Out and about in Kyoto

A great time was had at ICPA20 in Takamatsu this week, here I am presenting my research on an impressively sized screen 🧪 #science #spectroscopy #positronium

Word of the Day is ‘apricate’ (17th century): to turn your face to the sun and bask in its warmth.

The @ALICEexperiment has seen the first ever evidence for antihyperhelium-4 — if confirmed, this will be the heaviest antimatter hypernucleus yet seen at the LHC

Word of the day is one I may have mentioned (frequently): a ‘snaccident’ is the inadvertent eating of an entire packet of biscuits.

3D printed coil bobbin + copper wire = small correction coil. The picture shows one being wound earlier in the week. We will use four of these to help guide our new positron beam into a two-stage buffer-gas trap #experimental #physics #3dprinting

Using Stellarium to learn more about the stars that zoom across the field of view for about 30 mins. Also wandering if I could capture some variability of a short time-scale variable star with this setup… hmm

Trying out some inside star gazing with my Askar FMA135 and ZWO ASI178MM, actually works surprisingly well with all the lights off 😄 #stargazing #astronomy #zwo #askar

Oh, its just an effect of the fish eye lens mode on iPhone

A post doc physicist kinda Friday evening 🧪 #physics #spectroscpy

Yes, how about you?

Yes, I took it earlier this evening in the UK. I have a passion for astronomy, but I am just a lowly atomic physicist in the day time 😄

Shot the California nebula tonight with the Samyang 135mm F2.0 stopped down to F4, only around an hour total due to getting too cold, but fairly decent result nevertheless #astrophotography #nebula

Word of the day is a favourite for this time of year. To be ‘crambazzled’, in old Yorkshire dialect, is to be prematurely aged by excess drinking or partying.

Merry Christmas!

Merry Xmas eve (in the UK) from the positronium spectroscopy lab 🧪 #physics #spectroscopy

When you remember to bring your camera. When you forget to bring your camera.

Precision spectroscopy of simple atomic systems can test one of our best theories of nature: QED. Studies with positronium are limited by broad velocity distributions. Research towards velocity-resolved spectroscopy is therefore very welcome: arxiv.org/pdf/2411.19872 #physics #research #spectroscopy

Hello, could I please be added to the list I’m an experimental atomic/antimatter physicist at UCL, thankyou! orcid.org/0000-0001-59...

First PRL, doing some cool shit with circularly polarised microwaves and positronium #physics #research #postdoc

Finished building my positron trap #physics #antimatter
