Particle Loading Parameters
ILDPSI
Indices of the Hammersley sequence bases for loading the particle phase. GENESIS 1.3 uses the first 26 prime numbers as bases. To avoid correlation between the variables each base should be different.
ITGAMGAUS
Defines distribution profile in energy. A nonzero value generates a Gaussian distribution and a uniform otherwise.
INVERFC
When set to a nonzero value, the inverted error function is used for generating a Gaussian distribution instead of the jointpropability method. It results in smoother distribution in energy and transverse dimensions.
IPSEED
Initial seed for the random number generator used for particle phase fluctuation (shot noise). GENESIS 1.3 requires a reinitialization of the random number generator to guarantee the same loading whether magnetic field errors are used or not.
NBINS
Number of bins in the particle phase. The value has to be at least 4 or larger than (2+2n), depending on whether the bunching at the nth harmonics is needed for space charge calculations or output.
