Author list : Could you please include James Jones in the list? James is now working with Graeme Burt et al on

              CLIC BDS tuning with crab system.

 

Table 1 caption : the distance from the nal ---> the distance from the final

 

Fig.1: not sure a=0.6 mrad on the figure is self explanatory? May be to mention it in 2.5.3 text?

 

Page 2, last para:

due to the tight constrains à due to tight constraints   (I am not so sure about this!!)

 

Page 3, third line from the top : Figure 2 à Fig.2

 

Section 2.5.3.3, first para

deigns à designs

 

Page 4 :

Lf for EAB in Javier note is 18 (and not 20).

The materials for betatron collimators and absorbers are not Ti in Javier\u2019s report!!

 

Fig.3. FFS optics does not show zero dispersion at the IP (assuming IP is at s=0)?

 

Full stop missing at the end of the page.

 

Section 2.5.3.6 :

Figure 4 à Fig.4

It would be good to give some description of crab cavity (at least frequency or some parameters) here, otherwise the figure here does not make any sense to me. Otherwise Figure could be included with the text in 2.5.5.3

 

Section 2.5.4 :

I would prefer biggest challenge to largest challenge.

 

Page 7 : first para, the appears twice on line 5th line from the top.

End of this section : Not clear what do you mean by \u201cThe two BDS lines should be optimized simultaneously\u201d? May be better to say electron and positron BDSs?

 

2.5.5 Magnets : should mention per BDS?

 

Page 9 : First line : Does anti-solenoid shields QD0 (I think compensation is probably the correct word?)

 

2.5.5.3 :

Crab specs : are they for 2% luminosity drop? May be worth mentioning when referring to phase and amplitude stability?

high à higher

 

2.5.5.4 :

Pressure better than 1 nTorr  (in what section not mentioned? )

The reference at the end of this section mentions à main Linac module, however the ref [21] seems to be CLIC quad vacuum chambers\u201d (I have not checked the ref itself!
