• Various prototypes tested• Stable operation:

– up to a power duty cycle of 95%

– with simple On/Off control• Temperatures of heating

element OK (max around 60 °C), far from max limit

• Design mature and ready for final prototype

• pressure drops and occupancy of extrapolated final size OK

Detector loopDetector loopHeat exchangerHeat exchanger

• Design is different for the three sub detectors due to different layout and geometrical constraints

• All countercurrent type• Pixel: parallel type external.

Al inlet and return tubes glued together over 1.5 m. Simple design, possible with small power load

• Barrel SCT: parallel type internal. Two inlet tubes are routed inside the return tube over a length of 1.5 m and parallel to the return tube axis

• EC SCT: inlet tube is coiled in spiral inside the return tube over less than 0.5 m.

15



Detector loop Detector loop CapillariesCapillaries

• Flow is function of: Dp, length, ID, inlet liquid T (HEX efficiency)

• Flow very sensitive to ID change: need test every capillary during production trimming the length to get the right flow

• Hundreds of data taken, but extrapolation is not easy, so need to check almost every geometry/condition

• Final capillaries for EC SCT are available. 2 IDs: 0.68 – 0.76 mm (we ordered enough quantities of the bigger ID sufficient also for barrel SCT if it will turn out to be correct)

• A test setup is being built to trim the capillaries to length

Pressure drop across against mass flow through capillary (ID=0.65)

P(6m)= 13.423x + 1.0074R2 = 0.9929

P(5m) = 11.48x + 1.7971R2 = 0.9905
