Today we tried to recover the center of the HWS-INJ SLED beam on the WI mirror. The starting point is shown in fig.1.
We performed 3 different steps acting on the steering mirror EIB_Har_M0 (see fig.2).
The procedure was:
-put EIB on the ground
-act on the steering mirror
-re-suspend EIB
-relock cavities on the IR
-put WI single bounce
-start HWS-INJ measurement
-switch ON the CH
-evaluate the position in the HWS map
The three different movements are summarized below:
-
VERTICAL (wrong direction)
-
VERTICAL (right direction but slightly misalignment in the horizontal direction)
-
VERTICAL and HORIZONTAL
The effects of the movements are shown in fig.3.
The activity has to be completed.
