Madi, Camilla, TJ. Repeating work at EX: 90370

Ingoing ALS beam measured between L6 and L7. Beam shape is better than at EX but still has strange astigmatic artefact.

Return beam arguably worse than at EX. Demonstrating the same lobed behaviour, with an overall 'peanut' shape.

Nanoscan head was tilted 45deg at each measurement point, to get comprehensive view of the beam. Both sets of measurements attached.

Pellicle beamsplitter has been left on table at EY.
