Iris | Drawing of present setup |
This is the setup which was used for the Ni runs (from Nov. 8th evening on).
Note (Nov. 10th): Alejandro built a U-shaped Pb wall, the degrader inside AIDA was removed and possibly a Al plate was installed. This has to be checked when access is possible again.
> Attached is the present setup including all walls, auxiliary detectors, degraders etc. and the Takechi setup.
> The lead wall will be removed for measurements (of course...).
> Not to scale! Some sizes and distances included. Pictures see Jose's entry ID 110.
>
> Note the shape of the active area of the DeltaE Silicon detector, see previous entry. |
