There is the remaining field from the dipoles in the TL. In order to go straight to the dump, the idea was to cycle the dipole to have 0 field. We have tried the cyclage given by the ALBA peopel/Cynthia. Total time ~ 17 min. After two cycling, the remaining filed alwayd stays at ~20 G.
After discussion of Jean-Noel with Fabrice Marteau, this turned out normal situation given the unipolar PS of the dipoles. The remaining filed is kind in agreement with B(I) found in excel files provided long time ago by Cynthia.
The information concerning the dipole cycling from Cynthia is attached. |
