The design of a future multi-TeV muon collider needs new ideas to overcome the technological challenges related production, cooling, accumulation and acceleration. In this paper layout positron driven source known as Low EMittance Muon Accelerator (LEMMA) concept is presented. beam, stored in ring with high energy acceptance low emittance, extracted multi-target system, produce pairs at threshold.

The muon collider represents one of the most promising solutions for a future machine exploring high energy frontier, but several challenges due to 2.2 $\mu$sec lifetime at rest have be carefully considered. LEMMA project is investigating possibility producing low emittance muon/antimuon pairs from e$^+$e$^-$ annihilation process threshold energy, resulting in small transverse beams without any additional beam cooling. However measurements available are performed higher $\sqrt{s}$ values. It...

A beam is obtained from e$^+$ e$^-$ → μ$^+$ μ$^-$ annihilation process at threshold energy 45 GeV eliminating need dedicated cooling system. series two testbeam campaigns were carried out CERN to validate this concept. The setup presented together with first preliminary results data.

An ultra high position resolution cavity BPM was developed for the final focus system of ATF2, which is a accelerator test facility ILC [1]. The main purpose ATF2 are achievement 37 nm beam size and nano-meter orbit stability at IP(Interaction Point). For these purposes, few nano meter required this BPM, called low-Q IP-BPM [2]. Three IP-BPMs were fabricated, first block consists two cavities in one second single cavity. Low-Q can measure vertical horizontal independently by using...
