Sheila, Raed, Camilla. WP 12559. Repeating work at EY: 81358
The EX ALS shutter wasn’t all way closed when we arrived, even after opening and closing it’s the stayed the same, partially closed, see photo in "closed" position and video. Opened FRS issue #34149 .
Attached the beamscan data we took. Beam looked nice and gaussian even though it was astigmatic. Example photo attached, I have all other photos.
We again checked the HWS beam that we don't like much and confirmed that the shape wasn't Gaussian, it looked like a top hap and the HWS beam profile is attached soon after the collimator.
