- Bill: two spacers are ready, the last one will be glued right after the meeting. Pictures of the spacers, the fixture and the gluing are attached above. The carbon fiber rods are glued to the g10 cylinder. The two gusset rings needed for this procedure were taken from the spare package which is sitting now on a granite table with two Lexan sheets on both sides. Tomorrow after the last spacer is ready, we will put the gussets back. This operation requires at least 4 people, since we use metal pins inserted in the six places when lifting the Lexan sheets. As in happened already when taking the gusset ring in the same way, the pin can lift some of the planes/cells up.

- Lubomir and Vlad showed some results from the thick cell study with a scope. We used two differential probes connected to wires from the two top cells. We used the scope as a trigger and fADC: we triggered on coincidences from the two wires, thus selecting almost vertical MIP that crossed the whole volume above the the wires. We recorded manually about a thousand events and plots linked above represent the results from their analysis.
