What Came Before…(my personal collection of accelerator data acquisition)

>TESLA Test Facility at DESY, Hamburg>Access to accelerator process variables from MATLAB, C++ (read/write)>Easy to write data acquisition software, scan parameters, record variables…>Data stored in .MAT, ASCII & ROOT files>No common data format>Experts required to set up scan, analyze data…

>SLAC LINAC at Stanford, California>VAX-based control system>Scan software to determine the dependency of a variable on a parameter>On-line display & fits>Writes MATLAB 4 files for further analysis

2


Design Goals>Have a universal scan and data acquisition software

>Well-tested scan core>Universal GUI to set up scan easily>Specialized GUIs for easy access for regularly performed scans

>Error checking and treatment

>Common HDF5-based file format for easy access from any data analysis code

>Automatic generation of logbook entries

>Link to auxiliary information on accelerator configuration

>Synchronized data acquisition

Data File Format>Hierarchical format to store Instruments>Based on HDF5>Readable from Matlab, Root, Mathematica…

Accelerator Data AcquisitionMany accelerator measurements consist of the following tasks:

>Control 0…N actuators>Acquire 1…M measurements>Analyze data

Important features>On-line analysis>Reasonable error handling>Robust code for use by other persons than the programmer

5


ADAQA Layers>ADAQA consists of several

separate building blocks>Applications, written by different

programmers, make use of the same data acquisition code

>Instruments gather connected devices

>Logbook>Common data storage format>Online model*>Device information server*>Synchronized data acquisition

* ongoing work, not yet ready for prime time

6


ADAQA Layers >Tree-like structure:

>Many devices (roots)>One data acquisition core (trunk)>Many applications (branches)

>Building blocks can be exchanged

Synchronized Data Acquisition>All VME crates for diagnostics are equipped

with an Event Receiver>Connected with a star topology network to

the Event Generator>Supported for:

>BPMs, Bunching monitor, RF, …>Ongoing work:

>Laser shutter, oscilloscopes, cameras

ADAQA Applications



• General purpose camera display andanalysis tool

• In every day use for different kinds of cameras and screen monitors

General Purpose Scan Tool



the future…



• Scans can be stored in Template files• The last scan is always stored as template

–“Repeat Last Scan…”-Button• Data files are scan templates as well

–All scans can be exactly repeated

• Templates can handed over to the scan tool at startup–example: extracted charge vs. gun phase scan

Scan Templates



Specialised Scan Tools



Automatised logbook entries



• General and specialised scan tools are possible with ADAQA–a wide variety of tools is available

• Common data format• Templates

–data files are templates – for all tools• Actions

–e.g. automatic screen insertion or background subtraction• Analysis functions

• Automatic logbook entries

Scan Tools Summary

instrument{1} = LoadInstrumentDefinition('SwissFEL_Meeting_Demo');

Setup.Function = 'scan'; % define scan setupSetup.Repeat = 10; % “shots” per scan step

Image based measurements: today

Problems:• available buffers on IOC are not used• „lost“ of measured data• high frequencies can‘t be reached• high CPU load on workstations

Why?

•less radiation•higher recording speed (10Hz/100Hz)•independent of the workstation (CPU and memory)•system is similar to SLS (Tomcat, in operation, 1* PCO Edge)
