Attached are all the pocket geometries available behind the electron cooler in ESR. We have 4 different detector drives there, each with a different shape/length of its pocket.

The 1st drive behind the cooler is about 10m away (to be checked) and equipped with a long (796mm) pocket of style "rect" and an stepper motor. Status of drive: unknown.

2nd drive is the extra long one at the end of the dipole (~15m behind cooler). It is equipped with a "long_drive" pocket and features a stepper and compressed air mode. Status of drive modes: unknown

3rd drive is a standard (530mm) "rect" style pocket inside a compressed air drive located about 20m behind the cooler. Status of drive as of 2024: no reliable positioning. But bearings have been renewed recently (12.2025) and we shall test it again.

4th drive is an old stepper motor featuring an old "round" style pocket. Location is behind the second dipole in south arc (30m ?). Status of drive: unknown
