Abstract
PURPOSE:To perform specific heat measurement which is hardly affected by radiation loss by measuring the energy density at a place where the distribution of the energy density in a pulse beam emitted by a high-brightness light source is locally flat. CONSTITUTION:A heater 10 varies the temperature of a sample 4 from room temperature to specific high temperature. The sample 4 is placed in a vacuum tank 8 together with a hemispherical mirror 5 and a projecting beam 1 is guided in the sample 4 through the window of the vacuum tank 8. When the energy density of the beam 1 is measured, the energy of a part of the beam 1 is extracted by a beam splitter 2 and an energy density measuring instrument 3 monitors only the part where the energy density distribution is flat through an opening. Further, when the energy distribution of the beam 1 is measured, stainless steel foil coated with paint, for example, is provided at the same place with the same 4, the beam 1 is made incident on it, and the spatial distribution of the temperature raise of the stainless steel foil is observed by a heat image device 9 from the reverse side. Thus, the specific heat measurement which is hardly affected by radiation loss is performed.
