Dear Yves,

I have some small remarks still to your slides.

slide 4:
I don't think it is true it is mainly protons which go to the CDC.

it is not clear to me what the points path  length and energy deposition
should indicate. if you want to say that that is what is measured, than
that is really obvious if I do dE/dx ;)

the 3rd item Need:
hm, this numbers really fall from heaven here, they have especially no
relation to anything before.
Especially the sigma_z is difficult, because i think we show not one plots
which proofs that we reach this and what it does on the physics.
I would also rename it to performance Goals. Actaully the whole slide is
better titled like that.

slide 6:
I think that remark is more for curtis, crystal Barrel was a nice
experiment, but like E852 stopped data taking last century ;) Is this
really the best comparision to make.
How about to look here http://www-panda.gsi.de/auto/_home.htm
and the wasa experience.

slide 19, I still think this slide is slightly misplaced, either it should
go infront of the safety slide or actually to the prototype, because there
you use it.


cheers elke
