NRC Chalk River - Call for Proposals


 

Canada's Neutron Beam Laboratory is operated on a continuous proposal basis.
Proposals for experiments may be submitted at any time. Experiments are
given beam time on the basis of scientific merit.

 

The laboratory is operated as a user facility by the National Research
Council Canada. Proposal forms and information on the review process can be
found at:  http://neutron.nrc.gc.ca/beamtime.html
<http://neutron.nrc.gc.ca/beamtime.html> 

 

The laboratory currently operates five thermal neutron spectrometers, with
source flux up to 6.0E14 n/cm2/s and source height up to 300 mm. 

 

C2, High Resolution Powder Diffractometer 

C5, Polarized Beam Triple-Axis Spectrometer/Reflectometer 

E3, Materials Science Diffractometer 

L3, Strain-Scanning Diffractometer 

N5, Triple-Axis Spectrometer 

 

Specifications for each instrument are available at:
http://neutron.nrc.gc.ca/specs.html <http://neutron.nrc.gc.ca/specs.html>  

 

Key features of the laboratory include:

 

A stress-scanner: typical minimum spatial resolution 1mm3, locating accuracy
better than 0.1 mm, strain precision 0.5E-4, 32-element multiwire 3He
detector for high throughput, and a selection of computer-controlled X, Y, Z
and orientational positioning systems, handling loads up to 500 kg. 

 

A powder diffractometer: 800-channel detector spanning 80 degrees of
scattering angle simultaneously for high throughput with continuously
variable wavelength and adjustable collimation before monochromator 0.2, 0.4
or 0.6 degrees. 

 

A tensile testing machine, screw-driven, 50 kN max load, read-out in strain
or stress, with heater attachment for up to 300°C. 

 

A polarized-neutron triple-axis spectrometer with a flipping ratio from 22:1
to 32:1, and a focusing Heusler-alloy monochromator and analyzer under
development. 

Reflectometry capability better than 6 orders of magnitude dynamic range,
constant footprint control, and Q range between 0.005 Å-1 and 0.2 Å-1. 

 

The N5 triple-axis neutron spectrometer with automatic selection of
main-beam filters (sapphire, cold beryllium) 

 

The M2 cryomagnet with 2 T horizontal field, access 345°, minimum
temperature 1.8 K
