- Page 138: The equation for the number of Bhabha per bunch-crossing must have something missing, otherwise it suggests order of thousands events per bunch crossing.
B. Schumm :True - the factor of 8 came from the integral alone, and did not include the pre-factor including the overall cross section scale, the lum, and the bunch-crossing rate. The new factor that replaces "8" is 6x10^{-6}. - Page 138: Theta_min is used in the formula, then as equal for 20 mrad (where it probably refers to the beamstrahlung envelope and not to LumiCal), then as equal to 3 mrad (that is the BeamCal, not LumiCal) after referring to systematic (geometric) errors. Please revise for consistency. Consider also starting the paragraphs below on BeamCal with a new section number.
B. Schumm :Yes - this was confused. Theta_min is now only used for the fiducial-region boundary, and is
always 46 mrad. I didn't agree with the statement about the new section number: it all belongs in
section 8.1.1 on overall design criteria. - Page 145 and following: The discussion of "stau" pair production as example of the relevance of BeamCal for vetoing two-photon background is interesting. However, as it is presented in chapter 8 it seems somewhat out of the style of the document, since other cases of this type are not discussed in the previous chapters, and the reader is expecting to see them collected together as physics studies. You might consider moving this case to that chapter – when it exists - and just refer to it in chapter 8.
