4. PreExperiment Data Collector
FEATURES:
• Customizable on-the-fly view forms defined in YAML
• Different policies are applicable to the view forms: web, web-readonly, tango
• Supports different validations: number, double, string, text, required
• Provides tango access to data
• Offline clients

5. Status Server
FEATURES:
• Forms continuous timeline of the experiment
• Simple configuration, defined in XML
• Values can be obtained through event or polling mechanism
• Different interpolation strategies: last, nearest and linear

6. Mobile Status Server Client
• Monitor the ongoing experiment from a mobile device
• Review experiment when device is offline
• Configure easily for a variety of different instruments

10. Integrating everything together

11. Data transfer between Tango servers.
Apache Camel Integration.

12. Data transfer between Tango servers.
Apache Camel Integration.
Apache Camel is a rule-based routing and
mediation engine that provides a Java object-
based implementation of the Enterprise
Integration Patterns

13. Apache Camel routes.
Camel Integration Tango API library:
https://bitbucket.org/Ingvord/camel-tango
Works with pipes (events, polling, single acquisition)

14. Control Environment [IDL Scripts]

15. Web monitoring and control. Web Jive.

Browse Tango devices

Add/remove devices

Quick test new devices

Quick monitor existing devices

16. Why do we need a new Jive?

Narrow down UI to actually used features:
– Remove unused settings and configurations
– Simplified device context menu
– Simplified server wizard

Benefit from web interface: wide screen; reorganize views

Lightweight and fast
Jive is like a swiss army knife...
80% of the time
we need 20% of its features
Our own new Jive:
To fulfil Tango V10 FR6 – generic web application

17. Web Jive 2.0 (current release version 0.1)

Dynamic Device tree (devices are loaded on demand)

Test device panel

Editable Device tab (Info, Properties, Attributes config,
Events etc)

Interactive Monitoring tab, aka embedded ATK Panel

Simplified Server wizard

Log console

20. OpenCL real-time reconstruction server
A Tango server that performs a reconstruction in parallel to the experiment.
FEAUTURES:
•Based on KIT’s UFO project.
•Main goal: to give users close to real time reconstruction
•Deal with up to 1000 frames/s (1 frame = 2K x 2K)

21. Hardware triggering driven experiment.

23. Packaging
Every component is an independent single
Executable jar file!
Dedicated project holds all configuration
files.

24. Packaging

25. ●
Beamline scientist friendly environment
●
Fully automitazed and ease deployment
●
Integration with DESY computer center
●
Works stable for 3 months without any support
●
Opensource, available @bitbucket.org/hzgwpn

Consider the following example:
DeviceProxy proxy = new DeviceProxy("some-device");
DeviceAttribute attribute = proxy.read_attribute("some-attribute");
if(result.hasFailed()){
throw new Exception("Can not read attribute.");
}
int dataFormat = result.getDataFormat()
int dataType = result.getType()
double result;
switch(dataType){
case Tango_DEV_Double:
switch(dataFormat){
case _SCALAR:
result = attribute.extractDouble()
...
}
...
}
...
Using the API the same result can be achieved with the following code:
TangoProxyWrapper proxy = new TangoProxyWrapper("some-device");
double result = proxy.<Double>readAttribute("some-attribute");
...
This library will be a part of the Tango distribution since version 9.
