Superconducting solenoids for the MICE channel

Proceedings of the IEEE Particle Accelerator Conference 3 (2003) 1987-1989

Authors:

MA Green, G Barr, DE Baynham, JH Rockford, P Fabbricatore, S Farinon, RB Palmer, JM Rey

Abstract:

This report describes the channel of superconducting solenoids for the proposed international Muon Ionization Cooling Experiment (MICE). MICE consists of two cells of a SFOFO cooling channel that is similar to that studied in the level 2 study of a neutrino factory[1], MICE also consists of two detector solenoids at either end of the cooling channel section. The superconducting solenoids for MICE perform three functions. The coupling solenoids, which are large solenoids around 201.25 MHz RF cavities, couple the muon beam between the focusing sections as it passes along the cooling channel. The focusing solenoids are around the liquid hydrogen absorber that reduces the momentum of the muons in all directions. These solenoids generate a gradient field along the axis as they reduce the beta of the muon beam before it enters the absorber. Each detector solenoid system consists of five coils that match the muon beam coming to or from an absorber to a 4.0 T uniform solenoidal field section that that contains the particle detectors at the ends of the experiment. There are detector solenoids at the beginning and at the end of the experiment. This report describes the parameters of the eighteen superconducting coils that make up the MICE magnetic channel.

Abstract:

A search for the decay KS → π0γγ has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity KS beam, an upper limit for the branching ratio BR(KS → π0γγ, z ≥ 0.2) < 3.3 x 10-7 has been obtained at 90% confidence level, where z = m2γγ/mKO2. © 2003 Published by Elsevier Science B.V.
