| MOCPL01 | IBEX: Beamline Control at ISIS Pulsed Neutron and Muon Source | 59 |
|
||
|
For most of its over 30 years of operation the ISIS Neutron and Muon Source has been using bespoke control software on its beamlines. In the last few years, we have been converting the beamline control software to IBEX*, which is based on the Open Source EPICS toolkit**. More than half the instruments at ISIS are now converted. IBEX must be robust and flexible enough to allow instrument scientists to perform the many experiments they can conceive of. Using EPICS as a base, we have built Python services and scripting support as well as developing an Eclipse/RCP GUI based on Control System Studio***. We use an Agile based development methodology with heavy use of automated testing and device emulators. As we move to the final implementation stage, we are handling new instrument challenges (such as reflectometry) and providing new functionality (live neutron data view, script generator and server). This presentation will cover an overview of the IBEX architecture, our development practices, what is currently in progress, and our future plans.

At the ISIS Neutron and Muon Source, we are in the process of upgrading from the LabVIEW-based SECI instrument control system to the new IBEX control system* based on EPICS**. It is crucial to the running of experiments that IBEX has a high uptime and few bugs. However, it is often not possible to test the system live on an instrument prior to an experiment and thus we must be sure that it is ready to go as soon as we have users. To test that we are correctly communicating with hardware we have built a framework to automate testing of EPICS IOCs using device emulators created using the LeWIS*** Python package. This lets us test that new drivers are functionally the same as those under SECI. To ensure that the full instrument control system stack is working as intended we are also using the Squish testing tool****. Whilst this is used by industry as a GUI focused tool we have used it in conjugation with a fully simulated IBEX installation to create system tests, letting us directly simulate the interactions a user has with IBEX and validate its behavior. This poster will present how using these tools has made IBEX a more robust system.
