Important SPEC commands available at ID2:

SAXS/WAXS (EH2):

Shutter commands
sc to close the safety beam shutter
so to open the safety beam shutter
fson to activate fast beam shutter for scanning and counting
fsoff to disable
 fast beam shutter for scanning and counting
fsshow to show triggering of fast shutter
bvcl to close the big valve (V11)
bvop to open the big valve (V11)

Movement commands
wut to see motor user values
umv <motor> <position> to move a motor to the desired absolute position
umvr <motor> <step> to move a motor to a relative position
samplescan <motor> <from> <to> <steps> <time> to align sample (closes big valve)
Note: to continue taking CCD images answer 'yes' or use bvop

Use of CCD detectors
ccdnewfile to set directory and filename for image saving
ccdexpinfo to set header information for NEXT exposure
ccdactive to set CCD active/inactive
ccdbin <binning1> <binning2> to set binning of CCD camera
cm <camera> to set the online image correction parameters
click here for more details
ccdtfg to pause before a CCD acquisition



ccddisp to open the image display (if it was lost)
cao to open the newplot display (if it was lost)



ccdstop to reconfigure the application (if you stop the acquisition by "CTRL C")



ccdexpose <exptime> <save(0/1)> <ndark> <"title"> to take a single image
ccdcorsave or cs to save the corrected image (if necessary)
ccdtrans <motor> <from> <to> <steps> <time> <sleep><"title"> <ndark> <save(0/1)> to scan on a sample motor and take images at each scan step (saving after each step)
ccdframes <frames> <exptime> <clock> <"title"> <ndark> <save(0/1)> to take multiple frames with lower time resolution (> 10s, depending on binning - saving after each frame)
Note: use application EXPTIME to change exposure time or abort:
exptimeset <exptime>
exptimeset -1 (to abort ccdframes safely)
ccdmulti <frames> <deadtime0> <deadtime1> <exptime> <save(0/1)> <ndark> <"title"> to take multiple images (saving after the last frame)
deadtime0 before first exposure
deadtime1 between exposures depending on binnig:

ccddark <exptime> <frames> to take only dark images (in case of ccdmulti/ccdkin with 0 dark images)
ccdfilm to view multiple images taken with ccdmulti
ccdcorsave or cs to save the corrected image (if necessary)



ccdkin <frames1> <frames2> <frames3> <deadtime0> <deadtime1> <deadtime2> <deadtime3> <exptime> <save(0/1)> <ndark> <"title"> to take multiple images in three time groups (saving after the last frame):
frames1-3 number of frames in groups
deadtime0 before first exposure
deadtime1-3 between the frames of each group
(see ccdmulti for minimum times)
ccdcorsave or cs to save the corrected image (if necessary)



ldo to list all detector position files
ddo <det-file> to import detector position file



att <number of attenuators> to insert / extract Al attenuators (attenuation factor about 15 per foil)
att 0 to remove - not recommended for SAXS exposures
use ATT application on SAXS6 to insert more attenuators



open() to show used log files
disablemotormenu to enable / disable motors
disablecountermenu to enable / disable counters

USAXS (EH1):
so to open the safety beam shutter
sc to close the safety beam shutter



bhstart to begin experiment (close shutter, move out fast shutter, move monochromator in beam, absorber att 5)
bhtune <att to align mono> <time> to do automatic alignment of crystals (typical bhtune 0 1 -- use bhtune 2 1 to protect sample)
NOTE: make sure that you have beam in EH1 !!
newfile to set new name for *.spec file
and for bhscan files
bhstop to end experiment (close shutter, move in fast shutter, move monochromator out of beam, no absorber)



att <number of attenuators> to insert / extract Al attenuators (attenuation factor about 15 per foil)
att 0 to remove
bhmon to activate monitor (APDB) - for counters and plotselect
bhdet to activate detector (APDA) - for counters and plotselect
dscan, ascan <motor> <from> <to> <steps> <time> to scan motor - use bhmon or bhdet to select detector
cen to move to center of mass of last scan
pic to move to maximum of last scan
where to plot current motor position
wut to plot motor position (user only)



bhscan 1.3 <end> <steps> <time> <"title"> to measure rocking curve -- typical command:
bhscan 1.3 3.5 110 1 "test"
bhscan 1.3 4 135 1 "test"
