Sector
Viewing the Drift Chambers parallel to the beam line, in the x-y plane, the sector numbering runs 1-6 counter-clockwise starting at phi=0 degrees. Each sector is 60 degrees wide in phi, with sector 1 falling within the range -30 to +30 degrees in phi.
Superlayer
The drift chambers are divided into 3 diferent regions at around 2 meters for region 1, 3 meters for region 2, and 4 meters for region 3. Within each region, there are two superlayers, which are numbered sequential starting with 1 as the nearest to the target.
Layer
Each Superlayer is composed of 6 layers, numbered sequentially starting from nearest to furthest to the target.
Wire
Each layer has 112 wires, numbered sequentially from 1 to 112
