<li> We are just about to order scintillator material
from Eljen. Paul obtained a quote. This time Eljen is
saying that they cannot hold a 5 mil tolerances on the
cast surfaces; we don't need that level of precision
on that dimension in any case. Paul has revised the
specifications we used for TOF I and sent them to
Mark. Eljen says they are not too busy right now.</li>
<li> We are also ready to order acrylic rods for the
light guides. Paul has located a vendor.</li>
<li> We need to get going on these procurements as soon
as possible.</li>
<li> Paul showed a sample light guide (see the beginning
of chapter 2 of the recording, linked above). Making
it exposed tooling needs for production. Paul is
collecting the existing tooling and clearing space for
construction and storage at </li>
</ul>
<p>FSU.
