A few keywords about East Area Operation
*Keywords*		*Description*
SE 61		Slow extraction of the beam from straight section 61 in the P.S. machine
*Beam Lines*
F61		Transfer channel, from PS extraction septum magnet SMH61 (excluded) to the 2nd beam stopper F61.STP02 after the splitter SMH01 (included)
F61N		Transfer channel, from end of F61 to the north branch target station (included)
F61S		Transfer channel, from end of F61 to F61S.BHZ02 (included), last horizontal bending before south branch target station
ZT7		Transfer channel, from end of FE61S to LHC B (T7) reference focus
ZT8		Transfer channel, from end of FE61S to DIRAC (T8) reference focus
ZT9		Transfer channel, from end of FE61N to ATLAS/CMS (T9) reference focus
ZT10		Transfer channel, from end of FE61N to ALICE (T10) reference focus
ZT11		Transfer channel, from end of FE61N to (T11) reference focus
Areas
T7		Area housing beam line ZT7 and the LHCB test place
T8		Area housing beam line ZT8 and the DIRAC experiment
T9		Area housing beam line ZT9 and the ATLAS/CMS test place
T10		Area housing beam line ZT10 and the ALICE test place
T11		Area housing beam line ZT11 and a general purpose test place.
Access
Access to any of the areas T7c, T8c, T9c, T10c and T11c does not prevent beam from going to other areas.
Access to any of the area T7a, T8a, T9a, T10a and T11a prevents beam from leaving the PS ring area.

A few keywords about Pulse to Pulse Modulation (PPM) for the East Area Operation
*Keywords*		*Description*
*Users*
EASTA		PS cycle, mainly used for T7, T9, T10, T11
EASTB		PS cycle, mainly used for T8 (DIRAC)
EASTC		PS cycle, combined operation TOF / T7, T9, T10, T11
*Beam Lines*
DN0		All beam to the north branch, within splitter gap, splitter off
DN1		All beam to the north branch, outside splitter gap, splitter on (or off)
DS7		All beam to the south branch (to T7)
DS8		All beam to the south branch (to T8)
DNS7		Beam shared between north and south branch T7
DNS8		Beam shared between north and south branch T8
PPM features of Magnetic elements
Non PPM		The power supply pulses with the same value for all cycles and / or destination
Partial PPM		The power supply can pulse with a different value from one cycle and / or destination to the other but they should not be consequetive.
Full PPM		The power supply can pulse with a different value from one cycle and or destination to the other.
