Introduction

The design of a high power neutrino source based on muon storage rings is underway. A summary of a Fermilab based facility has been written, and work is proceeding on a second iteration, which should produce more neutrinos and cost less. Both studies are predicated on the idea that ionization cooling of muons is practical and cost effective.

Theoretical work on the design of these muon cooling systems has been done for a number of years and an experimental demonstration is being designed. There are a number of relevant notes and articles describing different aspects of this work. A meeting at CERN identified problems and discussed many of the relevant technologies. Most of the known problems have been described in the first meeting at CERN, and more detailed information is available from the references below.

The purpose of this meeting is to discuss practical instrumentation for the muon cooling experiment and study instrumentation problems for the neutrino source.

The cooling instrumentation must measure the distribution of muons in the presence of backgrounds from the target and from the rf cavities.

Other beam instrumentation problems include the measurement of the muon polarization at low energies in an intense beam, and monitoring the operation of the high power target and the target solenoids.
