Fission Track Laboratory

Staff:

Dr David Chew

Location

Museum Building, TCD

Instrument:

Carl Zeiss AxioImager Z1m microscope with an Autoscan stage system coupled to an IDS uEye high-resolution digital colour camera.

Samples

 Apatite fission track mounts (typically mounted in 1.5 to 2 cm diameter epoxy resin discs)

Additional information:

The system is equipped with the Autoscan Track Studio Suite Version 3 software.  It enables counting on screen and incorporates an image acquisition module that automatically acquires a series of reflected and transmitted light images at each area selected for counting. These can be archived and a separate automated counting and review module can also be used offline to analyse the data.
