Detailed report: link

We moved back the XPcal beam positions to the designed positions because they moved during the Xend pumping.

The last positions after our adjustment are ([0,0] means the designed position)

• path1[mm]:  [-0.64, 0.92]

• path2[mm]: [-0.63, -0.30]

The optical efficiency from Tx to Rx was 94.5% after the adjustment, which is similar to before. (klog 19086)

After the work, we turned OFF laser, Tcam, script for pico, picomotor power, and LED.

Attached pictures are before and after the adjustment.
