What is recorded here?
The muCool team demonstrated separate longitudinal and transverse compression stages for positive muons stopped in helium gas. Bao and colleagues used electric fields to concentrate the stopping distribution along a magnetic field. Antognini and colleagues later used a cryogenic density gradient and crossed fields to obtain transverse convergence. Decay-positron time spectra, control conditions and collision simulations supported both demonstrations. The inferred final sizes and compression times were obtained through those models rather than direct complete beam tomography.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The two experiments tested separate stages under different gas and injection conditions. Their proposed combined ten-order phase-space improvement required subsequent integration, extraction and reacceleration. Small final dimensions, efficiencies and momentum spreads include simulation assumptions, decay losses, detector acceptance and fitted alignment or impurity effects. This family does not establish a completed six-dimensional cooling and acceleration chain or directly measured universal compression factors.
