Particle Loading Parameters

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.

Hammersley base for loading the energy distribution. See ILDPSI for more information. Note that the loading of the energy distribution is Gaussian and uses two bases (ILDGAM and ILDGAM + 1).

Hammersley base for loading the distribution in x. See ILDPSI for more information.

Hammersley base for loading the distribution in y. See ILDPSI for more information.

Hammersley base for loading the distribution in p_x. See ILDPSI for more information.

Hammersley base for loading the distribution in p_y. See ILDPSI for more information.

Defines distribution profile in the transverse variables. The available distributions are:
- Gaussian (ITGAUS=1)
- Uniform (ITGAUS=2)
- Parabolic (otherwise)

Defines distribution profile in energy. A non-zero value generates a Gaussian distribution and a uniform otherwise.

When set to a non-zero value, the inverted error function is used for generating a Gaussian distribution instead of the joint-propability method. It results in smoother distribution in energy and transverse dimensions.

A non-zero value of IALL enforces that all slices are starting with the same element of the Hammersley sequences. It is recommend for time-dependent simulation excluding shot noise. IALL is set automatically for scans.

Initial seed for the random number generator used for particle phase fluctuation (shot noise). GENESIS 1.3 requires a re-initialization of the random number generator to guarantee the same loading whether magnetic field errors are used or not.

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.
