Documentation:
The MAR345 scanner provides a X-ray detection area from 180 to 345 mm with two possible pixel sizes 100 and 150 micro-meter. This scanner is using a unique image-plate that is erased after each exposure-read-out cycle. This is why the mar is used as detector and not as a offline scanner. Read-out cycles range from 108 to 34 (!!!) seconds, depending on pixel size and scanned plate diameter. This is about 3 times faster than other scanners and actually comes close to the performance of CCD-detectors. a TACO device server named MarScan345ds is running on the MAR computer and controls the scanner. OVERVIEW These user macros allow full control of the scanner for doing single scan, enabling spec scan with the mar like pseudo-counter or starting a data collection with spindle/shutter synchronisation. DEPENDENCIES The file(s) marcollect.mac, ccd.mac and oscil.mac have to be read in | ||||||
Macros:
Usage: marsetup [ccd device number] Has to be called first with ccd-device-number as defined into the spec configuration. marnewfile Usage: marnewfile Set new file parameters. marimagepar Usage: marimagepar Set image parameters, detector distance and wavelength marcollect Usage: marcollect ["filename prefix"] ["frames number"] ["passes number"] ["oscillation range"] ["oscillation overlap"] ["exposure time"] ["starting position"] ["image directory"] ["erase first"] Performs the data collection. will acquire [frames number] images into the ["image directory"] directory with the file names ["filename prefix"]_$$ (where $$ is from [starting frame number] to [starting frame number]+[frames number]. The first position will be [starting position], the angle oscillation for each frame is [oscillation range] and there will be [passes number] passes for each frame in [exposure time] seconds. | ||||||
| Internal Macros: | ||||||
Usage: mar_imagepar() mar_filepar Usage: mar_filepar() internal function that really set the new file parameters. return -1 if the esrf_io failed mar_getfilename Usage: mar_getfilename() internal function that reset the current filename setting return -1 if the esrf_io failed marshow Usage: marshow mar_getvals Usage: mar_getvals mar_head Usage: mar_head mar_loop_frames Usage: mar_loop_frames() mar_dataloop Usage: mar_dataloop | ||||||
