“…A 10 B neutron conversion layer of 70 nm thickness was deposited on top of the CB-KID by electronbeam evaporation in an ultra-high vacuum chamber. A thin 10 B layer was used for this study as we are still optimizing the process of depositing 10 B to obtain a uniform layer.…”

Samples were examined using a superconducting (Nb) neutron imaging system employing a delay-line technique which in previous studies was shown to have high spatial resolution. We found excellent correspondence between neutron transmission and scanning electron microscope (SEM) images of Gd islands with sizes between 15 and 130 μm which were thermally-sprayed onto a Si substrate. Neutron transmission images could be used to identify tiny voids in a thermally-sprayed continuous Gd2O3 film on a Si substrate which could not be seen in SEM images. We also found that neutron transmission images revealed pattern formations, mosaic features and co-existing dendritic phases in Wood's metal samples with constituent elements Bi, Pb, Sn and Cd.These results demonstrate the merits of the current-biased kinetic inductance detector (CB-KID) system for practical studies in materials science. Moreover, we found that operating the detector at a more optimal temperature (7.9 K) appreciably improved the effective detection efficiency when compared to previous studies conducted at 4 K. This is because the effective size of hot-spots in the superconducting meanderline planes increases with temperature, which makes particle detections more likely.

“…To meet the specification that the VSANS instrument have a low-q limit of 2 Â 10 À4 A ˚À1 , a 2D detector with 1-2 mm spatial resolution over an area of $20 Â 20 cm is required. In seeking a commercial source for such a detector, various technologies were considered, including 3 He gas detectors (Marmotti et al, 2002), scintillator-based detectors (Nakamura et al, 2009;Iwase et al, 2012), micro-channel plate detectors (Siegmund et al, 2007), semiconductor detectors (Fronk et al, 2015) and others (Klein & Schmidt, 2011;Buffet et al, 2005). Highpressure (0.6-1.0 MPa) 3 He gas detectors, both multiwire proportional counters and microstrip gas counters (Clergeau et al, 2001), have achieved 1-2 mm resolution in isolated cases.…”

A description and the performance of the very small angle neutron scattering diffractometer at the National Institute of Standards and Technology are presented. The measurement range of the instrument extends over three decades of momentum transfer q from 2 × 10−4 to 0.7 Å−1. The entire scattering angle range from 8 × 10−5 to π/6 rad (30°) can be measured simultaneously using three separate detector carriages on rails holding nine 2D detector arrays. Versatile choices of collimation options and neutron wavelength selection allow the q resolution and beam intensity to be optimized for the needs of the experiment. High q resolution is achieved using multiple converging-beam collimation with circular pinholes combined with refractive lenses and prisms. Relaxed vertical resolution with much higher beam intensity can be achieved with narrow slit collimation and a broad wavelength range chosen by truncating the moderator source distribution below 4 Å with a Be crystalline filter and above 8 Å with a supermirror deflector. Polarized beam measurements with full polarization analysis are also provided by a high-performance supermirror polarizer and spin flipper, capable of producing flipping ratios of over 100, along with a high-efficiency 3He polarization analyzer.
