Thank you Marc for the summary.</div>

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.</div>

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.</div>

DSG conducted a meeting to discuss the development and design of a mapping fixture for the Moller TM0 magnet. Minutes from that meeting can be reviewed at the following link and are attached to this email.</div>
