Contact People: SPSU team, H. Bartosik, B.
Salvant
Additional remarks:
Thursday 07h00 - Thursday 14h00
PS MD title:
Tests for a slow extraction of protons at 2.12 GeV/c from the PS to the East
Area
Beam conditions:
EAST-type beam

PS user = EASTA
SPS user =
RF MMI target =
Contact Person: O. Hans, S. Gilardoni, R.
Steerenberg
Additional remarks: Beam to the East area will have to be stopped during this MD, because special settings of the extraction elements are required, which are not PPM
