Performance assessment of the antenna setup for the ITER plasma position reflectometry in-vessel systems.

The design of the in-vessel antennas for the ITER plasma position reflectometry diagnostic is very challenging due to the need to cope both with the space restrictions inside the vacuum vessel and with the high mechanical and thermal loads during ITER operation. Here, we present the work carried out to assess and optimise the design of the antenna. We show that the blanket modules surrounding the antenna strongly modify its characteristics and need to be considered from the early phases of the design.

Thermal analysis of the in-vessel components of the ITER plasma-position reflectometry.

The ITER plasma position reflectometry system measures the edge electron density profile of the plasma, providing real-time supplementary contribution to the magnetic measurements of the plasma-wall distance. Some of the system components will be in direct sight of the plasma and therefore subject to plasma and stray radiation, which may cause excessive temperatures and stresses. In this work, thermal finite element analysis of the antenna and adjacent waveguides is conducted with ANSYS V17 (ANSYS® Academic Research, Release 17.

Assessment of the measurement performance of the in-vessel system of gap 6 of the ITER plasma position reflectometer using a finite-difference time-domain Maxwell full-wave code.

We conducted a first assessment of the measurement performance of the in-vessel components at gap 6 of the ITER plasma position reflectometry with the aid of a synthetic Ordinary Mode (O-mode) broadband frequency-modulated continuous-wave reflectometer implemented with REFMUL, a 2D finite-difference time-domain full-wave Maxwell code. These simulations take into account the system location within the vacuum vessel as well as its access to the plasma. The plasma case considered is a baseline scenario from Fusion for Energy.

[The clinical and psychosocial profile of inmates in psychiatric hospitals in the State of Ceará, Brazil].

One of the most vexing problems in the context of psychiatric reform are the inmates of psychiatric hospitals institutionalized for one year or more. The long periods of hospitalization indicate that these inmates have been abandoned, which can aggravate their psychiatric disorders. This article seeks to trace a socio-demographic and clinical profile of the inmates of psychiatric hospitals in the State of Ceará, Brazil.

[Extracorporeal shockwave lithotripsy in children].

Upper urinary tract lithiasis is a rare condition in children in comparison to its incidence in the adult population. The distribution of lithiasis in children has been reported to be 56% for idiopathic lithiasis, 20% for metabolic lithiasis, and 25% for lithiasis associated with uropathy. Extracorporeal shock wave lithotripsy (ESWL) has become the treatment of choice for upper urinary tract calculi in the adult patient as well as in children after minor changes and complementary material had permitted the utilization of the Dornier HM-3 lithotripter in these small patients.
