On last Friday, we found that there is a potential problem with QUAD 9, 10 an 12 as by switching them OFF, we obtained better transport and finally had the evidance of the seconf full turn.

RI-C2/PS/QP.09

RI-C2/PS/QP.10

RI-C2/PS/QP.12

Today, we checked the polarity and found that the polarity of the RI-C2/PS/QP.10 was inversed at the level of power supply (even though was checked last time in July). We have restore the good polarity of the RI-C2/PS/QP.10 by swapping the cables at the PS. 

We plan to check the beam transport in the afternoon.
