Release Notes
8.1. Version 3.0.0
The main objective of the new release is a substantially improved detector calibration in parallel with a
considerably simplified detector usage. The user has no longer to worry about choosing suitable gain settings, this
task is now entirely handled by the detector. Depending on the energy threshold, the server continuously adjusts
the gain settings to ensure noiseless measurements with the smallest possible detector dead-time.
8.1.1. Modifications
Predefined settings are loaded by simply specifying the X-
ray energy in the form “-settings Cu”. No gain
has to be specified.
For optimal flatfield correction, the server has to be informed about the X-ray energy. It is recommended to
either use predefined settings or to set the energy threshold and the energy with help of the new “-
kthreshenergy” command. The energy can also be set with the new command “-energy”.
Improved precision of the rate correction.
Many new commands to retrieve the state of the system: “-get conttrig”, “-get cutoff”, “-get delafter”, “-get
delbef”, “ -get frames”, “-get gate”, “-get gates”, “-get inpol”, “-get module“ , “-get nmaxmodules”, “-get
outpol”, “-get trig”.
When increasing the number of active modules with the “-nmodules” command, all modules are set back
to default settings.
Multi-module systems can be controlled without looping over individual modules:
Commands retrieving module specific information return by default the values for all modules.
Commands setting module specific parameters affect by default all modules.
Instead of additional gain settings, extended threshold ranges can be requested by the customer.
Therefore the commands to set the energy or threshold only accept arguments within the supported
range. The upper and lower limits can be retrieved by “-get energymin”, “-get energymax”, “-get
kthreshmin”, “-get kthreshmax”.
New command “-get commandid” to retrieve a command identifier. This can be used to make sure that no
other clients changed the state of the system.
New command “-testpattern” for debugging purposes.
Legacy2 mode for backwards compatibility with version 2.
