Special Commands for the Reflectometer (AMOR)
There are some special command initializations for the reflectometer AMOR.
These commands are most likely not portable to other instruments because
they encompass the special geometry at AMOR and the AMOR development has
not fully matured. The following initialization commands are available:
- MakeAmor2T name da
- This creates a virtual two theta motor for the reflectometer
AMOR. The two parameters are the name of the object in SICS and a
Tcl-array with configuration parameters. The needed elements of this
array are:
- mom
- The monochromator omega motor.
- som
- The sample omega motor.
- coz
- The height movement of the detector.
- cox
- The movement of the detector along the optical bench.
- stz
- The height movement of the sample connected to the omega circle.
- soz
- The height movement of the sample table.
- d4b
- The motor moving the whole diaphragm 4 up.
- d5b
- The motor moving the whole diaphragm 5 up.
- com
- The omega mevement of the detector.
An example:
set a2t(mom) mom
set a2t(som) som
set a2t(coz) coz
set a2t(cox) cox
set a2t(stz) stz
set a2t(soz) soz
set a2t(d4b) d4b
set a2t(d5b) d5b
set a2t(com) com
MakeAmor2T a2t a2t
creates a virtual AMOR two theta motor with the name a2t.
- MakeStoreAmor hm
- Creates an object for writing reflectometer data files. The name
of the command is storeamor. The parameter hm denotes the histogram
memory object.
- MakeAmorStatus name scan hm
- This creates a helper object for the reflectometer status display
with name name. This object performs some operations on behalf of the
status display for the reflectometer AMOR. The parameter scan denotes
the name of the scan object. The parameter hm the name of the
histogram memory object.
AMOR Status Display Commands
MakeAmorStatus creates a SICS command which is used by the AMOR status
display for displaying proceesed data, especially in TOF-mode. This module
provides the following commands:
- amorstatus interest
- This registers this connection for receiving automatic
notifications. Automatic notifications send are:
- SCANSTART
- At scan start a message ScanClear is sent followed by the
uuencoded new x-axis for the plot.
- SCANPOINT
- At each scan point the arrays of counts in both detector are sent
in uuencoded form labelled arrow_spinupup and arrow_spinuplo.
- COUNTSTART
- The start of counting on the histogram memory. Send a message
TOFClear and then the uuencoded time binning labelled
arrow_time.
- FILELOADED
- activated each time user defined model data is loaded into the
SICS server. This data gets send as arrow_name in uuencoded form. Both
x- and y-axis are sent in floating point.
Please note that floating point data is transformed to fixed point by
multiplication of 65653 before transfer. The first number in each
uuencoded message is an integer describing the length of the data. In
case of double data such as fileloaded the y-data follows immediatetly
after the x-data. Also the appropriate data is automatically sent after
the interest command.
- amorstatus collapse
- sums all counts in all detectors in time and sends the data back
as an uuencoded image. The first two numbers in the message define the
dimensions of the data.
- amorstatus sample name x1 x2 y1 y2
- Sums the detector counts on an area defined by the rectangle x1,
x2, y1, y2. The length of this is the time binning. The data is sent
back in uuencoded form labelled arrow_name.
- amorstatus clear
- Clears all user loaded data.
- amorstatus load filename scale
- loads user defined data for distribution to the status display
clients. The y data is scaled according to the scale factor provided.
- amorstatus projectytof
- Returns a UUencoded 2D array of y against TOF.
