	IUCF is working on a two-stage piston compressor and on the application of 3He neutron spin filters to neutron reflectometry at the POSY instrument at IPNS (Intense Pulsed Neutron Source). IUCF has experience in magnetic shielding of 3He analysers on POSY at IPNS.

	NIST has a very long experience in SEOP and has developed a compact diaphragm compressor for MEOP. The group of Dr. T.R. Gentile also manufactures long relaxation time 3He containers for both techniques (MEOP and SEOP) and has already loaned two SEOP cells to P5. The 3He neutron spin filter is applied to reflectometry and small angle neutron scattering at the NIST Center for Neutron Research (NCNR).

O3	ORNL, Spallation Neutron Source
	The Spallation Neutron Source (SNS) is an accelerator-based pulsed neutron source under construction in Oak Ridge, Tennessee, USA. This project is a collaboration of six National Research Laboratories under the stewardship of the U.S. Department of Energy. The SNS will provide the most intense pulsed neutron beams in the world for scientific research and industrial development. Dr. C. Hoffmann is in charge of the design and construction of a single crystal diffractometer with provisions for neutron polarisation analysis. Current polarisation techniques for the white spectrum of pulsed neutron sources are in a prototypical state.

	KEK has been working on SEOP since around 1990. Development of mono-crystalline cells and crystalline coated quartz glass cells is recently pursued. A test experiment with SEOP NSF on a reflectometer PORE at KENS (KEK NeutronScience Laboratory) is being prepared.

	The University of Michigan Laser Polarized Noble gas group, led by Professor Timothy Chupp and Dr. Kevin Coulter, has long been committed to the development and applications of polarised 3He neutron spin filters. In 1986, they first proposed the use of gaseous 3He produced by spin exchange as a broad band spin filter and by 1989 they had completed the first successful experiment with polarised epithermal neutrons at the Los Alamos Spallation Source. They also collaborated on the first experiments at ILL that used a small sample of gaseous 3He polarised by spin exchange. Since then, They have contributed to the tremendous advances in 3He polarisation techniques and applications, developing targets for electron scattering and for nuclear physics measurements. They have developed the "spin exchange COW" that is used to fill high quality valved neutron spin filter cells with 3He at 50% polarisation, which is expected to be improved with this effort. Continued advances of 3He polarisation by spin exchange, a crucial component of these efforts, will be of major importance to this project. They introduced high powered laser diode arrays to 3He polarisation and developed the first narrowed arrays for Rb pumping. Single mode operation of narrowed arrays has been achieved. They will also contribute to design efforts crucial for specific applications as this technology is transfered to neutron scattering instruments. Their expertise on neutron spin transport will be valuable to the development of magnetic cavities in the scattering instruments.
