Nick Hauser NOBUGS 2014 Sept 24-26 Tsukuba

Adding spokes…

• Tried not to reinvent the

wheel…

• …just to add spokes to

an existing wheel

• ‘Unfortunately’ several

systems were developed in parallel in early 2000’s. Sardana, GDA, IROHA2, CSS - BOY Gumtree…

• Use Mantid instead?

OPAL Reactor

• Multi-purpose facility

– Isotope production – Si NTD – Materials Irradiation

• NAA & DNAA

– Neutron beams

• 20 MW
• Open pool
• Compact core
• D2O reflector
• Plate type Low Enriched Uranium fuel
• Commenced operation 2007

Good news since last meeting

Good news since last meeting

SANS Powder (high int.) Reflectometer Powder (high res.) Laue Diffract. Strain Scanner TOF Inelastic USANS Back- Scattering Crystal Alignment SANS2 Operating instruments (7) Construction/commissioning (7)

gumtree ecosystem

made possible by Eclipse plugins – adding spokes to a wheel

Lesson 1: Activity without productivity

Solution

• Simplified APIs
• Smaller team

Lessons 2: Slow development

Solution

Standardisation

14 instruments

Gumtree 77% SPICE 7% IGOR 8% Visual Basic 8%

Control GUI

SICS and HM server 84% SPICE 8% VB 8%

Control server Histogram server

Gumtree 31% Mantid 23% Igor 15% Others (4) 31%

Data reduction

Major plug-ins / features

• Data plug-in for read/write/processing
• Visualisation
• Workflow
• Scripting for all the above
• Instrument usage statistics

Common Data Model Access CDMA

• Please consider this as a way to share data within plugins in an
• application. Java or C++
• Never write another file reader / exporter again
• Reads/writes hdf5, netcdf, xml file
• Output / exports to hdf5, xml, cif, xyd
• C++ and Java versions – Mantid integration?
• jython/jnumpy API for data & array operations
• error propagation for neutron scattering (Poisson stats)
• Successful collaboration with Soleil. Both facilities benefited.

Open to further collaborations

• https://code.google.com/p/cdma/

Multi sample workflow

• Automation interface & engine for instruments with

sample changers, sample environment controllers and instrument configuration changes e.g. SANS

• generated xml file has file associations e.g.

transmission, scattering, empty cell – automated data reduction

Using a statistical approach

Data Reduction and Scripting in a Browser

Gumtree Server

SETUP

• 1. Run a predefined

script, or upload one

• 2. Create GUI will

execute script on the server and present an HTML UI bound to serverside objects

Data Reduction and Scripting in a Browser

Gumtree Server

RUN

• 1. Configure your reduction

through the UI, select

• ne or more files and

Run Script

• 2. Returns result as zip
• 3. Console widget echoes

script progress

• 4. Further data processing

and visualisation is available on the jython command line DEMO

Gathering usage statistics

Gumtree helps in the management process to maximise instrument productivity

rich client, poor client

executing experiments on Gumtree server

virtualisation

reducing admin workload, making systems robust
