Roadmap

Milestone 1 - CRYRING-focused (Early 2020)

Milestone 2 - alpha version (not planned date yet)

Milestone 3 - extended list of features (not planned date yet)

Layout

Highly configurable dashboard layout vs fixed (per ion source type) dashboard layout

Aleksey and Gleb like the idea of a highly configurable dashboard layouts and following ideas in particular where discussed:

• Freely positionable instruments, data/time plots and other views like on a blackboard.

• Freely scaleable, instruments, data/time plots and other views to optimize the available space on the screen.

• (Expert-)User can save the layout for later reuse.

For (non-expert) users controlling and monitoring the ion sources their was a common agreement that flexibility of layouts can be confusing and complicate operation. For Aleksey and Gleb this stands above the needs for an highly configurable dashboard. An agreement was reached defining that one layout for each ion source type will probably be sufficient. The layout is designed with the help of the ion source experts. The layout possibilities might have limits in terms of size, scalability and technical boundaries. The layout must be configurable in a way that expert input can be realized and the layouts can be progressively improved from time to time.

Longterm idea

Aleksey presented an interesting form of laying out instruments in groups (or grouping boxes). Those groups are a form of abstraction/presentation of physical parameters of ion sources instead of only putting into focus the instruments of the involved devices. Additionally the grouped instruments are reduced to only show view elements which are really needed for the particular instrument. This approach makes the ion source easier to understand and control and also reduces the amount of space in total needed on the dashboard.

The changes to instruments and layout would be mainly:

• Use 'physical parameter' as title
• Used device namen and nomen in status (single status only used here)
• An single instrument would be higher in most cases
