| The radiation length for the complete detector from eta=0-2.0 and phi=0-6.28 The outside peaks are larger because of the blocks (SSLB, SSLT) which are at the position of the ladder | The radiation length for the complete detector from eta=0-2.0 and phi=1.1-2.1 The picture shows nicely, that the radiation length of one ladder is 1%. (See upper left picture) |

| In this picture the holder of the ladders are excluded (SSST, SSSS, SSRT, SSRS) So there is no background in the intermediate region | In this picture the holder of the ladders (SSST, SSSS, SSRT, SSRS) and the blocks and pipes are excluded (SSLB, SSLT) So there is no background in the intermediate region |
