PS MD title:
Test for the use of new gama jump quadrupole
Beam conditions:
all beam types
PSB user = TOF
PS user =
TOF
Contact Person: S. Gilardoni, H. Bartosik, M.
Giovannozzi, C. Hernalsteens, A. Lachaize
Additional remarks: This MD could perturb other users. The purpose of this test is to check whether the space presently occupied by the gamma jump quadrupole can be freed and used for the installation of a dummy septum for MTE. At the end of this MD dand depending on its outcome, a PS might be required to return to the original configuration (~1h without beam for the SPS)
