Fast Scanning Framework

1
Fast Scanning Framework

• Presented by G. Berruyer
• BLISS group

2
Why a framework for fast scanning ?

• Facilitate the integration of new hardware in an
  existing fast scanning process
• Make the use of fast scanning easy in order to
  implement it on the beamlines
• Facilitate the development of new fast scanning
  procedures

3
What is a fast scanning process ?

• This is a sequence
• In which a state is changing
• During this change, a decision is taken to tell
• Devices to take data.

4
Which objects can we extract from such a process
?
This is a sequence
SEQUENCER

• In which a state is changing

MOVER
SYNCHRONIZER
During this change, a decision is taken to tell
DATA READER
Devices to take data.
5
What is the SEQUENCER ?

• Definition
• Master of the fast scanning process.
• Characteristics
• Call the other objects method at the right time.
• In the real life
• Single Spec macros set merging zap, oscillation
  or other beamline specific macros

6
What is a MOVER ?

• Definition
• This is an object which changes the state of one
  or more beamline devices
• Characteristics
• Configuration Start/Stop parameters, trajectory
  
• It could define the start/stop conditions of the
  SYNCHRONIZER
• In the real life
• Motor(s) VPAP, VPAP/SMPAP/OPIOM, VSCANNER/OPIOM
• Time
• Temperature ramp.

7
What is a DATA READER ?

• Definition
• This is an object which is able to read data
  from beamline device(s).
• Characteristics
• Configuration
• Start/Stop condition
• Save
• In the real life
• Linux/OS9/MUSST Hook
• XMAP
• MUSST/MCA

8
What is a SYNCHRONIZER ?

• Definition
• Synchronize the reading of the DATA READER
  objects
• Characteristics
• Hardware links between SYNCHRONIZER and DATA
  READER
• Started by software or by hardware by the MOVER
  object
• In the real life
• VCT6
• OPIOM
• MUSST
• CCD camera

9
Implementation on the Beamline step 1

• Define what is available on your beamline as fast
  scanning framework objects (SYNCHRONISER, MOVER,
  DATA READER).
• Development of a tool providing
• List of existing instance of the fast scanning
  framework objects
• For each of them a dedicated configuration tool.

10
Implementation on the Beamline step 2

• Description of the fast scanning procedure using
  the available instance of objects defined before.
• Tool to generate the macro of a new fast scanning
  procedure
• which Synchronizer parameters
• which Mover(s) parameters
• which data reader(s) parameters

11
YA K

• Introduce the SYNCHRONIZER, MOVER and DATA READER
  objects in the ZAP sequencer
• Transform existing hook, motors manager macros
  set in their corresponding objects
• Merge this new SEQUENCER with other beamline
  specific sequencer
• Develop setup tool
• Develop procedure configuration tool
• Find a new name for this framework ZIP?
