Hi, all
I want to measure the beam emittance by pepper-pot. the accesory is my elegant files. when I run it ,I always be puzzled by a question,that is as follows:
I don't know where I'm wrong. my inital rms emittance is 1.25e-9, betax=5e-3, p_central=800, so the initial beam size is 2.5um. Is there any one can help me ? Thank you very much!
