Positron driven muon source for a muon collider

Introduction

As far as the muon bunch intensity is concerned, the number of μ-μ+ pairs produced per positron bunch on target is:

n(μ+μ−)=n+ρ−lσ(μ+μ−)

The e+ e− →μ+ μ− cross section as a function of the positron beam energy is given in next figure.

Positron source

The e+ source has to provide trains of 1000 bunches with 5×10^11 e+/bunch to inject in the Damping Ring at 5 GeV.

Embedded Source

For each positron on the primary 3 mm Be target there are:

-0.11 photons | the W target

-0.65 e+ coming out of the 5×0 W target.

Beam parameters at the end of the embedded source capture channel are given in the following table.

Parameter Value
εn,y 7.9×10°3 mm mrad
E = 190 MeV
∆E 4.9×10°4 keV

Commento di Fausto C.
Devi rivedere un po' la sintassi della WiKi e, in particolare, il LateX ma per nel complesso va bene! Ti segno i 30m di lavoro a casa per aver completato la pagina!
