We are developing a beam line which compresses the phase space of a standard surface μ+ beam by 10 orders of magnitude with an efficiency of 10−3. Phase space compression occurs in a He gas target and consists of three consecutive stages: Transverse (perpendicular to the beam axis) compression, longitudinal compression and re-extraction into vacuum. Transverse compression was observed for the first time and longitudinal compression has been measured to occur within 2.5 μs with high efficiency.
