Summary

BOLOMETER FOR DETECTING PARTICLES WITH VERY LOW ENERGY. POSSIBLE APPLICATIONS: NEUTRINO MASS, DETECTION OF COSMIONS, ENERGY OF ELECTROMAGNETIC PHOTONS. DESCRIPTION AND ADVANTAGES OF THE COMPOSITE BOLOMETER IN WHICH HEAT ABSORPTION AND DIFFUSION AND THE CONVERSION OF TEMPERATURE INTO ELECTRIC IMPULSE ARE PROVIDED BY DIFFERENT MATERIALS. AT 0. 1 K IT WOULD BE THEORETICALLY POSSIBLE TO DETECT A 100 ELECTRONVOLTS PHOTON. TWO GROUPS OF RESEARCH WORKERS ARE WORKING ON THIS SUBJECT, ONE INCLUDING THE ASTROPHYSICAL DEPARTMENT AT SACLAY, CERN-ISOLDE, NEW YORK AND GOTEBORG UNIVERSITIES, THE OTHER THE WISCONSIN UNIVERSITY AND THE SPACE CENTRE AT GODDARD. THE RESULTS ARE SUCH THAT IT IS ENVISAGED TO INCLUDE THIS TYPE OF BOLOMETER IN 1990 SPACE ASTRONOMY PROJECTS. THIS TYPE OF DETECTOR IS QUASI-UNIVERSAL AND ALREADY CONTRIBUTESTO PLURIDISCIPLINARY RESEARCH. J. V.
