CASIM is stretching technology and would be state-of-the-art worldwide.
Daresbury had a very bad shock when Diamond was located down south and we know very well that CASIM is crucial to the survival of the laboratory so you can understand people being nervous.
4GLS, which forms part of CASIM, involves experts from Liverpool, Manchester and Warrington, on a particle accelerator which generates extremely bright lights, ranging from infrared to extreme ultraviolet, to look at materials.
Labour MP Helen Southworth, whose Warrington South constituency is home to the lab, said it was vital the CASIM project comes to Daresbury.
The approval has been welcomed by Liverpool MP Louise Ellman who has been asking tough questions of ministers about CASIM.
We are determined that CASIM will come to Daresbury.
But answering a Parliamentary Question from Liverpool Riverside MP Louise Ellman, his successor Patricia Hewitt did not confirm Daresbury as the location for CASIM
But scientists have warned there was still a battle be won for the lab's future as the scientific argument for CASIM - Centre for Accelerator Science, Imaging and Medicine - still had to be made and cash then approved by the Treasury.
Any backtracking on the CASIM project would have disastrous repercussions for the North West.
