                the geometry. The changes needed for the upgrade should
                not be too bad.

              </p>
              <ul>
                <li> The PR for 17 additional phototubes has gone into
                  Procurement. We should inventory the spares already in
                  hand at JLab.</li>
                <li> Polishing supplies that Paul requested were ordered
                  from MSC. They should arrive at FSU tomorrow.</li>

              <p>Tim reported:
              </p>
              <ul>
                <li> Everything in the Hall is ready to go.</li>
                <li> Nothing will be done until the DIRC installation is
                  complete, probably several more weeks.</li>
                <li> JLab has the drawings in hand for the brackets and
                  will send them out to be made.</li>
                <li> Collars will made at FSU.</li>
                <li> Paul reports that they have reviewed the drawings
                  Stephanie Worthington sent and they look good.</li>
                <li> Paul expressed some misgivings at the design of the
                  racks to store the modules when they arrive at JLab.
                  He and Tim will discuss this further.</li>
                <li> The gluing fixture will be mounted in the Hall as
                  it was during the initial installation.</li>

              <p>Paul reported:
              </p>
              <ul>
                <li> The scintillator bars have arrived at FSU. The
                  boxes will get opened tomorrow. Inspection routine
                  will be performed.</li>
                <li> Paul will be sending in an order for more RTV and
                  primer.</li>
                <li> The current batch of light guides are ready to have
                  their ends trimmed off.</li>
                <li> The ESR forming device is getting made.</li>
                <li> Paul has been thinking about the beam support box
                  needed for air light guides across the beam hole.</li>
                <li> Ashley asked if we would need lucite shielding in
                  the new configuration. The DIRC will provide some
                  level of shielding but not over all of the TOF near
                  the beamline. This will require further thought.</li>
              </ul>
              <h4><span class="mw-headline" id="Software">Software</span></h4>
              <p>Paul pointed out that there are many software tasks
                that need to get done to support the new configuration
                beyond the geometry specification.
