This week, we have started to glue the large array of perfect-silicon crystal wafers, which form the energy analysers for our new EMU backscattering spectrometer, to their spherical backing plates. This work will take approximately four months, and a total of 700 crystal wafers, covering approximately 9m2, will be mounted.
These crystal arrays are the key element in the spectrometer, which will have an energy-transfer resolution of 1 μeV or better.
