined to produce a single spectrum.
Required Parameters:
Areas, X-Binning, Integration Time, Accumulations, Gain and
ADC Speed.
Triggering
External Triggers may be used to synchronize experiments. Triggers can be implemented
to start an experiment sequence or can be used on each individual accumulation. Please
refer to Chapter 5 for a more detailed discussion on triggering with the Synapse CCD
detection system.
Acquisition Mode Parameters
•
Areas –
definition of the active sections of the CCD detector. Signals that
encounter sections of the CCD that are not part of an active area are not
recorded. Once an area is specified, the area definitions refer to the number of
areas and the size of the areas.
•
X Binning
–
number of columns combined to form a single data point. By
combining columns, a greater signal level can be detected; however, this results
in a decrease in resolution.
•
Y Binning
– number of rows combined to form a single data point. By
combining rows, a greater signal level can be detected; however, this results in a
decrease in resolution.
•
Integration Time
– amount of time the CCD is exposed to light and acquires
data.
•
Accumulations
– number of repetitions for which the detector collects data and
averages the results to obtain a better signal-to-noise ratio.
•
Gain
–
equates the least significant bit (LSB) of the Synapse 16-bit ADC
architecture to an appropriate electron level (see Chapter 8: Gain Selections).
Note
:
CCD Range mode experiments are only
supported under SynerJY software. For more
information, please refer to the SynerJY software
manual.
