Development at ISIS is a continuous process, driven in response to the changing needs of the user community and to maintain ISIS as a world-class neutron and muon source.

Sample Environment

In addition to development of instrument hardware, improved scientific capabilities are also enabled through creation of new sample environment equipment, including, this year:

  • A 1270 K furnace which allows the sample electrical resistance measurement for Polaris.
  • A variable temperature (110K-500K) insert for the Paris-Edinburgh pressure.
  • A variable path length, high pressure cell, obtained from Thar Inc (USA), for super-critical CO₂ experiments on LOQ.
  • PTFE-coated sample containers for corrosive liquids and a 10kbar pressure cell for SANDALS.

Detector development at ISIS is an ongoing requirement to enable new scientific capabilities from the instrument suite. New detector technologies have been needed to enable to full potential of TS-2 instruments to be realised, through improvements in spatial capabilities, for example.

Developments include revised detector electronics such as a new pre-amplifier for WISH to improve noise immunity and a new ADC card for LET and WISH which carries out the entire signal processing in firmware.
