the plan...
Commissioning almost complete
Beginning July start with 3x3 bunches and gradually increase weekly to 6x6,12x12, 24x24 by the end of july.
Stable run under constant conditions all of August.
Bunch Train operation in September.
Bunch Train Operation?

V. I. Balbekov has computed the tune shift along a
uniform train or batch of proton bunches for the high
intensity UNK machine [1]. The origin of this effect is
the complex transverse resistive wall impedance. It is
computed here both for the SPS (fixed target and LHC
beam operation) and for the LHC. It modifies the stability
situation of the bunch train when compared to a machine
which is uniformly filled. In the latter part of the paper it
is shown that the driving force of the resistive wall
instability depends critically on the batch length for
constant local density.
