Best regards from the NDS2023 Team!
From the 10th to 12th July 2023, the ILL is organising the 6th International Workshop on Neutron Delivery Systems in Grenoble, France. For more details on dates and times please check our timetable.
We will share new insights concerning projects and installations from various neutron sources all over the world. A three-day event is proposed including talks with key leaders in the neutron community and a visit of the ILL experimental halls with their new guides and instruments.
The following topics will be addressed:
- Review of newly installed or planned neutron guide systems worldwide
- Progress in neutron guide design, innovative concepts and materials
- Flux measurement methods and guide system monitoring
- Advances in mirror and super-mirror science and technology (reflectivity, polarization, non-magnetic mirrors, ...)
- Simulation of neutron sources, compact sources and neutron transport
- Neutron optics (monochromators, polarisers, focusing, time of flight, ...)
- Shielding (Radioprotection, background, ...)
- Neutron guide lifespan and maintenance
- Moderation of neutrons for the production of cold and ultra-cold neutrons
In addition to the presentations, there will be a specialized exhibition of leading industrial suppliers from Neutron Delivery System engineering.
The call for abstracts is now open! Please submit your propositions here.
All chosen speakers are required to submit 1-3 pages which will be published in our event brochure.
At the ILL, we strive to create open discussion platforms that are accessible to all interested parties and especially to young engineers or scientists.

ILL 2023 program and long shutdown activities
In 2020, the ILL launched the multiannual ILL20-23 programme, which combines a major upgrade of the instrument suite (Endurance) with additional security and safety improvements for the reactor operations. ILL20-23 has been conducted based on a master resource-loaded programme schedule for coordinating instrumentation work and reactor activities during long shutdowns, whilst securing a maximum number of reactor cycles.
We will present the program organisation and way of operating as well as the work achieved during the most recent 2021-2022 long reactor shutdown period, a crucial part of the ILL20-23 programme. Dozens of ILL employees have indeed been involved in what has been a particularly intense period. The work has called for concerted efforts and goodwill of ILL staff within the Projects and Techniques (DPT), Reactor (DRe) and the Science Division (DS) and the Administration division.
As a result, the H1H2 long shutdown has been completed in line with its forecasted 16-month duration and on budget, leading to unpreceeding reliability and safety levels of its neutron reactor, the delivery of a fully modernised H24 guide, the primary part of the future H15 guides as well as a number of new world-class instruments now in operation.Speaker: Jerome Beaucour -

An Update on the Development of a Cold Neutron Source and Cold Neutron Beam Facilities at the Penn State Breazeale Reactor
A third generation, mesitylene moderated cold neutron source (CNS) was designed, built and is being installed at the Penn State Breazeale Reactor (PSBR) at the Radiation Science and Engineer- ing Center (RSEC). The main components of the PSU-CNS are a cold source cryocooler system and neutron guide system. Components of the cold source cryocooler system are a vacuum system, helium circulating and buffer system, compressor system, and mesitylene moderator. Mesitylene, a room temperature liquid, is frozen to solid form in a chamber to act as the cooling moderator. Circulating helium lines are attached to a cryocooler used to cool and maintain cold temperature of the mesitylene moderator using the method of forced flow helium gas circulated between the refrigeration unit (Cryocooler). A helium loop cools and maintains a cold neutron mesitylene mod- erating material at about 20 K in a 10 cm diameter aluminum chamber located inside the D2O tank of the PSBR. The mesitylene moderator chamber, circulating helium lines, and moderator lines are isolated in a vacuum system for isolation from thermal transfer. The cold neutrons coming from the mesitylene chamber are transported out of the biological shield of the reactor with three super- mirror neutron guides. The in-pile neutron guide system of the PSU-CNS contains 3 independently adjustable in-pile segments. The supermirror neutron guide cross-sections are GT1- 40 x 40 mm, GT2- 25 mm x 70 mm, GT3- 25 mm x 25 mm constructed of borated float glass each ~5 mm thick with a surface coating of m=3 QC on all sides. Each is a 0 m radius straight guide of 2.8m in length. Each in-pile guide is separated with material effective for shielding neutron and gamma radiation. The shielding and guide section with independent adjustment features has been designed to inte- grate into the in-pile vacuum housing, with optimal guide alignment with the moderator chamber. The three in-pile guides extend to out-of-pile guides with several different sections for Small Angle Neutron Scattering, Neutron Depth Profiling and Prompt Gamma Activation guide systems with straight guides, beam benders, and parabolic focusing guides with different surface coatings. The neutron guide elements were designed and are being built by Mirrotron Ltd. Budapest, Hungary.
The PSBR is a 1 MW, TRIGA with moveable core in a large pool and with pulsing capabilities. In steady-state operation at 1 MW, the thermal neutron flux is 1x1013 n/cm2sec at the edge of the core and 3x1013 n/cm2sec at the central thimble. The PSBR can also pulse with the peak flux for maximum pulse ~ 6x1016 n/cm2sec with pulse half width of ~10 msec. The RSEC facilities are heavily used for nuclear science and engineering research and education. A detailed description of the PSU-CNS will be presented.Speaker: Kenan Unlu (Penn State University) -

Efficient Neutron Transport and Imaging with Magnetic Lenses
Magnetic lenses have been developed for neutron beam transport. When the spin is parallel to the magnetic field, the neutron beam is focused by a sextupole magnet due to the magnetic dipole moment of the neutrons. On the other hand, the rest of the neutron beam is defocused. We are developing a powerful permanent magnet type sextupole lens which enables focal length modulation in synchronization with TOF. The status of the development research will be presented.
