some typical projects
neutron guide system @ HANARO, KAERI
For the initial equipment of the new HANARO neutron guide system about 180 m of guides were manufactured by SwissNeutronics. The guides start at the in-pile section with a complex super-unit comprising five individual guides. Out-of-pile the guides continue into the new neutron guide hall. Two of them branch into two sub-beams each. All guides are coated with supermirror m = 2 with an average reflectivity of R = 94% (measured on about 900 single substrates). The guides were delivered in various batches according the planning by KAERI, all in due time.

Focusing guide optic for TOPAZ @ SNS – truly curved non-linear tapering
The non-linear tapered guide for the beamline TOPAZ is the first neutron optics with supermirror coatings m = 5. This guide together with a special aluminum casing is manufactured and delivered by SwissNeutronics. Again the highly sophisticated coating technology of SwissNeutronics enabled for an excellent performance with reflectivity between 68 and 72% at the critical edge of the supermirror measured on all substrates. The non-linear tapered guide profile was developed by the customer and realized with the “truly curved” concept (continuous curvature) by SwissNeutronics.

Polarizing multi-channel V-cavity for KWS-1 @ FRM-II
The SANS instrument KWS-1 at FRM-II utilizes the concept of a V shape cavity to polarize the neutron beam. In order to realize this concept for the desired wavelength range and within the geometrical specifications (width, length), three parallel channels have to be assembled. Each channel is equipped with Si-wafer (t = 0.3 mm) in a V-shape geometry, coated with Fe/Si polarizing supermirror (m = 3.6). The device provides an average polarization of > 93%.

Metallic guide assembly for in-pile @ NIST
For the in-pile section of the new neutron guide system at the NCNR at the National Institute for Standards and Technology (NIST) decided to use the latest technology for metallic guides uniquely provided by SwissNeutronics. This guide assembly is located at a distance of about 1440 mm from the moderator. Since this region is subject to an increased thermal and radiation load, it was desired to fabricate it from aluminum substrates.
A complex geometry and various m-values from 1.2 to 3.6 were required to match the phase space of the subsequent neutron guides. The fabrication of the guide assembly was performed including the sophisticated super-polishing, supermirror coating with reflectivity measurements of all substrates and highly accurate assembly.

complex neutron guide assemblies for NIST
For the extension of their guide system the NCNR at the National Institute for Standards and Technology (NIST) in Gaithersburg, USA, required complex neutron guide assemblies for the initial section, close to the moderator. As usual, there the guides are very close to each other and NIST required large monolithic guide assemblies (super-units) for the best performance of the guides in this section. The super-units comprise several single guides with individual properties to transport the desired phase space. The neutronic design of the monoliths includes curved and elliptically tapered guides utilizing supermirror coatings on super-polished Borkron glass with appropriate m-values (up to m = 3.9).

Focusing monochromator system for HYSPEC @ SNS
The instrument HYSPEC at SNS uses crystal arrays to focus and direct the neutron beam onto the sample. Provision is made for arrays of HOPG and Heusler crystals to perform experiments with an unpolarized and a polarized neutron beam, respectively. Both monochromators have a variable vertical focus so that the optimum vertical focusing can be chosen for different neutron energies. In order to change between these two types of focusing crystal arrays a vertical translating mechanism is used to position the relevant monochromator in (or out) of the neutron beam. The complete system incl. the monochromator mechanism, goniometer stages per monochromator, the vertical translation mechanism and including all cabling was design, fabricated, assembled and tested by SwissNeutronics.
