C-SPEC: Cold chopper spectrometer

LLB is engaged at various levels in the construction of five spectrometers around ESS (European Spallation Source in Sweden)

Among them, C-SPEC is the "Cold Chopper Spectrometer".

C-SPEC will be used in a wide variety of scientific applications, spanning the life sciences, functional materials and chemistry. Its key capability is to follow kinetic events in situ or in operando, enabled by very high flux.

C-SPEC is a direct geometry time of flight spectrometer developed as a German/French collaboration between FRM II and LLB. While both institutions are strong in soft matter and biophysics research, LLB additionally focuses on physical chemistry, magnetism, superconductivity, and structural and phase transition studies. FRM II specializes in materials science, structure research, quantum phenomena, nuclear and particle physics, and neutron methods. The result of this partnership is a workhorse spectrometer that will deliver results for both an academic and industrial user base.  Read more on the ESS Web site...
