They do visits her on a fairly regular basis. These are free, though you may have to book several weeks in advance. Based near Oxford it is primarily a science research facility. A synchrotron that produces hard (and bright) X-rays, hence I am told the name: Diamond Light 🙂
You get a guided tour of the synchrotron itself buy a member of the staff. You also get to see some of the research that they are doing.
I found it absolutely fascinating, and it has a few small though really engaging interactive science stands I the large foyer. These are run by staff at the facility and were marvellous.
