[Gpdtc] Fwd: [EXTERNAL] Topical collaboration....

[Cloet, Ian C.]

Hi David,

Thanks for forwarding this. I am happy to meet this week or next. Perhaps a when2meet would be helpful to find a good time.

Cheers, Ian

My reading is that it would be good to start planning in earnest pretty soon so that we have a strong proposal whether there be two  or a combined one.   I realize some of you are still on travel, but perhaps we should aim to have a call later this week, or early next?  In the meantime, it would be good to start refining the material in the overleaf page, and in particular whether we can “firm up the overall goals” any further.

We’ve been having discussions about this focused both on the physics, and on the potential to create university bridge positions.  At the moment, we’ve had discussions amongst participants at ANL, JLab/Hampton/WM, Temple, UConn.
