B Series Totally Depleted Silicon Surface Barrier Radiation Detector

Main Application
Particle identification, telescopes of detectors, any type of ΔE measurements. In addition to ΔE/Δx experiments, the uniformly high field of B Series detectors makes them the best choice for rise-time discrimination or for precision timing experiments. These detectors are also useful in any experiment where an A Series detectors is used; B Series detectors are preferable if radiation damage is likely.

  • 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.

    § Built into a Microdot connector only.

    For detectors 1500 or 2000 μm deep, add 1.5 mm to the Y dimension.

  • Ordering Information +


    Mount must be specified when ordering.

    Supplied with T Mount unless otherwise specified.

    * All standard totally depleted detectors are cut off-axis from the parent crystal at a specific angle that will minimize ion channeling. Supplied in T Mount unless specified otherwise by appropriate letter prefix. 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 pulser width FWHM.

    § Requires special order.

    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.
