The Advanced Photon Source 1-ID beamline, operating in the 40–140 keV X-ray energy range, has successfully employed continuously tunable saw-tooth refractive lenses to routinely deliver beams focused in both one and two dimensions to experiments for over 15 years. The practical experience of implementing such lenses, made of silicon and aluminium, is presented, including their properties, control, alignment, and diagnostic methods, achieving ∼1 µm focusing (vertically). Ongoing development and prospects towards submicrometre focusing at these high energies are also mentioned.

In spring and summer of 2008 and 2009, sawmill production capacity and utilization information was collected from major wood manufacturers in southeast Alaska. The estimated mill capacity in southeast Alaska for calendar year 2007 was 292,350 thousand board feet (mbf) (log scale), and for calendar year 2008 was 282,350 mbf (log scale).

In spring 2004 and 2005, sawmill capacity and wood utilization information was collected for selected mills in southeast Alaska. The collected information is required to prepare information for compliance with Section 705(a) of the Tongass Timber Reform Act. The total capacity in the region (active and inactive mills) was 370,350 thousand board feet (mbf) Scribner log scale during both calendar (CYs) 2003 and 2004. The capacity of active mills for the same periods was 255,350 mbf. This is a 7.4-percent increase in active capacity from CY 2002 (237,850 mbf) to CY 2004. The actual volume of material processed during CY 2004 was 31,027 mbf Scribner log scale. This is a 21.9-percent reduction over CY 2002 (39,702 mbf Scribner log scale).

In spring 2006 and 2007, sawmill capacity and wood utilization information was collected for selected mills in southeast Alaska. The collected information is required to prepare information for compliance with Section 705(a) of the Tongass Timber Reform Act. The total estimated design capacity in the region (active and inactive mills) was 289,850 thousand board feet (mbf) Scribner log scale in calendar year (CY) 2005 and 284,350 mbf in CY 2006. The estimated design capacity of active mills was 259,850 mbf for CY 2005 and 247,850 mbf for CY 2006. This is a 2.9-percent decrease in active design capacity from CY 2004 (255,350 mbf) to CY 2006.
