Monte-Carlo simulation of Synchrotron Radiation power for the LHeC interaction region quadrupoles using SynRad+

The LHeC is in the design stage and various interaction region optics have been considered. The power emitted by the synchrotron radiation in the quadrupoles have been previously calculated by analytic and numerical methods. This note shows that SynRad+, a Monte-Carlo tool developed at CERN is a viable alternative for such calculations, and the initial learning curve might be shorter for users who are new to SR simulations. Moreover, results that are in good agreement with previous simulations are obtained on a desktop computer within seconds. This note presents an approximate calculation for comparison with previous results, and then a more complex and more accurate one.
