Detector setup

mythen_put [id[:/-]]var arg

is used to configure the detector parameter var e.g. mythen_put 0:exptime 1 sets the exposure time to 1 s

help i

get help

config fname

reads the configuration file specified and sets the values

parameters fname

sets the detector parameters specified in the file

setup rootname

reads the files specfied (and that could be created by get setup) and resets the complete detector configuration including flatfield corrections, badchannels, trimbits etc.

hostname name

this is mandatory!!!! sets hostname (or IP adress)

online b

b can be 0 or 1 and sets the detector in offline/online state. Must be used to restore communication if some socket called failed because the detector was not connected.

status s

either start or stop

caldir path

Sets path of the calibration files

trimdir path

Sets path of the trim files

outdir path

directory to which the files will be written by default

fname name

filename to which the files will be written by default (to which file and position indexes will eventually be attached)

index i

start index of the files (automatically incremented by the acquisition functions)

nmod n

Sets number of detector modules

extsig:i mode

Sets usage of the external digital signal i. mode can be: off, gate_in_active_high, gate_in_active_low, trigger_in_rising_edge, trigger_in_falling_edge, ro_trigger_in_rising_edge, ro_trigger_in_falling_edge, gate_out_active_high, gate_out_active_low, trigger_out_rising_edge, trigger_out_falling_edge, ro_trigger_out_rising_edge, ro_trigger_out_falling_edge

timing

Sets the timing mode of the detector. Can be auto, gating (works only if at least one of the signals is configured as gate_in), trigger (works only if at least one of the signals is configured as trigger_in), ro_trigger (works only if at least one of the signals is configured as ro_trigger_in), triggered_gating (works only if one ofthe signals is configured as gate_in and one as trigger_in).

settings sett

Sets detector settings. Can be: standard fast highgain (depending on trheshold energy and maximum count rate: please refere to manual for limit values!);

threshold ev

Sets detector threshold in eV. Should be half of the beam energy. It is precise only if the detector is calibrated

cycles n

Sets the number of cycles (e.g. number of triggers)

probes n

Sets the number of probes to accumulate (max 3)

dr n

Sets the dynamic range - can be (1,) 4, 8,16 or 24 bits

flags mode

Sets the readout flags - can be none or storeinram

flatfield fname

Sets the flatfield file name - none disable flat field corrections

ratecorr t

Sets the rate corrections with dead time t ns (0 unsets, -1 uses default dead time for chosen settings

badchannels fname

Sets the badchannels file name - none disable bad channels corrections

angconv fname

Sets the angular conversion file name

globaloff o

sets the fixed angular offset of your encoder - should be almost constant!

fineoff o

sets a possible angular offset of your setup - should be small but can be senseful to modify

binsize s

sets the binning size of the angular conversion (otherwise defaults from the angualr conversion constants)

angdir i

sets the angular direction of the detector (i can be 1 or -1 - by default 1, channel 0 is smaller angle)

positions np (pos0 pos1...posnp)

Sets the number of positions at which the detector is moved during the acquisition and their values

startscript script

sets a script to be executed at the beginning of the measurements (e.g. open shutter). none unsets. Parameters will be parsed as script nrun=i par=spar where i is the run number and spar is the value of startscriptpar.

stopscript script

sets a script to be executed at the end of the measurement (e.g. close shutter). none unsets. Parameters will be parsed as script nrun=i par=spar where i is the run number and spar is the value of stopscriptpar.

startscriptpar spar

sets a parameter passed to the start script as string with the syntax par=spar. Its meaning must be interpreted inside the script!

stopscriptpar spar

sets a parameter passed to the start script as string with the syntax par=spar. Its meaning must be interpreted inside the script!

scan0script script

Sets a scan script to be executed at higher level. Script can be none (unset), threshold (change threshold DAC values for all modules), energy (change energy threshold DAC values using calibration for each module), trimbits (change trimbits for all channels) or any script (e.g changing temperature or moving sample) which will be called with the syntax script nrun=i fn=fname var=val par=spar where i is the file index, fname is the file name val is the current value of the scan variable and spar is the value of the scan parameter

scan1script script

Sets a scan script to be executed at lower level. Script can be none (unset), threshold (change threshold DAC values for all modules), energy (change energy threshold DAC values using calibration for each module), trimbits (change trimbits for all channels) or any script (e.g changing temperature or moving sample) which will be called with the syntax script nrun=i fn=fname var=val par=spar where i is the file index, fname is the file name val is the current value of the scan variable and spar is the value of the scan parameter

scan0par spar

sets the scan parameter to be passed to scan0script as a string with syntax par=spar. Its meaning has to be interpreted insode the script!

scan1par spar

sets the scan parameter to be passed to scan1script as a string with syntax par=spar. Its meaning has to be interpreted insode the script!

scan0prec i

sets the precision of the scan variable in order to properly generate the file names for scan0
