Hi All,

Has anyone made a user defined distribution that is shaped like a triangle?

Or any other shape besides a Gaussian?

I'd like to make an input distribution that is triangular in the longitudinal dimension.

Should I start with a Gaussian and apply a filter/cut?

​Is there a standard way of doing this for arbitrary shapes?

This seems somewhat related to the collimator discussion that was going on.

However, now I want to manipulate the longitudinal profile instead of transverse.

Maybe I could make the distribution I want in the transverse, then transpose it to the longitudinal?

I'm using OPAL-T v1.9.

Thanks in advance,

Nicole
