HINP16C (Heavy-Ion Nuclear Physics, 16Channel) is a 16 channel integrated circuit (IC) for use in a series of experiments in low- and intermediate-energy nuclear physics. The IC is fabricated in the AMIS 0.5 mm, N-well, double-poly, triple-metal, high-resistance C5N process through MOSIS. The die is 6 mm x 6 mm.

need for hinp32c
Need for HINP32C
  • Need for high density signal processing in low and intermediate energy nuclear physics community is widespread
  • No commercial chip was found to do exactly what we wanted. Necessary for the “experimenter” to be in the “designer’s seat”
  • Timing, self-triggering, and on chip sparsification non-existent or inadequate
  • Gain ranges beyond 50 MeV not available

sample applications
Sample Applications
  • Spectroscopy of low lying particle unstable states by resonance decay correlation techniques
  • Inverse (d,p) scattering experiments designed to study shell structure and pairing in n-rich nuclei
  • Inverse (p,d) reactions examining the n single particle structure of secondary unstable beams
  • Particle-particle correlation experiments at intermediate energy designed to refine temperature determinations and to image source characteristics
  • Si arrays for detecting  particles and CZT and Ge arrays for detecting  ray’s.
