Descriptions of various research communities anticipated needs for ARIF, as described by disciplinary societies, are excerpted below:

Chemical Physics

“As research instrumentation grows more complex and more expensive, we envision many individual research labs encroaching on the lower end of this instrumentation limit. For example, in the next few years, ultrashort extended UV and x-ray sources, various UHV surface analysis tools, and ultra-high-field NMR spectrometers should become available commercially and individual investigators will want to have such costly equipment in their labs. There is also the need for tunable free-electron lasers and linear accelerators applicable to QED research.

At the same time, there are various types of equipment that can only exist in shared facilities, such as equipment with a >$10M pricetag. As the SNS goes online at Oak Ridge, there are many instruments associated with this source that should be built. The SNS has the potential to be the premier neutron diffraction facility in the world with its predicted high neutron fluxes. This is one piece of instrumentation that should be a VERY high priority because it would be unique and would bolster the US presence in this internationally dominated field.

Computing architectures will continue to be in high demand in the future. We can anticipate new architectures becoming available (e.g., vector processors rather than massively parallel scalar processors). Another important component for the usability of these high-end computer systems is the availability of software for specific applications. There is the need for significant investment in the software as well as the hardware for high-performance computing systems. Limited funding drives the need for development of shared software (community codes) as well as shared hardware.

“One would be a cyclotron-based mass spectrometer, which would be very useful for high-throughput, high-accuracy proteomics. Another would be a computer cluster of appropriate size. It is possible that instrumentation starting in this price range will drop in cost as the market develops. These two items would be very useful in the future of genomics and its attendant -omic disciplines. There
