• Circuit boards: About 190 fully soldered circuit boards have been transfered from ODU to JLab. Samuel and Edward have started testing the jumper wire soldering on some of those. They also started a complete database of the circuit bases including the measured value of all resistors (measured with an ohmmeter).

 
• Ti flange gluing:  336 flanges have been glued so far. Half of the blocks will be glued by December 1st. The rate is about 12/day. Within 1 week, all the blocks at JLab will be glued.

 
• Sockets/pins gluing:  635 sockets are ready so far. Hakob will arrive on Dec. 10th and will bring some more pins so we can complete this job very fast (rate is about 20/day).

 
• Al flange gluing:  Armen, Edward and Samuel are currently looking into a system to glue the Al flanges correctly. I have brought 7 Al tubes at JLab but more will be ready soon (they are all cut, but not all deburred).

 
• DAQ-proton arm:  Ting is still setting up the mini-DAQ in the EEL building. He reported on what we need in terms of modules/crates/racks for the proton platform. Ask Ting for more details about his presentation.

 
• DAQ-photon arm:  I have presented a drawings of the racks arrangment for the calorimeter. It was basically Albert's latest design. The cables from the linear summing modules and the patch panels are already in and very short and I need to change that design so we can connect those. I will have a note ready by next week and will present it at the meeting.

 
• HV control:  Eugene reports that Roman will work on programming a JAVA interface for the control of our HV. The only issue is that one of the mainframe is not ethernet compatible. We will have to switch with one which is compatible.

 
• Wires/heat shrink tubing/springs:  The heat shring tubing is in. 1000 feet of jumper wires is in and currently under tests. We need about 4000 feet, which I will order as soon as I have the confirmation we have the right kind of wire (7 strands, teflon coated, 600V rated and resistant to 200 degrees C, about 44 mils diameter). 1000 springs will be there on December 8th.
