  the frequency of photons?

        

        Possible participants: Gregory Goltsman, Alexey Semenov, 
 Dragos   Anghel, and Leonid Kuzmin.

         Possible scenario: Gregory represents existing concept,
    others discuss possible development

         Alexey - low temperature counter with SQUID

         Dragos - NHEB

         Leonid - SHEB

         we can compare  different concepts step by
step:

         absorption, quasiparticles, "quantum effeciency" 
(in   the  sense of number of quasiparticles)

         hot spot - hot quasiparticles, 

        voltage amplification - SIN current measurements - Quasiparticle
    amplifier
