SudarshanK, RichardS,
Summary:
We moved the Pcal beams on ENDX ETM about 14 mm away from the their optimal position of +/- 111.6 mm in y direction. They were moved away from the center of the optic. We had moved the beam about 7 mm from their optimal position towards the center of the optic last Tuesday.
Details:
We moved the top (inner) beam by moving the mirror mount in pitch in anticlockwise direction. We had to move the adjustment screw little more than quarter turn to achieve the beam movement of about 22 mm. (from -8 mm to +13 mm). For the bottom(outer beam) we moved the mirror mount in yaw in anticlockwise direction about quarter turn to achieve similar movement as the top beam.
The position of the Pcal beam spot from their optimal locations before and after are as follows:
| Before 07/25/2017 | 07/25/2017 | 08/01/2017 | |
| Upper Beam | [1.9, 0.3] | [2.5, -8.4] | [1.1, 14.5] |
| Lower Beam | [-1.0, 0.3] | [-1.3, 8.6] | [-0.5, -14.1] |
