A simplified scheme for the provision of antiprotons at 100 MeV/c based on fast extraction is described. The scheme uses the existing p production target area and the modified Antiproton Collector Ring in their current location. The physics programme is largely based on capturing and storing antiprotons in Penning traps for the production and spectroscopy of antihydrogen. The machine modifications necessary to deliver batches of 1 u 10 7 p /min at 100 MeV/c are described. Details of the machine layout and the experimental area in the existing AAC Hall are given.

This paper reviews the recent performance of the AAC and LEAR. Activities on the AAC include the successful exploitation of a magnetic horn as an antiproton collector lens and an energy-saving mode of operation, which has been possible since 1992, when LEAR became the only client of the AAC. LEAR worked in its full momentum range between 100 MeV/c and 2 GeV/c, with performance (intensities, ejection modes and spill length) exceeding the design specifications. Improvements are described, which contributed to the quality of the beam delivered to experiments. The reliability and availability of the antiproton machines are also discussed.
Heat transfer through windows accounts for a significant percentage of a building's energy use and adds substantially to the peak cooling load of a home. Window covering manufacturers currently offer highefficiency insulated shades and motorized shading devices for certain product lines, but this automation is typically marketed as a convenience and security feature for the homeowner and often does not include energy-optimized control algorithms or dynamic and responsive features. This report describes the experimental design and results of testing the energy performance of Hunter Douglas double-cell cellular shades under various control schemes in the Pacific Northwest National Laboratory's (PNNL) Lab Homes. The results of both heating and cooling season experiments are presented. Tests were designed to assess the heating, ventilation, and air conditioning (HVAC) savings resulting from the thermal insulating properties as well as the automated and dynamic control strategies of shading devices. Control schemes tested included common "connected home" strategies where controls were integrated and coordinated between the window shading device, building thermostats, and external sensors.Experiments were specifically designed to examine persistence of savings with dynamic and potentially automated operation. To examine energy use and savings potential under typical use operational settings, a typical use scenario was developed based on previous residential behavioral research sponsored by the U.S. Department of Energy (DOE). The report also includes results from testing designed to examine the benefits (in terms of comfort, energy savings, and responsiveness to control) of coordinating the operation of cellular shades with HVAC control as a demand-response measure. Testing was conducted during both the 2017 and 2018 cooling and heating seasons.Some of the key findings for the cooling season are:• High-efficiency cellular shades have significant energy-saving potential during the summer cooling season (25% HVAC savings), but this savings decreases considerably if the larger view windows of a home remain uncovered during the day, particularly if these are west-or south-facing windows.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
