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

• “Do it yourself! - Scan Tools

ADAQA Applications



•General purpose camera display and analysis 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

Specialised Scan Tools



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

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)

Helge Brands

Current situation

•WHLA: each Camera-IOC has 1GB/s (enough for 10Hz) •3 PCO Edge in operation + 1 PCO Edge in preperation

•upload to AFS max 50MB/s

•software is ready for 100Hz

•needed network speed 10GBit/s for 100 Hz

•other GIGE cameras can be used too

•additional compute nodes should be planned

•storage policies are needed
