Dear All

as preparation for todays IR meeting and the topic on final tables. 

In https://www.dropbox.com/sh/18xyg8jcni18dk2/AADGDe_bFw_kzSMR3xATegpGa?dl=0

I have collected the files I got from Steven and Guillaume 

I also wrote a summary (eRHIC.IR.Simulations.docx in the same directory) on what I think I understood is going into the files.

I have a couple of questions and requests,

Can we please include in the data and survey file the beam energy for which this file was generated

Further I got this equations home to calculate the field and gradients  for the dipoles and quads, respectively.

I just need B_rho to go from one to the other energy. Is this absolutely correct, because last time there was some discussion I could not follow about vertical focussing quads.

I would appreciate a clear statement on this.

Table 3 and 4 in https://www.dropbox.com/s/pkialtwg8vnfjoz/master.IR.pdf?dl=0 

have the inner radii needed for the apertures 

Some questions: 

is the 20 mrad for Q2PF correct?

only Q1ER and Q2ER are actually rotated around the beam all other magnets look not rotated to me, is this correct?

I think it would be good to include in table for B1ER and B2ER

I invite everybody to give me feedback on the description of the files, so it can be made really complete and hopefully used by everybody who needs this information now and in the future.

Thanks

elke
