Precision experiments with pions and muons

Oral

The muon capture experiment MuCap uses a negative muon beam stopped in a time projection chamber as an active target filled with ultra-pure hydrogen gas. The elementary capture process mu- +p-> n+nu offers a rare (0.15%) but additional disappearance channel. The measured difference of the positive and negative muon's lifetime determines the rate of the capture process to a final precision of...

1. Muon lifetime measurement with the FAST detector at PSI

Precision experiments with pions and muons

Oral

The Fibre Active Scintillator Target (FAST) experiment at the Paul Scherrer Institute is designed to measure the $\mu^+$ lifetime to 4 ps precision and thereby to determine the Fermi coupling constant, $G_F$, to 1 ppm. In FAST, a $\pi^+$ beam is stopped inside a highly granular target which images the entire $\pi^+\rightarrow \mu^+\rightarrow e^+$ decay chain. To achieve the high statistics...

62. MuSIC: A new DC muon beamline at RCNP

Dr Akira Sato (Osaka University)

Advanced muon sources

Oral

A new DC muon source is under construction at Research Center of Nuclear Physics (RCNP), Osaka University. The ring cyclotron of RCNP can provide 400W 400MeV proton beam. Using this proton beam, the MuSIC produces a high intense muon beam. The target muon intensity in 10^8 muons/second, which is achieved by a pion capture with great efficiency to collect pions and muons using a solenoidal...
