(Burkhard Schillinger, for ISNR)
I was a master student at the old FRM reactor in Garching, north of Munich, in 1992 when I first met Arif.
He was doing quantum mechanics with Roland Gähler, which would later lead to his neutron interferometer. I had just built my own camera for one of the first neutron imaging detectors. Arif was enthusiastic, and he invited me to travel to NIST and to Los Alamos with him – which was a big thing for me as a student. Much later I learnt that he had even wanted to invite me to NIST for a couple of weeks, all paid, which my former boss did not permit.
But we developed a friendship that would flourish for the rest of his life. Arif was always enthusiastic, ready to support and endorse young scientists. In no time, NIST took over electronic neutron imaging, and after a little collaboration in the beginning, NIST developed one of the most successful neutron imaging facilities worldwide.
Arif was proud of his work, especially on his neutron interferometer that he built with his own hands, but he was also a proud father of a beloved daughter.
I met Arif again and again at many conferences and meetings world-wide. He supported the decision to build the FRM II reactor as external international expert, and he was also an advisor for the ODIN imaging project at the European spallation source. But he was also guest at my home, not the least at the famous wine tasting where we drank more bottles than we had participants.
Arif loved Bavaria, and he was most happy when he was holding a Weissbier in hand in many a beer garden or on mountain tops, with the prospect of more to come.
My wife Vladimira and I shared a sincere and heartfelt friendship with him. We met him last in Vienna, and when we go next time, there will be a big, Arif-shaped hole at the table, and we will miss him dearly.
Pater Dr. Otto Schärpf, a Jesuit priest and physicist working long time at ILL and TUM, was once challenged how he could unite his faith and physics. He replied “I do not want to imagine a heaven without physics.”
Arif, my friend, by now you know.
Thanks for your love and friendship.
The 11th World Conference on Neutron Radiography (September 2nd – 7th 2018)
ANSTO, the Australian organization for nuclear science and technology hosted that meeting of the experts in modern neutron imaging this year in “early spring” with temperatures between 15 and 20 °C. Although the destination was quite far from most places of the world, more than 120 participants made the trip to “down under”.
The request for oral presentations was so high, that for the first time parallel sessions were held on one day of the meeting. Almost all contributions were given in high technical and content quality. The best evidence was the high participation in all sessions, including the two poster session in later afternoon.
It was a clever decision made by the main organizer Ulf Garbe to use the lecture hall of the “Australian National Maritime Museum” for the conference, situated just in the bay of the Darling Harbor. Located in the middle of the vivid city of Sydney but accessible from all hotels on foot, a good technical infrastructure was provided.
NIST hosts NEUWAVE-9
Neutron imaging methods that exploit wavelength dependent phenomena for novel image contrasts have been well-developed through the series of workshops on NEUtron WAVElength dependent imaging (NEUWAVE). The U.S. National Institute of Standards and Technology (NIST) hosted NEUWAVE-9 from 11-14 JUN 2017, featuring a networking event on Sunday 11 JUN, oral sessions with 35 talks from 12-14 JUN, an evening poster session on 12 JUN with 19 posters, and a tour of the research facilities at the NIST Center for Neutron Research (NCNR). The 55 NEUWAVE participants represented more than 10 countries, and discussed the latest advancements in and applications of neutron Bragg-edge imaging, phase and dark field imaging, imaging detector technology, other energy-resolved imaging methods and neutron imaging facility developments.

v4.0 is released.
Open source CT reconstruction
MuhRec is an open source CT reconstruction software developed at Paul Scherrer Institut. It has a graphical user interface that guides the user through the tuning of the reconstruction. Several preprocessing algorithms are provided for artefact removal and correction of biases introduced by beam hardening and scattering.
We can now proudly announce that the 2018-I release of MuhRec (v4.0) is available for download at GitHub
