Measurements performed by SSD - 104/09, 16:30 - Dessica started with this setpoints:

- RH: 15% (--> 2.03 g/kg)- T: 19 deg (measured near the machine ~18.3 deg, decreased to ~16.6 in the following days)- Flow measured ~314 m^3/h that increased to ~330 m^3/h in the following hours- P measured ~1.5 kPa

- SSD C2-sensor RH (at the detector entrance): ~26%- SSD A -sensor RH (at the detector exit) : ~26%- A624: 195 uA- C601: 400 uA

07/09, 09.30 - Flow reduced to ~ 300 m^3/h, other parameters fixed

- P measured: 1.26 kPa- SSD C2-sensor RH: ~20.3%- SSD A -sensor RH: ~21.5%- A624: 180 uA- C601: 375 uA

Page 15: SSD Status  Before  and  After Dessica Installation

10/09, 09.30 - RH setpoint reduced to 10% (-->1.35 g/kg), other parameters fixed

- SSD C2-sensor RH: ~16%- SSD A -sensor RH: ~18%- A624: 160 uA- C601: 332 uA

11/09, 09.30 - Flow reduced to ~ 250 m^3/h (the nominal one), other parameters fixed

- P measured: 0.864 kPa- SSD C2-sensor RH: ~16.8%- SSD A -sensor RH: ~17.9%- A624: 157 uA- C601: 327 uA

Conclusions• SSD condition significantly improved:

– RH stable at the requested values– Critical half-ladders current decrasing (a complete stabilization needs

more working weeks at the proper RH conditions)

• Further interventions– Leak check then redo the flow measurements– Pipe insulation (to gain in terms of air temperature at the detector),

• Dessica settings to be kept: 250 m3/h, RH 10% (1.35 g/kg)
