We have been hiring staff as fast as funds are released to us for that purpose. The cultural, archeological, geological and soil work is either on schedule or completed on the snowy acres that will shortly be our biggest research facility. Both the architect-engineering contract and the construction management contract have been signed with leading national firms. The first quadrapole magnet for guiding the positron beam has been shipped to Fermilab for testing. A prototype undulator, which will wiggle the positron beam to generate brilliant X-rays, has been designed by APS for testing at Brookhaven National Laboratory.
Testing continues on the aluminum vacuum chamber prototype.
And we are advancing development of a unique design to run liquid gallium through channels in the silicon crystals that act as polarizing mirrors for the X-ray beam, both to cool one side of the crystal and to heat the opposite side to offset distortion. I can't emphasize too much the importance of every discipline at Argonne getting ready to use APS in its own field of knowledge. We will be pleased if geologists, ceramists, metallurgists, chemists, physicists and biologists from other organizations and countries gain world renown through their work at the Advanced Photon Source. But we would prefer that Argonne people be the ones to do so. What looks like a flying saucer here is really the GLAD target area being moved into the IPNS complex for specialized neutron studies of glassy, liquid and amorphous materials.
