I think the angle of incidence on TT inside BSC will be too large because of eddy current damping brackets. I've measured max possible angle of incidence

Max angle of incidence, degrees |
| No bracket |
72 |
| Original bracket |
45 |
| New bracket (with no screws for tiny yaw magnets) |
52 |
This means that we do not have too much range and there is a probability that 45 degree incident beam will start clipping. I think we should just cut off the central part of the bracket. We do not need it anyway, our eddy current damping due to corner magnets is good enough.
I've left the brackets near the laptop in the clean room. |
