Brief description of the Mirror Modules
There are two sets of mirror modules. The MM is designed as a conical approximation to the
Wolter I Xray telescope geometry. The outer diameter of the MMs are 600 mm and inner radius
is 82 mm. The focal length is 8000 mm. The MMs have each 143 laquered and AU-coated 0.4
mm thick Al-foils, nested to completely fill the opening. The design goal is an angular
resolution of 2 arcmin HPW.
The MM effective area and telescope parameters
are described below.
