PTC_SETSWITCH

SYNOPSIS

PTC_SETSWITCH,
debuglevel = [i,0], 
maxacceleration = [l, true, true],
exact_mis = [l, false, true],
totalpath = [l, false, true],
radiation = [l false, true],
fringe = [l, false, true],
time = [l, true, true];

Command parameters and switches

debuglevel

integer, default value 1, no default value if value explicitly not specified

Sets the level of debugging printout 0 none, 4 everything

maxacceleration

logical, default true, if value explicitly not specified then true

Switch saying to set cavities phases so the reference orbit is always on the crest, i.e. gains max energy

exact_mis

logical, default false, true if value explicitly specified

Switch ensures exact misalignment treatment.

totalpath

logical, default false, true if value explicitly specified

If true, the 6th variable of PTC, i.e. 5th of MAD-X is the total path. If false it is deviation from the reference particle, which is normally the closed orbit for closed layouts.

radiation

logical, default false, if value explicitly not specified then true:

Sets the radiation switch/internal state of PTC.

fringe

logical, default false, true if value explicitly specified:

Sets the fringe switch/internal state of PTC. If true the influence of the fringe fields is evaluated for all the elements.

Please note that currently fringe fields are always taken to the account for some elements (f.g. traveling wave cavities) even if this flag is set to false. The more detailed list of the elements will be provided later, when the situation in this matter will be definitely settled.

time

logical, default true, if value explicitly not specified then true :

If true, Selects time of flight rather than path length. (cT to be precise) as the 6th variable of PTC, i.e. 5th of MAD-X.
