Collimator wakes

[Adam_Dixon]

Hi,

I have set up simulations in which I am collimating the bunch at a dispersive section in a bunch compressor, using the 'scraper' element. I would like to include the wakefield effects from the collimator in the simulations. Is this possible in elegant?
I see that there is no mention of wakes for the 'scraper', 'ecol' or 'rcol' elements in the manual, but maybe there is another element that would work.

Thanks,
Adam
