Data acquisition system for the MuLan muon lifetime experiment
V. Tishchenko, S. Battu, S. Cheekatmalla +8
We describe the data acquisition system for the MuLan muon lifetime experiment at Paul Scherrer Institute. The system was designed to record muon decays at rates up to 1 MHz and ac…
Detailed Report of the MuLan Measurement of the Positive Muon Lifetime and Determination of the Fermi Constant
V. Tishchenko, S. Battu, R. M. Carey +30
We present a detailed report of the method, setup, analysis and results of a precision measurement of the positive muon lifetime. The experiment was conducted at the Paul Scherrer…
KOSMOS and COSMOS: New facility instruments for the NOAO 4-meter telescopes
Paul Martini, J. Elias, S. Points +19
We describe the design, construction and measured performance of the Kitt Peak Ohio State Multi-Object Spectrograph (KOSMOS) for the 4-m Mayall telescope and the Cerro Tololo Ohio…
Effect of cobalt substitution on structural, impedance, ferroelectric and magnetic properties of multiferroic Bi_2Fe_4O_9 ceramics
S. R. Mohapatra, B. Sahu, M. Chandrasekhar +4
Structural, impedance, ferroelectric and magnetic properties were examined in multiferroic Bi_{2}Fe_{4(1-x)}Co_{4x}O_{9} (0x0.02) ceramics synthesized via solid-state r…
Measurement of the Positive Muon Lifetime and Determination of the Fermi Constant to Part-per-Million Precision
D. M. Webber, V. Tishchenko, Q. ~Peng +30
We report a measurement of the positive muon lifetime to a precision of 1.0 parts per million (ppm); it is the most precise particle lifetime ever measured. The experiment used a t…
Improved Measurement of the Positive Muon Lifetime and Determination of the Fermi Constant
MuLan Collaboration, D. B. Chitwood, T. I. Banks +38
The mean life of the positive muon has been measured to a precision of 11 ppm using a low-energy, pulsed muon beam stopped in a ferromagnetic target, which was surrounded by a scin…
