Short-baseline opportunities and challenges at a neutrino factory

The exciting possibility of a neutrino source created by decays of muons in a storage ring has been proposed as a second-generation source for long-ba seline neutrino oscillation experiments. However, the enormous neutrino flu xes available at such a "neutrino factory" are also ideal for high-rate stu dies of neutrino interactions in detectors near the storage ring. I summari ze the parameters of likely near-detector experiments at a neutrino factory and discuss some of the physics opportunities possible at such facilities.
