Dear Users,

1. The next update, 1.0.8.22.1b will add a few new options for Emittance[]:
a) TRPT (=NORING) specifies calculation for a transport line, that ignores several parameters such as damping time, eigen modes, equilibrium emittance, etc. This mode is useful to evaluate the space charge effect ot intrabeam scattering in a transport line or a linac.
b) A new option InitialBeamMatrix -> bm specifies the beam matrix at the entrance as a 6 x 6 symmetric matrix. This is necessary for the TRPT calculation.
c) A new option Output -> fileno specifies the output file of the print out of EMITTANCE(EMIT) command. The default is 0, i.e. no output.

2. The EMITTANCE(EMIT) command automatically sets RING (=NOTRPT).

Dear Users,

1. The next version, 1.0.8.22.2b, will have one more bug fix on EMIT which did not calculate the effective voltage, momentum compactioin, etc. with NORADCOD probably since V1.0.8.21b.

Dear Users,

1. There were more bugs in the calculation of "effective voltage" in EMIT and transformation of CAVI and MULT with acceleration, so I fixed them in 1.0.8.22.1b1, but it is still not consistent with variaton of cavity phase exists. It will be fixed later.

Dear Users,

1. tfsetparam.f and tfphyz.f were changed to make internal consistency of a parameter "omega0", which is the angular revolution frequency, when MOMENTUM is changed dynamically. This could have caused some error in acceleration in CAVI, etc.

This was on V1.0.8.22.6b2. Sorry.

Dear Users,

1. The next version, 1.0.8.22.2b, will finally fix a very old bug on Linux and Darwin versions to skip the last line without linefeed at the end on reading (Get, etc.). This change does not affect the OSF1 version.

Dear Users,

1. Now the problem with effective voltage might be finally fixed. New variables at the MAIN level is newly defined:

DTSYNCH: shift of the origin of z of the closed orbit. (default: 0)
EFFVCRATIO: ratio of (effective voltage)/(Sum[VOLT_k,{k}]) (default: 1)
PHICAV: shift of cavity phase when variation exists for cavities. (default: 0)

These variables are set by EMIT and Emittance[]. In the case of TRPT, these values are reset to default.

The effective voltage is defined by

V_eff = Sqrt[(Sum[VOLT_k Cos[PHI_k],{k}])^2 + (Sum[VOLT_k Sin[PHI_k],{k}])^2]

and

PHICAV is chosen to satisfy

{Cos[PHICAV], Sin[PHICAV]} == {Sum[VOLT_k Cos[PHI_k],{k}], Sum[VOLT_k Sin[PHI_k],{k}]}

It was on V1.0.8.22.3b, not 1.0.8.23b.

Dear Users,

1. The change in EMIT and Emittance[] by 1.0.8.22.3b caused a bug to make it impossible to calculate for a negative momentum compaction case, as the stable rf phase is always shifted around zero. Now it is so corrected as to make the shift valid only when its magnitude is less than pi/2.
