P1	Institut Laue-Langevin (Co-ordinator)
	ILL is the world’s leading facility in neutron science which operates the most intense neutron source on Earth. It initiated the 3He neutron spin filter project more than 12 years ago and has co-ordinated or participated in several EC R&D networks including NSF projects. It operates two generations of 3He filling stations (MEOP) and several types of 3He containers and magnetostatic cavities for carrying out routinely scheduled neutron scattering experiments. Today, ILL is world-recognised as the most experienced neutron centre in this field.

	The Neutron Scattering Laboratory of the CEA-Grenoble has a world-recognised experience in polarised neutron scattering since its creation by Prof. L. Néel (Nobel prize) and Prof. E.F. Bertaut in the early 60’s. This laboratory has recently installed two CRG (Collaborative Research Group) instruments on the supermirror thermal guide H25 at the ILL: a two-axis diffractometer D23 with lifting arm detector, and a high-flux three-axis spectrometer IN22 dedicated to polarised neutron inelastic scattering studies. For the past few years, this laboratory has acquired much competence in polarising and analysing the neutron polarisation with 3He neutron spin filters within the framework of previous EC R&D networks (FP4-XENNI, FP5-ENPI). Among the many deliverables, one can cite the design and construction of a cryogenic magneto-static cavity Cryopol aiming to operate the NSF under high field, and the contribution to the construction of the 3He filling station Tyrex recently installed at the ILL.

	FZJ is active with both SEOP and MEOP. This was the first group to introduce the Yb fibre Laser as a replacement for LNA in MEOP for the production of NSF and now this has become the standard Laser for the task. The group was the first to begin study of K as the alkali metal for SEOP, following up on promising experiments including one of the group’s members.

P4	Hahn-Meitner Institut
	HMI with its upgraded research reactor BERII operated by BENSC (Berlin Neutron Scattering Centre) is one of the best and most widely used neutron sources in Europe. Research with polarised neutrons plays a substantial role in its scientific programme and thus, there is a great interest to apply 3He neutron spin filter at various instruments, like the triple-axis spectrometer E1, the SANS instrument V4, the reflectometer V6, and others. Therefore, the development of suitable and reliable 3He spin filter cells and of equipment to supply and to handle them is one of the institute’s essential efforts. Supported by the European Commission during former networks (XENNI, ENPI, Cool Neutron Project), HMI gained wide experience in all fields related to this technique: a filling station to provide filter cells with polarised 3He has been developed and is under construction in close collaboration with P3. HMI works on the preparation of Cs coated quartz glass cells, actually with P1 and had already performed first neutron experiments with them, yielding reasonable results. Finally, magnetic chambers to keep the filter cells in an indispensable, homogeneous magnetic field during both, transportation and use, have been realised.

P5	CCLRC/RAL/ISIS Facility
	ISIS is presently the world’s brightest pulsed neutron and muon source situated at the Rutherford Appleton Laboratory. CCLRC focusses on developing a prototype system for instruments on pulsed sources together with the observers. The priority is to develop and build prototype systems that can run continusously, sometimes under difficult magnetic environments with minimum intervention fromt the users. CCLRC participates in all tasks and provide a test bed for the use of high energy neutrons and time-of-flight techniques.

	FRM-II is going to acquire a polarised 3He filling station (MEOP) with the aim to take advantage of the 3He neutron spin filters on six instruments: PUMA, PANDA, HeiDi, MSREF, Particle Physics Facility and MIRA.
