I brought up that what we really need is a higher temperature in the meeting and I think what Nikki's (and it's probably from the ITS3 folks as well) concern isn't really just the adhesive itself, but the CTE of the assembly. Still, I would think they need
to investigate other adhesives in any case to find one that has better properties, more flexible maybe?</div>

So they'll need to do more studies in any event so I think (hope?) a lot of this is just laying the foundation for that.</div>

I still think even getting the center of the beampipe to 100C is going to be a big challenge and that the temperature of some of the other sections is going to be significantly hotter, which might impact other detectors than just tracking.</div>

<div class="">indeed this looks to me reinventing the wheel. Should one not put more effort on the adhesive and find one which can stand a higher temperature.</div>
