Bettina:
50-160Meve ---> less space charge
reduction in lhc filling time
new injection scheme profiting of chopper in L4 and stripping
new distributor
once it's done, forget about linac2 (of course injection will not be possible anymore)
increased brightness of PSB beams.
higher energy-->reduced space charge tuneshift
PSB beam production:
PSB covers up to 10**13 per ring
Linace 4 will need to produce all present beams (also in terms of emittance
Tables with beams produced with linac2
