Cold Source

The cold source of the BER-II reactor has been replaced with a new design which increases the flux by 60% at FLEXX in the wavelength range of interest. Additionally the guides have been completely replaced upgrading from a 58Ni coating to a supermirror coating.

The curved neutron guide for FLEXX uses supermirror coatings with m=3. To further maximize the neutron flux at FLEXX, the width of the guide has been doubled to 6cm.
