Abstract
The Thermal Neutron Spectrum of Çekmece TR-1 was measured by using a double drystal spectrometer and NaCf crystal with its (200) plane as monochromator. The neutron energy which corresponds to the maximum of thermal flux distribution was found to be E(0) = 0,0595 ev.
Assuming that the flux distribution to be Maxwellian an attempt was made to analyze the measured data to evaluate the effective neutron temperature in the beam hole. Because the theoretical expressions given in the latest publications are found to be unsatisfactory in representing neutron reflectivity for slow neutrons, an experiment was carried out to determine the reflectivity in dependence of neutron
energy, the results of the experiment showed that the reflectivity in proportional to E-0,45. By using this empirical relation the effective neutron temperature was found to be ≈ 337°K.
