Aaron Craft draws everyone's attention to a Technical Meeting on Advances in Neutron Detectors for Neutron Scattering and Imaging Applications hosted by the IAEA to be held virtually via Cisco Webex from 30 August to 3 September 2021.   
The purpose of the event is to review developments in neutron detectors for neutron scattering and neutron imaging applications, providing a platform for international cooperation and networking of future developments in these fields. A completed Participation Form was required before 7 June 2021.  

Prof. Wolfgang Treimer invited research paper submissions for a special "Advances in Neutron Imaging" issue of the journal Applied Sciences. 
The aim is to publish many different papers on neutron imaging to popularize this technique in neutron scattering and other interdisciplinary scientific research.
 
Prof. Fayçal KHARFI has announced that the 1st International Conference and School on Radiation Imaging (ICSRI), scheduled for 2020 at Ferhat Abbas University, Algeria has been relaunched for 26-30 Sept 2021 in Setif. Date for submission of abstracts is at :-

Figure 2. Image registration and phase segmentation.

(a) Sagittal slices of registered NT image, XRT image, and checkerboard comparison of both, for a representative specimen from the Treated group. The colour bar shows relative attenuation.

(b) Mean joint histogram, composed of all specimen-specific joint histograms, with six peaks (centres marked as black dots) corresponding to material phases found in all datasets. Specimen-specific joint histograms are available as supplementary material (figures 1 and 2 (available online at stacks.iop.org/PMB/66/135016/mmedia)).

(c) Histograms for NT (blue) and XRT (red), shown as the mean of each modality (bold line) with standard deviation (shaded area). Peaks or grey value regions corresponding to the investigated structures are indicated with arrows. Note that the dips in the shaded area for NT corresponds to where mean minus standard deviation reaches negative values in linear scale.

(d) Example of a phase diagram showing the distribution of grey values assigned to each phase based on fitted bivariate Gaussian functions. Grey value pairs not assigned to any phase are white.

(e) Phase segmentation of material phases based on the mapping of the phase diagram (d) to the image data (a).

Frikkie de Beer has announced his early

retirement from Necsa, Pretoria. In his

32 years at Necsa, he created and made

operational a microfocus X-ray CT facility

that complemented the NRAD facility on

the South African SAFARI-1 reactor that is currently in the process of being upgraded to maintain these facilities as one of the major laboratories in the field of nuclear NDT studies.  He has been involved in many international projects at laboratories around the world and been instrumental in furthering the use of neutron techniques in NDT with students and professional users in South African industry and academia. He has been president of the International Society of Neutron Radiography and hosted the highly successful World Conference on Neutron Radiography WCNR-9 at the Kwa-Maritane, Pilansberg National Park in 2010. We wish him good health and success in his new projects.

News from Argentina that due to the deteriorating COVID-19 situation, the 6th ITMNR meeting in Buenos Aires has been postponed.

After 40 years of successful neutron research in Berlin-Wannsee, the research reactor BER II was finally shut down at the end of 2019. It will be dismantled over the next two decades.
