Abstract
A stainless steel vacuum chamber has been designed for the observation of luminescence emission from liquid or solid samples in the temperature range 80-380K following irradiation by pulses of high energy electrons. The samples may be irradiated in the presence of any gas at pressures between 1 mu Torr and 760 Torr. At low pressures and temperatures radiative heating of the sample becomes important and leads to thermal gradient in the sample. This effect has been investigated and reduced by the use of a cooled 'heat shield'.
