[dsg-halla_moller] September 5, 2025 Moller mapping fixture meeting

[Sandesh Gopinath]

Thank you Marc for the summary.

To be explicit, the alignment (angle in phi/360) of the probes to the coils after installation is critical. We should aim to match the central axis of the probes in the probe holder, to match that of the 2-bounce shield, but it's acceptable if off by a small amount. Based on the initial design concepts, we can decide what this small amount needs to be- if at all necessary.

The aim in the coming days should be to evaluate the viability of a design that meets the requirements, along with an estimate for the materials/machining cost necessary.

Thanks,
Sandesh
