Rajdeep Mondal does experiments, May 2024

Rajdeep Mondal is conducting research leading to a Ph.D. qualification from Queen Mary University of London. Here, Dr Steve Ooi is helping to use the machine, very generously, over two whole days. The equipment is a dilatometer, more images of which are available.

We were measuring length changes using a linear variable differential transformer, rather than a laser because the samples were only 3 mm in diameter.
