Cable Channel tests
____________________________________________________________17/Apr/07 Pisa Group
•Four configurations of insulation has been tested in the following condition:•T fluid -23 0C power off•T fluid -13 0C power off•T fluid -23 0C power on (1 watt/m)•T fluid -13 0C power on (1 watt/m)•Next tests:
•Mechanical e thermal Considerations in the real channel.

•We were trying to improve the uniformity of temperature.•For this reason we are adding on the cable bundle an aluminum foils of 0.2 mm •The test will be done on conf5.

•Several sections have been found.•The channel are taper. The section of cable and tube must be adapted at the different sections

Summary
____________________________________________________________17/Apr/07 Pisa Group
1. For the connector there is no problems of condensation.2. Internal flow must be assured to keep the channel dry for safety3. In the condition of -13 0C and max power the plate was at 22.1
+/- 0.2 0C and no variation with no power and min temperature -22 0C. This was placed underneath the channel. These are the extreme condition.
4. An effort to improve the uniformity of temperature must be done.
