The ITER Neutral Beam Test Facility (NBTF), called PRIMA (Padova Research on Megavolt Accelerator), is hosted in Padova, Italy and includes two experiments: MITICA, the full-scale prototype of heating neutral beam injector, SPIDER, full-size radio frequency negative-ions source. NBTF realization exploitation SPIDER MITICA have been recognized as necessary to make future operation injectors efficient reliable, fundamental achievement thermonuclear-relevant plasma parameters ITER. This paper...
Abstract The negative-ion based neutral beam injector for heating and current drive of the ITER plasma (ITER HNB) is under development, at present focusing on optimization full-scale source in SPIDER test stand. production H − or D ions ion low work function surfaces obtained by caesium evaporation. This paper describes conditioning procedure corresponding performances during first operation with caesium. Technical solutions to overcome limitations stand are described. influence parameters...
Heating neutral beam (HNB) injectors, necessary to achieve burning conditions and control plasma instabilities in ITER, are characterized by such demanding parameters that a test facility (NBTF) dedicated their development optimization is being realized Padua (Italy) with direct contributions from the Italian government (through Consorzio RFX as host entity) ITER international organization (with kind domestic agencies of Europe, Japan India) technical scientific support various European...
The requirements of ITER neutral beam injectors (1 MeV, 40 A negative deuterium ion current for 1 h) have never been simultaneously attained; therefore, a dedicated Neutral Beam Test Facility (NBTF) was set up at Consorzio RFX (Padova, Italy). NBTF includes two experiments: SPIDER (Source the Production Ions Deuterium Extracted from Rf plasma), full-scale prototype source injectors, with 100 keV accelerator, to investigate and optimize properties source; MITICA, entire injector, devoted...
SPIDER is one of the two projects ITER Neutral Beam Test Facility (NBTF) under construction in Padova, Italy, at Consorzio RFX premises; it will have a 100 keV beam source with full-size prototype radiofrequency (RF) ion for Injector (NBI), designed to operate pulse length up 3600 s, featuring ITER-like filter field configuration, caesium oven layout and wide set diagnostics.These features allow reproducing operation like as cannot be done any other existing test facility.SPIDER realization...
An overview of the recent operations and main results cesium injection in Source for Production Ions Deuterium Extracted from Rf plasma (SPIDER) negative ion source are described this contribution. In experiments without injection, all SPIDER plants were tested to verify basic expectations on operational parameters (e.g., electron cooling effectiveness magnetic filter field) determine its region. For beam properties, it was shown that current density varies across vertical direction....
In addition to its special physicochemical characteristics, such as their large surface area, biocompatibility, simplicity of functionalization, and capacity enable regulated drug release, gold nanoparticles (AuNPs) have drawn a lot interest in the field delivery. Because these AuNPs are excellent choices for targeted administration, improving stability, bioavailability, therapeutic effectiveness range medications. Functional groups like antibodies well peptides from or small molecules can...
Triazine, one of the nitrogen containing heterocyclic compounds has attracted considerable interest researchers due to vast array biological properties such as anti-viral, antitumor, anti-convulsant, analgesic, antioxidant, anti-depressant, herbicidal, insecticidal, fungicidal, antibacterial and anti-inflammatory activities offered by it. Various agents have been synthesized curb bacterial diseases but rapid development in drug resistance, tolerance side effects, there had always a need for...
Waste management has now become a necessary practice in all countries around the world. India generates approximately 65 million tons of garbage every year. The main challenge is to manage this waste. Conventional systems are not efficient much amount IoT can play dominant role handling waste and making any country greener more efficient. Time disposal important if ignored be health hazard. current system for local areas small densely populated cities inactive which causes spread over area....
Abstract A novel series of 11 C‐3– and N‐1–substituted oxoacetamide indole derivatives were synthesized by reacting with various aromatic amines alkyl halides. These compounds characterized using spectral techniques, ie , 1 HNMR, HNMR‐D 2 O, 13 CNMR, UV, elemental analysis, IR, mass spectrometery. In vitro antimicrobial studies resultant carried out against two bacterial strains, Pseudomonas aeruginosa oryzihabitans disc plate method. All the tested showed vital efficiency as agents both...
Neutral beam injection (NBI) for plasma heating and current drive is necessary International Thermonuclear Experimental reactor (ITER) tokamak. Due to its various advantages, a radio frequency (RF) driven source type was selected as reference ion the ITER NBI. The relevant RF negative sources are inductively coupled (IC) devices whose operational working has been chosen be 1 MHz characterized by high power density (∼9.4 W cm−3) low pressure (around 0.3 Pa). field produced coil in cylindrical...
