surrounded by a liquid helium jacket. The initial cool-down time is of 2.5 hours. The coil produces a maximum horizontal pulsed-field of 40 Tesla with a rise time of 23 ms every 8-9 min using a 1.15 MJ tr ... the liquid-helium reservoir. It has a very low liquid-helium boil-off and requires less than a refill per week. The centre of the cryostat ...

neutron diffraction over a range of temperatures from 5 to 295 K. We show that a considerable improvement occurs by representing the internal modes by a single second-rank tensor and that a further improvement ... improvement follows by including a Grüneisen parameter to account for volume thermal expansion. By applying the treatment to ...

A four-chopper ... assembly generates pulses with a choice of optimum flux or resolution. Two deflector mirrors direct the neutrons upwards or downwards towards ...
