The in­ter­na­tion­al Muon Ion­iza­tion Cool­ing Ex­per­i­ment (MICE) will carry out a sys­tem­at­ic in­ves­ti­ga­tions of ion­iza­tion cool­ing of a muon beam. As the emit­tance mea­sure­ment will be done on a par­ti­cle-by-par­ti­cle basis, a so­phis­ti­cat­ed beam in­stru­men­ta­tion is need­ed to mea­sure par­ti­cle co­or­di­nates and tim­ing vs RF. A PID sys­tem based on three time-of-flight de­tec­tors, two Aero­gel Cerenkov coun­ters and a KLOE-like calorime­ter has been con­struct­ed in order to keep beam con­tam­i­na­tion (e, π) well below 1 %. The MICE TOF sys­tem will mea­sure tim­ing with a res­o­lu­tion bet­ter than 60 ps per plane, in a harsh en­vi­ron­ment due to high par­ti­cle rates, fringe mag­net­ic fields and RF back­grounds. Per­for­mances in beam of all de­tec­tors will be shown, as also fu­ture up­grades.

In the Muon Ion­iza­tion Cool­ing Ex­per­i­ment (MICE) at RAL muons are pro­duced and trans­port­ed in a ded­i­cat­ed beam­line con­nect­ing the pro­duc­tion point (tar­get) to the dif­fus­er, a mech­a­nism in­side the first spec­trom­e­ter solenoid de­signed to in­flate the ini­tial nor­mal­ized emit­tance up to 10 mm rad in a con­trolled fash­ion. In order to match the in­com­ing muons to the down­stream ex­per­i­ment, cov­er­ing all the pos­si­ble val­ues of the emit­tance-mo­men­tum ma­trix, an op­ti­mi­sa­tion pro­ce­dure has been de­vised which is based upon a ge­net­ic al­go­rithm cou­pled to the track­ing code G4Beam­line. De­tails of beam­line tun­ing and ini­tial mea­sure­ments are dis­cussed.

The Muon Ion­iza­tion Cool­ing Ex­per­i­ment is one lat­tice sec­tion of a cool­ing chan­nel suit­able for con­di­tion­ing the muon beam at the front end of a Neu­tri­no Fac­to­ry or Muon Col­lid­er. Scin­til­lat­ing fibre spec­trom­e­ters and 50 ps res­o­lu­tion tim­ing de­tec­tors pro­vide the un­prece­dent­ed op­por­tu­ni­ty to mea­sure the ini­tial and final six-di­men­sion­al phase space vec­tors of in­di­vid­u­al muons. The ca­pa­bil­i­ty of MICE to study the evo­lu­tion of muon beams through a solenoidal lat­tice will be de­scribed.
