Main Application
Backscattering from a collimated source or beam target; angular correlation measurements.
  • Literature +

  • Mounting Arrangements +


    Mount must be specified when ordering.

    A
     This is a "ring mount"; i.e., the silicon wafer is offered on its ring without output connectors. This infrequently used arrangement is available on special request.

    T
     Microdot on the side of the can; without adjustable screws. (Open back.)

    Dimensions are given in millimeters.

    Mount must be specified when ordering.

    Supplied in T Mount unless specified otherwise by appropriate letter prefix; 4-mm hole is standard, 6- or 8-mm hole or other areas and depths available on special order.

    **First three digits of Model No. indicate total system resolution FWHM for 241Am, 5.486-MeV alphas, using standard ORTEC electronics and 0.5-µs shaping time constants. Beta resolution approximated by pulse generator width FWHM.

    NOTE: Alpha Suite Compatible Detectors: ULTRA-AS and Low-Background R Series detectors in B-mount are guaranteed compatible with the Alpha Suite products (DUO, MEGA, ARIA, ENSEMBLE).  All other detectors require an approved special for compatibility and warranted specifications.
