Electronic Review (I)
A review has been made on December 9 and 10 in Berkeley.
DOE asked for 3 experts in Berkeley.
(Bryant, Freedman and Kadel were also present)
Reports were from:
Gianluigi (with Claudio) on the Electronic Project;
Frank about the production and founding;
Huan about testing.
The project is mature;
Investigation of the observed anomalies on some channels with the pulser;
provide details about the founding needs;
provide details on the testing procedures.
Conclusive remarks:

The PEN tapes link system from the Mixing chamber down to the detectors and the heaters has been fully designed for both CUORE and CUORE0.
PEN tapes for CUORE0 will be available starting from the next week;
Test tapes or CUORE in various geometry will be also available by that time.

Detector Link (II)We have arranged the production in order to have the tapes cleaned and packaged under vacuum at the production stage.
The cleaning has been made using our selected tissue and propilic-alcohol.

Considerations:
1. With respect to the original layout, room has been added to some tapes at their bottom for the implementation of thermometers able to measure the far location of the detector frame. These thermometer have to be low-radiation compliant.
2. On some Kapton boards, one per column, room has been made available to add 5 differential connections for the readout of thermometers and the like.

Power supply system
The DC-DC design of the power supply system is finishing (thanks to the support from Alessandro Bau and Andrea Passerini). It can be controlled and configured remotely like the other devices.A prototype is under development.
The linear ultra-low drift and low-noise supply voltage is going to be upgraded.

Digital data link
A CAN bus based optical data link has been developed and tested for the control of the electronic system.
The link is either Linux and Window OS compatible.

Production Precautions
It is mandatory to ask:
PCB producer: electrical test.
PCB population:
Automatic Visual inspection test;
In Circuit Test, ICT.

Testing and Calibration (I)
Testing procedure must be defined accurately.
It can be made in 2 steps:
1. Functionality test (at UCLA);
2. Temperature characterization/calibration (in MILANO with UCLA people)
A number of adaptor boards has been made that has been/will be the support for UCLA functionality test.
