ILL's commitment to the environment spans decades.
Since 1972, we delivered 2.660.193 litres of liquid He, recycled 87.8% of He and saved more than 14.3M€.
With more than 50 colleagues from European facilities, we are developing novel equipment to ensure innovative, successful and cost-efficient use of beam time at existing and future large scale facilities.
ILL is an institutional member of the International Society for Sample Environment with 14 facilities and 8 companies.
The horizontal field 17T cryomagnet funded by EPSRC and owned by T. Forgan, A. Holmes and E. Blackburn is available on D11, D22 and D33. It provides a +/-11° scattering angle through sapphire windows and allows the sample in the vacuum to be cooled down to 1.6K. The sample can also be used at atmospheric pressure and room temperature. This magnet is available to users in collaboration with the owners listed above.
In order to exploit the performance of the new instruments, to open new fields of science and to secure the availability of the existing equipment, we have proposed to establish new standards and develop or acquire missing equipment:
- Provide novel equipment and a much better support to investigate bio materials, liquids, surfaces and glasses,
- Enhance high-pressure and low temperature capabilities, Speed up the changes of the sample conditions to better exploit the instruments,
- Develop high-precision zero-field polarimetry to tackle the fundamentals of nature,
- Acquire high-field cryomagnets to exploit new world-class instruments.
The project has been welcomed by the Instrument Subcommittee and the Scientific Council. We now wait for a decision of the Associates…
The Agence National de la Recherche financed the design and construction of a 40T pulsed field magnet for neutron scattering (Magfins project).
Designed and built by the LNCMI-Toulouse, the coil produces a horizontal field up to 40 T with the 1.15 MJ transportable pulsed field power supply. The coil is installed inside a cryostat developed by the ILL.
The first experiments were carried out very successfully on IN22 down to 2 K and up to 40 T. Efforts are now being made to allow anyone to exploit this magnet…
We have upgraded the 120 mK dilution refrigerator mounted in the cradle of D10 with a 3He distiller and a new control rack. This very special dilution fridge is now operated very reliably in closed loop to preserve the 3He gas.
With Javier Campo (ICMA), we organised an advanced seminar with the aim to identify the scientific drivers requiring novel and extreme conditions, and determine how the neutron scattering techniques could contribute.
This workshop was held in Zaragoza (Spain) from the 27th to the 31st of May 2012.
A non-magnetic Eulerian cradle cooled down to 3.2K has successfully been commissioned on D3 in July 2013. You won't need to re-align your sample anymore when carrying out spherical polarimetry experiments!
We have developed a Goniostick for cryostats based on the idea of Berneron et al. (D7 in the early 80s). The prototype shown below has been tested successfully on IN5.
This non-magnetic goniometer fits inside Ø38 bore cryostats and provides ±7° sample tilt with 0.02° resolution (0.14° backlash managed by control software). It can be controlled manually with micrometer screws or remotely with motors.
We have proposed, within the frame of Endurance, to build a few copies for orienting crystals in cryostats and cryomagnets.
A 7T vertical field asymmetric magnet featuring a He recondensation unit has recently been commissioned. With single-crystalline sapphire windows at 90°, this cryomagnet fits perfectly with D17.
Since the upgrade of the ToF spectrometer IN5 with reliable position sensitive detectors, the demand for single crystal experiments combined with magnetic fields has increased dramatically as it allows an unprecedented exploration of the field effects on the dynamics through the entire reciprocal space.
To allow our neutron scattering community to tackle fundamental questions, we have decided to acquire a high-field magnet providing 90° horizontal access and ±15° vertical access. The commissioning of this magnet is planned in 2015.
The use of our equipment is scheduled in shared calendars. You can check your bookings and look for the availabilities before scheduling an experiment.
Please be careful in the vicinity of cryomagnets! The mechanical limits must always be installed and checked before starting an experiment.
Do you have a pioneering idea that could change the way we provide support to our users, or perhaps an innovation that could allow our users to carry out innovative experiments?
Either way, we value your opinion and welcome ideas on how we can improve. Leave us your feedback. Be assured that we will carefully review all suggestions.
