Los Alamos National Laboratory Floodplain Assessment for the West Road Post and Cable Fencing Project

The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the U.S. Department of Energy (DOE), is proposing to take action at Los Alamos National Laboratory (LANL) to install post and cable or in-kind barriers along West Road at selected locations near the Los Alamos County ice-skating rink in Los Alamos Canyon (Figure 1). The proposed project is intended to improve vehicular and pedestrian safety on West Road by reducing traffic hazards associated with unsafe roadside parking and reduce wildland fire hazards associated with vehicles driving and parking on vegetation. West Road crosses approximately 0.35 miles (mi.) (1,900 feet (ft.)) of the Los Alamos Canyon floodplain at the bottom of Los Alamos Canyon. Project activities within the floodplain include blocking access to the informal roadside parking along either side of West Road in Los Alamos Canyon.

Peeking through the picket fence - What astrophysical surprises may be present in the 100-200 A region?

In anticipation of more sensitive EUV and FUV spectroscopic instruments, spectra are simulated including interstellar absorption of solarlike, RS CVn, and flare stars as folded through the instrument parameters of the EUVE, Lyman/FUSE Phase A, and a desirable next-generation spectrometer. Even the relatively insensitive EUVE spectrometer is able to detect sufficient spectral lines from many active binary and dMe stars to determine their coronal-emission-measure distributions. The Lyman/FUSE or next-generation spectrometers are needed to study solar-type stars or flaring stars with high time resolution. The high throughput and effective area of a nex-generation spectrometer is needed for Doppler imaging studies, stellar wind and downflow measurements, and high time and spectral resolution of stellar flares.
