  3. STS-CBM thermodynamical requirements • The requirements for the STS cooling are twofold: • The innermost sensors with high radiation load have to be kept at or below -5 ⁰C • Cooling based in gaseous, convective cooling of the (innermost) silicon sensors and other heat generating components, like power cables. • Complete removal of the heat dissipated by the front-end electronics boards. This a prerequisite of the first requirement. • System based in an evaporative CO2 cooling of the front-end electronics, which is located in the FEE blocks. • This kind of evaporative cooling based on CO2, is also under consideration and thus under intense technical development for upgrades of the silicon trackers of LHC experiments. The total heat power dissipated by the STS components is estimated as: 212 FEE blocks at 200 W (10 FEBs with 20 W each), resulting in a power dissipation of 42.4 kW. The innermost sensors around the beam pipe with the highest radiation load will dissipate in operation around 6 mW on (2 x 3) cm2 after the accumulation of a certain radiation dose.

  10. 5b. CO2 Line: Pulsation Dampener Necessity of a pulsation dampener to prevent pulsations which produce negative effects in the stability of the temperatures and therefore in the heat extraction by the biphasic system. Dampener effect • Discharge pressures LEWA pump: • Pd,min=22 bar Pd,max=79 bar • Pmin=P1=20.9 bar Pmax=P2=82.95 bar • Dampener should be able to work in this range. • Pt ≈ theoretical or work pressure. Residual pressure admitted ±5% (by now) • P1 = Pt1 - ( 5/100 ) ∙ Pt2 = 20.9 bar (1) • P2 = Pt2 + ( 5/100 ) ∙ Pt1 = 82.95 bar • Plunger: ø=25mm L=15 mm dv=7363.11 mm3 • If V1 = V0 – v,     and     v = 0.1 ∙ V0 • We have V1 = 0.9 ∙ V0        (2)  • And also V2 =V1- dv        (3) • From (1) and (2) we obtain P0=0.9xP1 = 18.81 bar     (4) • Finally from (1) (2) (3) and (4) we will obtain: • P0 ∙ V0=P2 ∙ V2 ; 0.9P1 ∙ V0=P2 (V1-dv) =P2 (0.9V0-dv) • From the underlined equalities we have the final formula • This will change the charging gas value at 20 ⁰C (take note that for a 10 ⁰C of temperature variation the gas pressure will change approx. a 3%) • This volume has to be equal to ”V2” from the formula P2/P0 = V0/V2 then: • ( V0 / 13.67 ) = ( 82.95/ 18.81 ) and   V0 = 60.28 cm3 • Values for a possible version applied in TRACI-XL: • Bladder: NBR Low Temperature -40/85 ⁰C • With 150 ml of oil for low temperatures inside the bladder • Pre-charged at 18 bar Work Package 13 - CO2 Cooling - Jorge Sánchez
