"""
Implementation for falcon at PHOENIX, derived from
implementation on csaxs (file falcon_csaxs.py)
Differences to implement
1) we consider EPICS initialization as standard implementaion,
so no reinitialization when bec device is initrialized
2) use mca spectra as base mode of operation
3) make easy switching between mca spectra an mca mapping
4) fix defiend relation bwetween variables and names used here for example
aquiring is currently called 'state' --> should be renamed to aquiring
Currently state = Cpt(EpicsSignal, "Acquiring")
should be acquiring = Cpt(EpicsSignal, "Acquiring")
ISSUES TIMEOUTS
Timeouts occur and seem to be not reproducible
See scilog documentation
Locations on timeouts are :
def arm_aquisition
raise FalconTimeoutError(
f"Failed to arm the acquisition. Detector state {signal_conditions[0][0]}"
)
CHANGES LOG and
System as taken from cSAXS some times works for one element need about 7 second
