Interested in doing a PhD in space heritage? If so, this opportunity might be for you!

PhD programme If you have a passion for science and its role in today’s world, and like the idea of making your own contribution to this fascinating field, we invite you to apply for an MPhil or PhD with us.

It's a really exciting project, perhaps of interest to recent MSc students in history of science/technology/space, museum or conservation studies

Information on our AHRC PhD studentship on 'Rescue curation of space heritage' also found here:

We have a 4-year AHRC-funded PhD studentship on 'Rescue curation of space heritage' advertised!

Supervision by me, space scientist Lucie Green (@luciegreen.bsky.social), and curators of space and engineering at the Science Museum, Doug Millard and Ben Russell

The big white building that contains JET at Culham

Entrance to Culham. 1980s building

Goodbye JET!

Two blue shipping containers, stacked

Detail of container with ID number and a warning sign pinned on

I do like a repurposed shipping container.

These are in the JET Assembly Hall

Concrete sculpture. Picture a three layered vertical concrete slab with a ninety degree twist

Culham’s campus/new town feel is complete with a concrete sculpture

Geoffrey Clarke RA’s ‘Plasma stabile’ (1965)

Apparently never finished. Like fusion

Warning sign. Says ‘controlled area. Radiation high. Contamination low. Observe local rules. No eating, drinking, smoking or chewing of gum is permitted in this area’

Don’t eat gum in the JET torus hall!

(actually this is good universal advice)

Observe local rules!

(more good universal advice)

JET’s doors are huge, meters thick and made of concrete. Picture shows group wearing hard hats by the doors which are painted white and yellow and are very high and thick

JET is protected by what, I am told, are the second biggest & heaviest doors in the world

(what’s number one??)

Inside the replica of the JET torus called Octant 9 with a remote handled robot

You can’t go into the inside of JET’s torus (it’s radioactive from the tritium) and you can’t see it from outside because of the mass of pipes

But in the assembly hall there is a replica, with the paradoxical name of ‘Octant 9’, in which the remote handlers practice with the repair robots

Two big silvery curved pipes

nice pipes

Lit yellow circle with a red emerging stop button

Plaque reads ‘Pushbutton to switch off JET. Press only in case of extreme emergency’

JET had an emergency off switch!

Part of JET with a the access hatch visible

The radio waveguides that helped power JET, made in Germany

To create a pulse of extreme temperature to start fusion, 3 gigawatts of power was needed in fractions of a second, via accelerated hydrogen and radio frequency heating (like a giant microwave), released partly by enormous inertial flywheels (perhaps a 10th of the energy of the UK)

Reads: ‘This foundation stone was laid on 18 May 1979 by Dr Guido Brunner, member of the Commission of the European Communities’

Part of JET built by De Pretto-Escher Wyss, Italia

It was Europe manifested in the Oxfordshire countryside.

A symbol and evidence of a European vision of an fusion energy future

Inside the centre of JET is a hollow metal donut shape that contained the plasma

Started in the late 1970s and operating, first with hydrogen and then with deuterium and tritium.

Behind all those pipes and wires was the torus chamber where plasma temperatures reached 150 million degrees

The floor is tungsten and the walls are beryllium

JET (Joint European Torus). Pictures shows lots of pipes and industrial infrastructure in a huge hall, perhaps 30m high

Going into see JET are people from museums, historians etc with hard hats. Sign above door says ‘The Assembly Hall and Torus Hall. Home of JET’

Had an amazing day on a tour of the Joint European Torus (JET) nuclear fusion facility, beginning to be decommissioned at Culham

and, awkwardly, a weakening over time…

Very nice. It’s a UK orchid - several species it could be - painted as a still life from a real specimen

is even better

Yes. New motto

“remains indispensable”

The Origins of Agar First introduced into laboratories in 1881, agar remains indispensable as a culture medium.

Green leaves, small white divided petal flowers on dark brick wall

Heart shaped leaves and small white flowers

Whitlow-grass (Draba verna) from a railway bridge wall in Dalston, London, and Scurvy-grass (Cochlearia sp.) from harbour wall in Portscatho, Cornwall

I’d like to apologise for my university’s craven actions, failing to defend staff and throwing the rest of the UK university sector under the bus on this issue.

UCL had the resources others do not have to fight this properly in court.

Greenish umbel flowers of Alexander’s

Primrose flower - very pale yellow with bright yellow centre

Lesser Celandine flower - eight yellow petals

More damp flowers for #wildflowerhour, this time from Cornish hedges: Alexanders, Primrose, Lesser Celandine
