ECCE Public Announcements

[Aschenauer Elke-Caroline <elke AT bnl.gov>]

Dear All,

we would like to announce a document summarizing a study how measurements at the EIC will be influenced by various accelerator and beam effects, i.e. the crossing angle,

the crabbing rotation, the beam energy spread, the angular beam divergence, and the bunch length. 
The accelerator and beam effects studied in the note need to be included in physics and detector simulations for the EIC. They can have profound consequences of the measurement capabilities of the EIC and the design and layout of the detectors. Of particular interest are, e.g., analysis of azimuthal modulations in the cross section that reveal insights on GPDs or TMDs and the possible fake asymmetries being caused by the accelerator and beam effects.

We provide code how to integrate these effect on generator level or as after burner, as well as a movie illustrating the electron and proton bunch movement during their interaction. 

The visualization is for an electron-proton collision at 18x275 GeV and based on the transport model described in the note.

You can find the note and movie at https://eic.github.io/resources/simulations.html and http://www.eicug.org/web/documents/public under technical notes.

Regards,
Alex, Brian, Elke, Jarda, Jin, Markus and Yulia
