A new cylindrical drift chamber is currently under construction for the MEG II experiment. The chamber is meant to track low momentum positrons from mu(+) decays to search for mu(+)-> e(+)gamma events. The detector is segmented in very small drift cells, placed in stereo configuration and operated in a helium-isobutane gas mixture. The use of thin aluminium wires and light gas mixture set the total radiation length of the chamber to only 1.6 x 10(-3)X(0) per track turn allowing for a momentum resolution of similar to 120 keV/c.

Abstract

A new cylindrical drift chamber is currently under construction for the MEG II experiment. The chamber is meant to track low momentum positrons from mu(+) decays to search for mu(+)-> e(+)gamma events. The detector is segmented in very small drift cells, placed in stereo configuration and operated in a helium-isobutane gas mixture. The use of thin aluminium wires and light gas mixture set the total radiation length of the chamber to only 1.6 x 10(-3)X(0) per track turn allowing for a momentum resolution of similar to 120 keV/c.
