Neutron measurement is the primary tool in SPARC tokamak for fusion power (Pfus) monitoring, research on physics of burning plasmas, validation neutronics simulation workflows, and providing feedback machine protection. A demanding target uncertainty (10% Pfus) coverage a wide dynamic range (>8 orders magnitude going up to 5 × 1019 n/s), coupled with fast-track timeline design deployment, make development neutron diagnostics challenging. Four subsystems are under that exploit high...
A disruption mitigation system (DMS) is under design for ITER to inject sufficient material deeply into the plasma rapid thermal shutdown and collisional suppression of any resulting runaway electrons. Progress on development both a shattered pellet injector (SPI) that produces large solid cryogenic pellets provide reliable deep penetration fast opening high flow rate gas valve massive injection (MGI) presented. Cryogenic deuterium neon up 25 mm in size have been formed accelerated with...
1. A specific disease of cattle is described which occurs sporadically in the East Coast fever areas eastern equatorial Africa. Clinically, acute cases are characterised by peculiar nervous symptoms, absence and blindness. Death most within 2 to 21 days onset illness. Chronic encountered from time may survive up 6 months. 2. The widespread Uganda. It affects both sexes all breeds, commonest young stock between months years age. has, however, been observed older animals. 3. Pathologically,...
A new 14 MeV neutron spectrometer utilizing the magnetic proton recoil (MPR) technique is under development for SPARC tokamak. This instrument measures neutrons by converting them into protons, whose momenta are subsequently analyzed using a series of magnets before detection an array scintillators known as hodoscope. In this work, we explore various solutions hodoscope detectors through laboratory tests with radioactive sources and simulations. We present findings on light collection pulse...
A 100-TeV-scale Hadron Collider (HC) with a nominal operation field of at least 15 T is being considered for the post-LHC era, which requires using Nb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Sn technology. Practical demonstration this level in an accelerator-quality magnet and substantial reduction costs are important requirements realization such machine. Fermilab has started development dipole demonstrator HC. The design based...
Fermilab in the framework of U.S. Magnet Development Program (MDP) has developed a Nb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Sn dipole demonstrator for post-LHC hadron collider. The magnet uses 60-mm aperture 4-layer shell-type graded coils. cable two innermost layers 28 strands 1.0 mm diameter and outermost 40 0.7 diameter.

A magnetic proton recoil (MPR) neutron spectrometer is being designed for SPARC, a high field (BT = 12 T), compact (R0 1.85 m, 0.57 m) tokamak currently under construction in Devens, MA, USA. MPR spectrometers are versatile tools making fidelity ab initio calibrated measurements of fusion flux spectra and have been used to infer power, ion temperature, fuel ratio, suprathermal populations at several performance experiments. The an large part determined by the design field, which disperses...
The SPARC tokamak is a high-field, Bt0 ∼12 T, medium-sized, R0 = 1.85 m, that presently under construction in Devens, MA, led by Commonwealth Fusion Systems. It will be used to de-risk the high-field path fusion power plant and demonstrate commercial viability of energy. SPARC’s first campaign plan achieve Qfus &gt; 1 using an ICRF-heated, &lt;10 MW, high current, Ip ∼ 8.5 L-mode fueled D–T gas injection, its second investigate H-mode operations D–D. To facilitate plasma control...
The disease known as Turning Sickness was first recorded by Mettam (1934) in this journal and later more fully described & Carmichael (1936). condition has been defined a protozoan encephalitis of cattle one the most striking features is demonstration schizonts indistinguishable from those East Coast fever cerebral lesions affected animals.

The U.S. Spallation Neutron Source (SNS) is an accelerator-based, pulsed neutron-scattering facility, currently in the process of ramping up neutron production. In order to ensure that SNS will meet its operational commitments as well provide for future facility upgrades with high reliability, we are developing a rf-driven, H(-) ion source based on water-cooled, ceramic aluminum nitride (AlN) plasma chamber. To date, early versions this have delivered 42 mA front end and unanalyzed beam...

The earliest known cases of the coincident disappearance tsetse-fly from an area affected with rinderpest occurred in Transvaal and Rhodesia early nineties last century (Stevenson Hamilton, 1911 1912). There is no doubt that fly either decreased or entirely disappeared various districts these two territories following great epizootic wild fauna. A satisfactory explanation has not yet been given to account for this remarkable phenomenon. Fuller (1923) a most interesting historical review...
The U.S. Spallation Neutron Source (SNS) is the leading accelerator‐based, pulsed neutron‐scattering facility, currently in process of ramping up neutron production. In order to insure meeting operational requirements as well providing for future facility beam power upgrades, a multifaceted H‐ ion source development program ongoing.
