AB  - The organic compound mesitylene combines an easy handling and a high hydrogen density. These properties qualifies the substance to be used in cold moderator systems. The performance of a mesitylene based cold moderator system has been investigated during a beamtime at the COSY facility of Forschungszentrum Jülich, where a tantalum target irradiated by a 45 MeV pulsed proton beam has been used to produce neutrons in a (p,n)-reaction. The mesitylene moderator system, cooled by a coldfinger cryocooler to temperatures between 22K and 300K, moderated the neutrons to long wavelength up to 40 Å. These cold neutron spectra has been measured by a 3He detector system in time-of-flight mode. In this talk the experimental setup and results will be presented.
