Documentation:
This macro set provides the possibility to execute continuous scans with one or two motors. During these scans peaks can be searched. OVERVIEW The following macros are provided: EXAMPLE ATTENTION Before the first use of cscan or cmesh, you have to execute the macros plotconfig, plotselect and cscansetup. | ||||||
Macros:
Usage: cscan <motor> <start> <stop> <speed> [sleeptime] Scans motor continuously from start to stop. During the scan the moving speed is set to speed. Is 0 given as the moving speed, the actual moving speed isn't changed. If the parameter sleeptime isn't specified, the sleeptime is 0. It is possible to search for peaks during the scan (see cscansetup). c2scan Usage: c2scan <m1> <s1> <f1> <speed1> <m2> <s2> <f2> <speed2> [sleeptime] As cscan but two motors are scanned continously. If one of the moving speeds is 0, the second one is calculated that manner, that both motors arrive at the same time. If both are omitted the current moving speeds are kept. If the parameter sleeptime isn't specified, the sleeptime is 0. It is possible to search for peaks during the scan (see cscansetup). cmesh Usage: cmesh <m1> <s1> <f1> <speed> <m2> <s2> <f2> <intervals> [sleeptime] Traces out a grid using the motors m1 and m2. The first motor scans continuously with the moving speed speed from s1 to e1 while the second one scans from s2 to f2 using the specified number of intervals: The scan of m1 is done at each point scanned by m2. That is, the first motor scan is nested within the second motor scan. If the parameter sleeptime isn't specified, the sleeptime is 0. It is possible to to search for peaks during the scan (see cscansetup). cscansetup Usage: cscansetup Defines options for the macros cscan and cmesh. You will be asked the following questions: Do you want to save (NO)?It is possible to save the results. Do you want to plot (YES)?You can plot the results.
Plotting (Only for cmesh)
1 : for every slice
2 : for the whole scan (2)?
If you chose the first option one slice is plotted after the other, otherwise
all slices are plotted in the same graph.
Count unit for plotting and peaksearch:
1: Counts
2: Counts/s
3: Counts/Monitor counts (2)?
You can specify if you want to plot Counts, Counts/s or Counts/Monitor counts.
This selection is also used for the peaksearch.
Peaksearch
0 : No peaksearch
1 : Maximal counts/s bigger than threshold (1)?
Threshold in counts/s (0)?
You can execute a peaksearch over the scan results, in this case you have to
give the minimal value (threshold) for a peak.

Usage: _cscan_check Parameter check for the macros cscan, c2scan and cmesh _cscan_init Usage: _cscan_init Initialisations for the macros cscan and c2scan _cmesh_init Usage: _cmesh_init Initialisations for the macro cmesh _cscan_init_group1 Usage: _cscan_init_group1 Initialisation of the group used for plotting and peaksearching: Tests if the group has enough points to plot the probably needed number of points. If more points are needed than available, a data reduction factor is calculated (e.g. only every second point is taken into account for plotting and peaksearching). This data reduction doesn't concern the data which is saved. Every data point is saved. _cscan_end Usage: _cscan_end Cleanup macro which is called after a normal end of the macros cscan und cmesh. _cscan_cleanup Usage: _cscan_cleanup Cleanup macro which is called in the case of the abort of cscan or cmesh with Ctrl-C: Closes the datafile and resets the old speed. _cscan_set_speed Usage: _cscan_set_speed Sets the new speed for the continuous scan. _cscan_unset_speed Usage: _cscan_unset_speed Resets the old speed. _cscan Usage: _cscan <motor> <to> Execution of the continuous scan of motor motor to the position to. _cmesh Usage: _cmesh Execution of the 2d grid scan with one motor moving continuously. _cscan_get_first_point Usage: _cscan_get_first_point Gets the first point (only the motor position) _cscan_get_point Usage: _cscan_get_point Gets data of one point in the data group. _cscan_peak1 Usage: _cscan_peak1 Peaksearch for one slice. _cscan_display_peak Usage: _cscan_display_peak <peak> <motorpos at max> Displays a peak (in the plot window and in spec). _cscan_display_no_peak Usage: _cscan_display_no_peak Displays that there is no peak (in the plot window and in spec). _cscan_plot_point Usage: _cscan_plot_point Plots one point. _cscan_save_header Usage: _cscan_save_header Writes the scan header to the data file. _cscan_save_point Usage: _cscan_save_point Writes the scan data of one point to the data file. _reset_CSC_LAST_CNT Usage: _reset_CSC_LAST_CNT | ||||||
