And, lo, in the space things were built.
Here’s the latest, shiniest, iteration of our VUV setup, flanged on to a newly revamped VMI machine (just visible in the background), and a very old (but trusty) McPherson monochrometer (the blue thing).

The endless possibilities of space (pt II)
Not the most scientifically exciting post, granted, but how can you think about the new before clearing out the old…? And, as a bonus, it’s ridiculously satisfying to take down old set-ups which haven’t been touched for some time.
In this space, the new VUV set-up will be created.
It will be beautiful.
And then there will be some physics.

Vacuum-ultraviolet to infrared supercontinuum in hydrogen-filled photonic crystal fiber
Optica, Vol. 2, Issue 4, pp. 292-300 (2015)
doi: 10.1364/OPTICA.2.000292
A nice demonstration of ultra-broadband supercontinuum generation, right down into the VUV range for the first time, based around a kagomé fibre.
VUV chambers, mk. II
New vacuum chambers for generation of light in the vacuum ultraviolet (VUV) range (<190 nm, e.g. 5th, 6th and 7th harmonics of an 800 nm field).
Milled from a single piece of aluminium, breadboard mount points, and ports for light, vacuum and motion control.
Modular, shiny, beautiful.
