The files G4Buncher*.out and G4PhaseRot*.out contain the kinematic information
of a muon beam at the end of the a GEANT4 simulation of the "Neuffer" buncher 
and phase rotator, respectivelly. The input beam to the buncher was originally 
generated with MARS, and had previously gone through 99m of a drift section.

The files are NOW IN ICOOL FORMAT. 

For more info about the buncher and phase rotator designs, see MuCool note
appearing in the near future (see Daniel Elvira's Shelter Island talk, and
Nancy Keuss's simulation meeting talk on Tues 13th of August).


There are three different buncher schemes:

G4Buncher60f.out   contains the beam out from a 60m buncher with 60 r.f.
                   cavities (one per meter) all with different frequencies.
                   The frequency is reduced as a function of z-position along
                   the buncher to compensate for the growth of the beam length.
	           Note that the file is a snapshot of the beam at z=60m
                   from the buncher origin.
                     
G4Buncher20f.out   Idem. The buncher is still 60m long and there are 60 
                   cavities (one per meter) but the frequency is changed every
                   three cavities, to reduce cost. Note that the file is a 
	           snapshot of the beam at z=58m from the buncher origin.

G4Buncher10f.out   Idem. The buncher is still 60m long and there are 60 
                   cavities (one per meter) but the frequency is changed every
                   six cavities, to further reduce cost. Note that the file is
                   a snapshot of the beam at z=55m from the buncher origin.


There is only one phase rotator scheme (fixed frequency), but three different 
possible outputs, associated with the use of the three different bunchers:

G4PhaseRot60f.out  contains the beam out from a 9m phase rotator, which
                   previously went through the 60 freq buncher. 
                   The z-location of the beam is 9m (meaning 9m from the 
                   phase rotator origin).
                     
G4PhaseRot20f.out  contains the beam out from a 9m phase rotator, which
                   previously went through the 20 freq buncher. 
                   The z-location of the beam in the file is 11m, measured
                   from the z-location of the G4Buncher20f.out beam. The 11m
                   therefore include 2m of drift (from 58m to 60m) and the 
                   9m of the phase rotator.
                   
G4PhaseRot10f.out  contains the beam out from a 9m phase rotator, which
                   previously went through the 10 freq buncher. 
                   The z-location of the beam in the file is 14m, measured
                   from the z-location of the G4Buncher10f.out beam. The 14m
                   therefore include 5m of drift (from 55m to 60m) and the 
                   9m of the phase rotator.
