Fig. 2.

Two-body dangling model for HOLMES microcalorimeter pulses simulation. The TES is represented by the gray body, the absorber part of the microcalorimeter where the ${}^{163}$Ho is implanted is depicted in yellow and the dangling body is illustrated in light-blue. Whenever a ${}^{163}$Ho decay occurs in the absorber, a release of energy E, corresponding to a power P (depicted in red in the scheme), triggers the microcalorimeter response which depends both on the electric and thermal circuit parameters
