Dear All,

Here are the first comments from the reviewer. Does anyone have a good 
answer to this?

Thanks,

Mark

Dear Dr. Slater,

Thank you for your recent submission to Nuclear Inst. and Methods in
Physics Research, A.

Before proceeding further with the review process, I would like you to
address in detail the following issue.  Beamstahlung will spread the
energy of the electrons and positrons at the collision point by an amount
far greater than the precision of the instrument that you propose. Indeed,
for the purposes of data analysis new approaches, such as particle flow
analysis, must be developed because one cannot balance momentum in the
beam direction. Your treatment of this issue should speak to how the
information from the proposed instrument would be used as an input to the
new physics analysis approaches.

Sincerely,

William A. Barletta
