 ===== Cathode Readout Drift Chambers (CRDC) =====
-Two Cathode Readout Drift Chamber (CRDC) are used  to measure the transversal positions and angles in  the [[Stations#Focal Plane station|focal plane]]. The first detector (CRDC1) is located at the nominal optical focal plane, and it is separated 1 m from the second downstream detector (CRDC2).  Each detector has an active depth of 1.5 cm, an active area of 26 cm (non-dispersive direction) x 56 cm (dispersive direction), and [[Gas handling system|it is filled]] with a gas mixture consisting of 80% CF<sub>4</sub> and 20% C<sub>4</sub>H<sub>10</sub> at a typical pressure of 40 torr. The [[HV bias#CRDCs|operating high power]] depends on the charge of the measured nuclei. A schematic view of a CRDC can be seen in the figure below.

The detector frame has a volume of 68 cm (dispersive) x 38 cm (non-dispersive) x 10.3 cm (depth). The [[HV bias#CRDCs|operating high power]] depends on the charge of the measured nuclei. A schematic view of a CRDC can be seen in the figure below.
