Well Types: Open Face, Integral, End Well, Side Well, Through Well

If improved counting times are required, we recommend a well type detector. Careful selection of the well dimensions and crystal size thickness will optimize the performance for a specific application. There are several useful well type configurations, they include: End Well, Side Well, and Through Well. Some well designs achieve nearly 4π counting efficiency. The most popular applications for this type of detector are radioimmunoassay dose calibration and environmental sample testing. Call or send an email and we will help you make the proper selection. These units are available in all three basic styles: open face, integral or demountable. Consider these design issues when selecting a well type detector:

  • Gamma-ray energy
  • Activity of the sample
  • Crystal wall thickness surrounding the well
  • Physical well dimensions

We list here some of the well dimensions that we have fabricated in the past. Do not hesitate to contact us and ask us to provide a quote for sizes not shown here.
