What can neutron imaging do for textile research

A significant part of cultural heritage contains textile in some shape or form. Inspired by the recent NICAS colloquium and match day, we decided to investigate piece of textile from a left-over symposium bag with neutron tomography. The piece of cloth was folded over a few times, inspired by a discussion with Paulien Coopmans on possibilities to investigate 17th century wardrobe textile, non-invasively.

The piece of textile was folded and put in an aluminium container for tomography measurement.

As shown in the reconstruction, the threads and patterns of the textile can be observed clearly. This example could be a showcase for neutron imaging application in textile art samples.

Status update

Long time no see! Although the FISH proposal was unfortunately rejected last year, we are not giving up on developing a neutron imaging station at our research reactor in Delft.

Over the last year, we have built a temporary imaging station on an existing beam line L2 next to our neutron powder diffractometer Pearl in the reactor hall. This low budget imaging station will serve to make a showcase for applications of neutron imaging and offer a strong support for the new FISH proposal. These developments also provide us with valuable experiences in developing and operating an imaging station.

In fact, with the help of our colleagues of the Paul Scherrer Institute in Switzerland and their camera setup, this temporary instrument is performing so well that we now focus more on its exploitation in science and engineering. We are now in the outreach phase to explore all possible applications and at the same time we see that the next gain that can be achieved for us is to optimize the way in which we collect data at the instrument (real time adaptive tomography). Similarly, the actual reconstruction of collected data into 3D models is as well a focus point in the near future where we foresee considerable gain.

We would like to thank our colleagues in Paul Scherrer Institut (PSI) for lending us a Midi camera box for the last two and half months. We have performed many test measurements with this detector system. Some nice images and videos are going to be posted in the blog soon!
