LiMeS-lab: An integrated laboratory for the development of Liquid-Metal Shield technologies for fusion reactors
<p>The liquid metal shield laboratory (LiMeS-Lab) will provide the infrastructure to develop, test, and compare liquid metal divertor designs for future fusion reactors. The main research topics of LiMeS-lab will be liquid metal interactions with the substrate material of the divertor, the continuous circulation and capillary refilling of the liquid metal during intense plasma heat loading and the retention of plasma particles in the liquid metal. To facilitate the research, four new devices are in development at the Dutch Institute for Fundamental Energy Research and the Eindhoven University of Technology: LiMeS-AM: a custom metal 3D printer based on powder bed fusion; LiMeS-Wetting, a plasma device to study the wetting of liquid metals on various substrates with different surface treatments; LiMeS-PSI, a linear plasma generator specifically adapted to operate continuous liquid metal loops. Special diagnostic protection will also be implemented to perform measurements in long duration shots without being affected by the liquid metal vapor; LiMeS-TDS, a thermal desorption spectroscopy system to characterize deuterium retention in a metal vapor environment. Each of these devices has specific challenges due to the presence and deposition of metal vapors that need to be addressed in order to function. In this paper, an overview of LiMeS-Lab will be given and the conceptual designs of the last three devices will be presented.</p>
Data for paper "Designing a Boron Nitride Polyethylene Composite for Shielding Neutrons"
<p>Data set for the paper "Designing a Boron Nitride Polyethylene Composite for Shielding Neutrons" published in Applied Physics Letters Materials (<a href="http://doi.org/10.1063/5.0163377">https://doi.org/10.1063/5.0163377</a>). In this paper, we explore the three different ways to distribute boron-10 within HDPE. These three configurations are called: (1) blended, (2) ideal layered, and (3) manufacturable. Refer to the manuscript for details of these configurations.</p> <p>For the <strong>blended configuration</strong>, we have uploaded the feather files, which contain all the information that was tracked in Geant4. We have processed the ROOT files, outputted directly from Geant4, into feather files, which include the energy of each particle at the entry and exit surface of the shielding composite along with the particle type and interaction type. The feather files can be easily read into Python using pandas:</p> <pre><code>pd.read_feather(filename)</code></pre> <p>The feather files are labeled as "blended_B10enrich_seed1_processed_*.ftr". Each feather file contains information from ~10 ROOT files. The key information from these feather files, such as the number of neutrons and gammas exiting the shielding composite and effective dose ratio, is saved in a pickle file, called "blended_B10enrich_binned_seed1_compressed.pickle". The pickle files can be read into Python using:</p> <pre><code>with open(filename, 'rb') as pickle_file: dictionary = pickle.load(pickle_file)</code></pre> <p>For the <strong>ideal layered configuration</strong>, there are ~100 feather files that are available upon request. The corresponding pickle files for the ideal layered configuration are uploaded, see "layered_B10enrich_binned_compressed.pickle", which can be read into Python using the code provided above. </p> <p>For the <strong>manufacturable configuration</strong>, there are ~236 feather files that are ~2 GB each. To reduce the number of files uploaded to this repository, we have only uploaded the pickle files for this configuration (see "manufacturable_B10enrich_binned_compressed_*.pickle").</p> <p>Please contact the authors if you have additional questions (Advik Vira, avira@gatech.edu, or Phillip First, first@gatech.edu).</p>

Kite Shield / Каплевидный Щит
A drop-shaped or almond-shaped shield is a type of shield used in Europe in the 10th-14th centuries. Named for its corresponding shape, in the frontal projection it looked like an inverted drop or almond, with the sharp side pointing down. Каплевидный или миндалевидный щит — тип щита, применявшегося в Европе в X—XIV веках. Назван так за соответствующую форму, во фронтальной проекции напоминал перевёрнутую каплю или миндаль, острой стороной был направлен вниз. Source: Objaverse 1.0 / Sketchfab
14th Century Shield
Recreation of shield from 1335-1375. Made of wood, leather, gesso, and iron. By the mid-14th century, shields had become considerably smaller than the large "teardrop-kite" shields of the previous centuries. With the development of plate armor and its protection over the entire body, shields such as this began to fall out of use in warfare, but were still used in tournament settings.

Captain America Shield
Captain America's shield is a fictional item appearing in American comic books published by Marvel Comics. It is the primary defensive and offensive piece of equipment used by the Marvel Comics superhero Captain America; he is seldom seen without it. Over the years, Captain America has had the use of several different shields of varying composition and design. His original heater shield first appeared in Captain America Comics #1 (March 1941), published by Marvel's 1940s predecessor, Timely Comics. The circular shield best associated with the character debuted in the next issue, Captain America Comics #2. Captain America was created by the team of writer-artist Joe Simon and artist Jack Kirby.

Nackhälleskölden - Laser-scanned Bronze Shield
This is a 3D-scanned bronze shield that we borrowed from Länsmuseet Halland. This is a very unique item that we have been blessed to handle and 3D-scan. This shield (Nackhälleskölden) was found 1865 in a bog in Halland/Sweden. - http://mis.historiska.se/mis/sok/exhib.asp?id=43875 - https://sv.wikipedia.org/wiki/Fr%C3%B6slundask%C3%B6ldarna In order to scan this shield we used Handyscan 3D-scanner VIUscan. To process the shield and decimate the model we used Geomagic Studio. Feel free to download the file! By http://CreativeTools.se Source: Objaverse 1.0 / Sketchfab

The Parade Shield of King Erik XIV of Sweden
The [shield](https://goo.gl/mur2Uz) is part of a [suit of armour](https://goo.gl/HiWXTM) that was delivered to the [King](https://goo.gl/9fGJux) in 1562. The whole set was problably made in [Arboga](https://goo.gl/SgXxA1) and then sent to [Antwerp](https://goo.gl/nQdMm8) where it was decorated by the goldsmith Eliseus Libaerts, following drawings by the French artist [Etienne Delaune](https://goo.gl/QqLbuv). To create the relief decor the steel has been [chased](https://goo.gl/FzoAbd), [embossed](https://goo.gl/i8gDzz), [etched](https://goo.gl/mKJri6) and [gilded](https://goo.gl/XSUdps). The motif is inspired by tales from antiquity and depicts [amazons](https://goo.gl/nqvY1j) fighting male warriors. It is probably a battle scene from the [Trojan war](https://goo.gl/LXsTkq). According to the myth the amazons supported [King Priam of Troy](https://goo.gl/QBjvTe) in the war but also lost their queen [Penthesileia](https://goo.gl/YvCSFg) when she was killed by [Achilles](https://goo.gl/TVPqit).
