The scan syntax is like on TASMAD.
Arguments of SC:
- any driveable variable, and its center value
- any step (D immediately followed by the variable name)
- NP followed by the number of points (note: if NP is even,
the scan center is between the two points in the middle).
- MN or TI followed by the monitor or time preset value
The presence of 4 argument parts is mandatory, but the order of
the parts is not relevant. For every step variable, the corresponding
center value must be given.
If no step is given for a center variable, a step 0 is used.
Special cases are the variables QH and Q3 , and their
corresonding steps DQH and DQ3 which have 3 or 4 values.
- energy scan (the following two beeing equivalent))
> SC QH 1 0 0 0 DQH 0 0 0 0.01 NP 5 MN 1000
> SC QH 1 0 0 EN 0 DEN 0.01 NP 5 MN 1000
- q scan (the following two beeing equivalent))
> SC QH 1 0 0 0 DQH 0 0.01 0 0 NP 5 MN 1000
> SC QH 1 0 0 0 DQH 0 0.01 0 NP 5 MN 1000
- motor scan with time preset
> SC A3 25 A4 50 DA3 0.1 DA4 0.2 NP 11 ti 1
The new UB matrix system allows to drive Q out of plane within the limits of the sample goniometers sgu and sgl. If there is a sample
environment device on the sample table which may not be tilted, please restrict the movement of motors sgu and sgl through software limits.
> POLSCAN script "scan variables and steps" NP np MN mn
The script contains all what has to be done at one scan point. Its exact syntax
is still open.
