MOSCA MCA Controller¶
Configuration¶
YAML configuration for a MOSCA MCA controller
- name: mca_sim
class: McaSimulator
module: mosca.simulator
plugin: generic
tango_name: id00/mosca/simulator
roi_correction_formula: roi / (1-trigger_livetime/realtime) / iodet #(optional)
external_counters: #(optional)
iodet: $diode1 #(optional)
# Valid variables for the 'roi_correction_formula' are:
# - 'roi'
# - a stat label (ex: 'icr', 'ocr', 'deadtime', ...)
# - an external_counter tag as declared below 'external_counters' (ex: 'iodet')
Usage¶
BLISS [10]: fx
Out [10]: === MCA controller: id42/falconx/fx ===
detector name:
detector model: XIA FalconX
channels number: 2
spectrum size: 4096
trigger mode: SOFTWARE
preset mode: REALTIME
preset value: 1.0 s
detector mode: MCA
refresh rate: 0.1000 s
configuration file: c:\blissadm\falconx\config\id42/20241210-ID12FalconX2-MR-8keV_Iron_spec.ini
Counting for 120 ms with a 2-channels FalconX. By default, 8 statistics counters ares displayed.

Statistics counters can be individually selected:
BLISS [19]: ct(0.120, fx.counters.events)
ct: state elapsed
DONE 0s

Configuration file¶
A new configuration file can be loaded:
* by setting the configuration_file property
* using load_configuration(<filename>) method
* using load_configuration() to select file in a list

ROIs¶
Regions of interest can be set with:
set()methodload_rois_from_file()methodedit_rois()method to define them graphically using Flint
Using rois.set() method.
BLISS [1]: fx.rois
Out [1]: name channel roi
------------------------
BLISS [2]: fx.rois.set("AuLa", (654, 785))
BLISS [3]: fx.rois
Out [3]: name channel roi
--------------------------
AuLa all (654, 785)
ROIs corrections¶
ROIs can be corrected using a calculation formula and statics counters.
Example for dead time correction:
roi_correction_formula: roi / (1-trigger_livetime/realtime)
See https://gitlab.esrf.fr/-/snippets/249 for calculation details.
