Fourth ESS Experiment Control Workshop

7 Dec 2016, 09:00 → 9 Dec 2016, 15:00 Europe/Stockholm

DMSC at COBIS

This is the 4th workshop in the series to exchange information on progress, thoughts and ideas between all partners involved in the development of the ESS experiment control system.

Wednesday, 7 December

09:00 → 17:40 Hands-on Sessions

09:00 Welcome

Speakers: Jonathan Taylor (European Spallation Source ERIC), Michael Wedel (European Spallation Source ERIC)

09:15 Plankton Device Implementation Howto

Speaker: Michael Wedel (European Spallation Source ERIC)

10:25 Coffee

10:45 Approaches to Visualising and Inspecting Voxel Data

Speaker: Mr Lamar Moore (STFC/ISIS)

Slides MultiGridWorkshopPresentation.pdf

Minutes from the Voxel Data session:

• Morten Christensen to provide more cncs data for evaluating voxel geometry
• Morten highlighted the need for more collaboration among groups In-Kind, Detector group, DMSC etc and he will drive this effort.
• Lamar to come up with scheme for loading entire CNCS geometry with data into Paraview for evaluation.
• Geometries must contain full single-pixel resolution for multigrid detector based instruments initially. Binning, sub-sampling and/or flattening of the instrument geometry will be discussed later on.

11:55 Lunch

12:45 EPICS and Motion Control

Thursday, 8 December

09:00 → 10:35 Progress updates

Short updates on progress relevant to the control system

09:00 Scanning instruments in Mantid

Speaker: Mr Owen Arnold (ISIS)

Slides scanning_updates.pptx

09:40 NICOS at V20

Speaker: Michael Wedel (European Spallation Source ERIC)

Decisions:

• Further explore use of simulation framework to create simple CA interfaces for devices (together with Mark K.)
• Requires proper implementation of socket device starting from prototype (asynchat, Michael H.)

10:15 Coffee

10:35 → 13:00 Logging

Discussions about logging infrastructure and technology choices. Special guests: Kareem Galal and Brian Lindgren Jensen from DST group.

10:35 Findings about Graylog/ELK

Speaker: Mr Nilsson Jonas (DMSC)

Decisions:

• Use graylog for now
• Jonas to prepare vagrant file, put into repository, use in VM for local testing
• One instance deployed at ESSIIP for "real world test"
• Use syslog severity levels
