+This is a driver for the detector tower which is based on the Turbo PMAC driver (https://gitea.psi.ch/lin-epics-modules/turboPmac). It consists of the following four objects:
 - `detectorTowerController`: This is an expanded variant of `turboPmacController` provided by the Turbo PMAC library linked above.It is needed to operate a `detectorTowerAngleAxis`, but it can also be used to operate a "normal" `turboPmacAxis`.
 - `detectorTowerAngleAxis`: This is a virtual axis which controls multiple physical motors ($x$ and $z$) in order to provide a combined movement. Moving it results in a rotation of the entire beam around the support axis position ($\alpha$).
 - `detectorTowerLiftAxis`: This is a virtual axis which controls multiple physical motors in order to provide a combined movement. Moving it results in a vertical lift ($z_{lift}$).
