Over the last 10 years the cost of helium has increased by over 300%. ISIS is a major user of helium,
as liquid to cryogenically cool samples on the instruments and as gas in the target stations. Two thirds of
ISIS experiments use liquid helium, and this looks set to increase.
The recovery facility has supplied Target Station 1 and the instruments and labs on Target Station 2 with
recycled Helium for the last 2 operational cycles - a yearly saving for the target group alone is over £35K.
Soon recycled helium for Target Station 2 and the instruments and labs on target station 1 will be available
as well, which could save a further £100k / year. With the addition and commissioning of a Helium liquefier
for the facility, the system is expected over the coming years to effect savings as high as £300k/year.
