10
New this year more numerous affordable octahedra
Over 2000 octahedra minted (savings will be
36,000 when they are all used).
4 new molds made for injection-molding octahedra
and cubes.
11
Numerous affordable furnaces
These 3.50 laser-cut rhenium furnaces are stable
and their power curves are reproducible.
12
New ceramics
New batches of extruded ceramic pieces are in the
finished size, resemble pasta noodles, and the
cost is 50 cents per piece or even lower (shown
MgO, left, and forsterite, right).
13
New this year assemblies were calibrated at beam
lines and in-house, and further characterized
through extended use at several locations.
Were working on complete assemblies. Shown the
8/3, partially assembled.
14
New this year The Zirconia Problem.
Bad zirconia has temporarily wrecked our 14/8,
18/11 and 25/15 programs. We are now testing
extruded zirconia from a new source.
15
New this year In-situ assemblies
2. Not shown Forsterite or MgO sleeves outside
the furnace, and mullite octahedra - new, low-Z
combinations that work well! (Cubes being used
in the DIAs at Brookhaven and APS Hongbo Long
and others).
1. Shown Vertical windows in LaCrO3 sleeve (CNC
machining) with alumina window, and matching
slits in Re furnace (laser-cut). To be tested in
late July of this year.
16
Conclusions
We are figuring out how to make inexpensive and
reliable assemblies like we had originally hoped,
thanks to COMPRES.
More specialized/improved assemblies are now on
tap.
We need to solve the Zirconia problem soon!
