The CGEM-IT, an innovative Cylindrical GEM Inner Tracker, is the Italian proposal for the upgrade of the inner multilayer drift chamber of the BESIII experiment. The tracker consists of three independent layers, each with three multiplication stages. The strict requirements for resolution, size, and radiation length, as well as the need to withstand intercontinental shipping, require the use of advanced lightweight materials and state-of-the-art construction techniques. The construction of the innermost layer of the tracker is described in its entirety: from quality controls of the materials to assembly, which is accomplished with a custom vertical insertion machine.

Abstract
The CGEM-IT, an innovative Cylindrical GEM Inner Tracker, is the Italian proposal for the upgrade of the inner multilayer drift chamber of the BESIII experiment. The tracker consists of three independent layers, each with three multiplication stages. The strict requirements for resolution, size, and radiation length, as well as the need to withstand intercontinental shipping, require the use of advanced lightweight materials and state-of-the-art construction techniques. The construction of the innermost layer of the tracker is described in its entirety: from quality controls of the materials to assembly, which is accomplished with a custom vertical insertion machine.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
