NA62 Spectrometer: A Low Mass Straw Tracker

The NA62 experiment at CERN, aiming at a precision measurement of the ultra-rare decay K + → π + νν, relies on kinematical rejection up to 10 5 (≈ 10 12 is needed in total). One of the limiting factors to achieve this goal is the multiple scattering in the magnetic spectrometer for kaon decay produc...

description The NA62 experiment at CERN, aiming at a precision measurement of the ultra-rare decay K + → π + νν, relies on kinematical rejection up to 10 5 (≈ 10 12 is needed in total). One of the limiting factors to achieve this goal is the multiple scattering in the magnetic spectrometer for kaon decay products; therefore an almost massless (≈1.5% X0) straw tracker has been designed to operate in vacuum, to be able to install it inside the decay volume. A vacuum tight prototype was built and tested in 2010: efficiency (≈99%), rate capability and single straw resolution (≈200 μm) were verified. The construction of the first chamber started in 2011.
