The cylindrical drift chamber is the most innovative part of the MEG~IIdetector, the upgraded version of the MEG experiment. The MEG~II chamberdiffers from the MEG one because it is a single volume cylindrical structure,instead of a segmented one, chosen to improve its resolutions and efficiency indetecting low energy positrons from muon decays at rest. In this paper, we showthe characteristics and performances of this fundamental part of the MEG~IIapparatus and we discuss the impact of its higher resolution and efficiency onthe sensitivity of the MEG~II experiment. Because of its innovative structureand high quality resolution and efficiency the MEG~II cylindrical drift chamberwill be a cornerstone in the development of an ideal tracking detector forfuture positron-electron collider machines.

Abstract
The cylindrical drift chamber is the most innovative part of the MEG~IIdetector, the upgraded version of the MEG experiment. The MEG~II chamberdiffers from the MEG one because it is a single volume cylindrical structure,instead of a segmented one, chosen to improve its resolutions and efficiency indetecting low energy positrons from muon decays at rest. In this paper, we showthe characteristics and performances of this fundamental part of the MEG~IIapparatus and we discuss the impact of its higher resolution and efficiency onthe sensitivity of the MEG~II experiment. Because of its innovative structureand high quality resolution and efficiency the MEG~II cylindrical drift chamberwill be a cornerstone in the development of an ideal tracking detector forfuture positron-electron collider machines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
