Next tests: ____________________________________________________________ 17/Apr/07 Pisa Group 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.

Mechanical e thermal Considerations in the real channel. ____________________________________________________________ 17/Apr/07 Pisa Group Several sections have been found. The channel are taper. The section of cable and tube must be adapted at the different sections

Mechanical e thermal Considerations in the real channel. ____________________________________________________________ 17/Apr/07 Pisa Group

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 safety 3.In the condition of C and max power the plate was at / C and no variation with no power and min temperature C. This was placed underneath the channel. These are the extreme condition. 4.An effort to improve the uniformity of temperature must be done.
