 - We discussed what else is needed to finish the package installation. We will install plastic manifolds for the gas (instead of the aluminum ones that we have now), and will make also the connections between the cooling manifolds. Important question about the grounding connections. One of the results of the test with the full electronics is that we don't need additional grounding of the wire and cathode frames. According some experts, the connection of the detector to the Hall ground is needed only for safety. In 126 there's no such connection and the noise is low. Therefore, we can have one ground cable for all the packages and it doesn't have to be thick.
-- We discussed if we can use 1/4" tubes for the gas inside the solenoid. These tube will fit in the gas manifold. Outside tubes are 1/4".

+- Beni and Vlad did a lot of work recently on the electronics and the detector to make almost all of the channels working now.
