keyword=Single 1-C Septum scanWith a 1-C carbon foil (no BeO), collimators in, sieve slit out, we scanned the septum current between 78.6A and 138.6A.
At all settings we had a broad stripe at the maximum x_rot. However, at higher current a new, "narrow" in y_rot (translates to the scattering angle) and very broad in x_rot (momentum) stripe developed, probably due to pulling particles through material in the septum.
Run _____ Current
1329 _____ 78.6A
1328 _____ 88.6A
1327 _____ 98.6A (nominal)
1330 _____ 108.6A
1331 _____ 118.6A
1332 _____ 128.6A
1333 _____ 138.6A
