The future prospects of muon colliders and neutrino factories

The potential of muon beams for high energy physics applications is described along with the challenges of producing high quality muon beams. Two proposed approaches for delivering high intensity muon beams, a proton driver source and a positron driver source, are described and compared. The proton driver concepts are based on the studies from the Muon Accelerator Program (MAP). The MAP effort focused on a path to deliver muon-based facilities, ranging from neutrino factories to muon colliders, that could span research needs at both the intensity and energy frontiers. The Low EMittance Muon Accelerator (LEMMA) concept, which uses a positron-driven source, provides an attractive path to very high energy lepton colliders with improved particle backgrounds. The recent study of a 14 TeV muon collider in the LHC tunnel, which could leverage the existing CERN injectors and infrastructure and provide physics reach comparable to the 100 TeV FCC-hh, at lower cost and with cleaner physics conditions, is also discussed. The present status of the design and R&D efforts towards each of these sources is described. A summary of important R&D required to establish a facility path for each concept is also presented.Comment: 29 pages, 17 figure

Relationships of Self-Concept, Food and Nutrition Attitudes and Knowledge, and Health Habits to Food Selection and Nutrient Intake

To examine the relationships between self-concept and food- and nutrition-related behavior, information was collected from 153 single women ages 18-35. Participants were contacted through their places of employment and represented a variety of occupations. Each participant had an educational level between a high school diploma and a four-year college degree. Participants completed a questionnaire requesting information about demographic facts, attitudes toward self, attitudes toward the importance of food and nutrition, nutrition knowledge, and health habits. Each participant also completed a three-day food record. Factor analysis of the attitudes toward self, attitudes toward the importance of food and nutrition, and health habits variables yielded 14 meaningful factors. These factors and nutrition knowledge were evaluated for relationships with food selection and nutrient intake. Participants consumed \u3c75% of the Recommended Dietary Allowances (RDA) for energy, calcium, and iron and \u3e125% of the RDA for protein. Snacks were the source of about 17% of calories. Mean score on the 25-point nutrition knowledge test was 14.8 ± 3.6. Scores on one of the factors, Super Person (leader, self-confident, and aggressive) were negatively correlated with 5 of the 15 dietary components studied. Scores on Your Own Thing also were negatively correlated with several dietary components. Scores on the self-perception of a Traditional orientation to life factor (help others and work hard) and the self-perception of being Careful in other health areas factor were positively related to dietary patterns. Scores on the attitude that Nutrition Is Important factor and nutrition knowledge also were positively related to food consumption and nutrient intake
