The design and construction of the large Drift Chamber for the KLOE experiment at the
Frascati φ-factory, DAΦNE, are described. The relevant aspects of the various elements of …

The performance of a small prototype of a cylindrical drift chamber (CDC) used in the
COMET Phase-I experiment was studied by using an electron beam. The prototype chamber …

The statistical advantages deriving from counting primary ionization, as opposed to the
conventional energy loss measurement, are extensively discussed. A primary ionization …

This report summarizes some useful data on the transport characteristics of gas mixtures
which are required for detection of charged particles in gas detectors. We try to replace …

An apparatus is described to measure drift velocities of electrons in gas mixtures. Free
electrons are liberated in the gas by laser ionization and the drift time is measured with a two …

Neutrons do not directly ionise the medium they pass through, unlike charged particles.
Neutron detection is then based on nuclear reactions in which the neutron is typically lost …

A method for measuring the electron drift velocity in working gas is proposed. Based on the
cathode and the anode signal waveforms of the Frisch-grid ionization chamber, the electron …

This paper reports the final results of an accurate and complete experimental study of the
performance of a large-area (1150× 566 mm2) planar drift chamber filled with a He …

The MEG-II experiment searches for the lepton-flavor-violating decay: μ⟶ e+ γ. The
reconstruction of the positron trajectory uses a drift chamber operated with a mixture of H e …

The single-electron longitudinal diffusion has been measured in several helium-isobutane
gas mixtures and compared with computations based on electron transport theories. A …
