Re: Talk 2: v3
Hi Yves,
Here is a plot of the integrated radiation lengths in the CDC as a
function of radial distance from the beamline for 90 degree and 20
degree tracks. The ranges specified on the right of the plot indicate
the amount of material in the active area of the CDC only. The large
step at the end of the active area is due to the outer shell for the 90
degree case and the endplate for the 20 degree case. These were made by
averaging over 1000 events that were evenly distributed in phi so they
should represent a good average of the material.
You can have a look at this and the plot that Curtis has in his talk
of the CDC at only 90 degrees. If you would like something different
here, just let me know.
Regards,
-David
