ANISE: Active Network for Information
from Synchrotron Experiments


“Active” means near
-
instantaneous stream processing of complex data during
transfer to the user or to storage.


Cell processing using Infosphere Streams software from IBM and lightpath
provided by CANARIE network.


Distributed processing on facilities provided by SHARCNET and WESTGRID.


Objective:
Develop such a network to provide processed results from
experiments such as Laue diffraction at APS (34
-
ID) and VESPERS at CLS




The network would assist the integration of diffraction data from multiple
and large area detectors.




The network would facilitate faster resolution of research problems and free
up time for more users.




The network would encouage common data formats and protocols leding to
closer collaboration.

Some project outcomes:


1 Accessibility of Laue diffraction methods to a greater number and variety of
users could be achieved by reducing the time required to accumulate
meaningful data.


2 The results of complex diffraction measurements involving a e a wider segment
of angles could be assessed rapidly..


3. Data and experiment management processes of Science Studio could enable
very brief follow
-
up experiments to answer crucial questions sometime later.


4.. Distant collaborators could participate in, and learn from experiments on
samples of critical importance to a project.

.

5. User support software could man a more rapid publications.


6. Expansion to include other beamlines (potentially at APS).

Goals


Science Studio

serves three purposes:


Management of all aspects of a scientific experiment
including data storage, collaboration with others,
processing of data;



Control of, or interaction with, remote experiments on the
CLSI VESPERS Beamline and UWO Nanofabrication
Laboratory and



User Services (sample management, scheduling, peer
review, user training)

Other requirements


Low cost, both in initial licensing fees and operating costs


Distributed environment: used at multiple facilities


Easy to change


Large amounts of data, fast response times


Data is secure


Increases the effectiveness of laboratories and devices


Reduces need to travel to facilities.

8

More Design Objectives


Built to be useful to scientists:



Easy to find information



Information is entered once and reused



Information kept organized, safe, and easily shareable



Utilities available to promote collaboration and teamwork.



System allows for task and sample management

9

User Access to Synchrotrons


Synchrotrons are electron storage rings that emit high intensity
radiation spectrum ranging from IR to x rays. Access is normally
granted for single periods of 2
-
3 days in a half
-
year cycle.


Episodic access requires careful pooling of samples



Little or no time for analysis of data during the experimental
access.



Reprise experiments difficult to schedule



Travel is expensive and inconvenient



User control and records of experiments at the site is
sometimes limited.
