Harryman D, Colgan C, Lovell J, Moscheni M, Naylor G, Rengle A, et al.
Rev Sci Instrum . 2024 Aug; 95(8). PMID: 39158393
Following successful campaigns on the compact high field spherical tokamak ST40, resistive gold foil bolometers have now been installed to measure the radiated power profile. Positioned on the midplane, two...

Lovell J, Reinke M, Field A, Lomanowski B
Rev Sci Instrum . 2023 Mar; 94(2):023509. PMID: 36859004
A suite of multi-channel resistive bolometers has been implemented to measure the total radiation from Mega Amp Spherical Tokamak Upgrade plasmas, with cameras covering the core plasma and lower divertor...

Lovell J, Reinke M, Sheikh U, Sweeney R, Puglia P, Carvalho P, et al.
Rev Sci Instrum . 2021 Mar; 92(2):023502. PMID: 33648156
This paper presents techniques for evaluating the radiated power in JET disruptions. Disrupting plasmas are shown to have non-axisymmetric radiation profiles, motivating the re-evaluation of the standard techniques for calculating...

Vincent C, McCarthy W, Golfinopoulos T, LaBombard B, Sharples R, Lovell J, et al.
Rev Sci Instrum . 2019 Sep; 90(8):083504. PMID: 31472602
High bandwidth, high spatial resolution measurements of electron temperature, density, and plasma potential are valuable for resolving turbulence in the boundary plasma of tokamaks. While conventional Langmuir probes can provide...

Gregory S, Barlow K, McLay K, Kaul R, Swarbreck D, Dunham A, et al.
Nature . 2006 May; 441(7091):315-21. PMID: 16710414
The reference sequence for each human chromosome provides the framework for understanding genome function, variation and evolution. Here we report the finished sequence and biological annotation of human chromosome 1....

Krings T, Finney J, Niggemann P, Reinacher P, Luck N, Drexler A, et al.
Neuroradiology . 2006 Apr; 48(6):394-401. PMID: 16622696
Introduction: Standard microguidewires used in interventional neuroradiology have a predefined shape of the tip that cannot be changed while the guidewire is in the vessel. We evaluated a novel magnetic...

Humphray S, Oliver K, HUNT A, Plumb R, Loveland J, Howe K, et al.
Nature . 2004 May; 429(6990):369-74. PMID: 15164053
Chromosome 9 is highly structurally polymorphic. It contains the largest autosomal block of heterochromatin, which is heteromorphic in 6-8% of humans, whereas pericentric inversions occur in more than 1% of...
