In the TCS chiller room I increased the flow of the fan coil (up to level II of three) and I turned ON the chiller guardian in order to reach the thermal steady state during the weekend. 

NI CO2 BENCH
The DAS quality has been checked after the realignement of the pin hole performed Monday 10th (51721).
As expected, the distribution of the power appeared quite bad (see fig 1 and 2). Thus, we acted on two different mirrors along the inner and outer rings layout to recover a good power distribution on both rings (see fig 3).

WI CO2 BENCH
The same check has been performed on the WI bench. The DAS is shown in fig.4.
