The 750-keV H + Cockcroft-Walton at LANSCE will be replaced with a 4-rod RFQ with injection energy of 35 keV. The existing duoplasmatron source extraction optics need to be modified to produce up to 35 mA of H + current with an emittance <0.02 pi-cm-mrad (rms,norm) for injection into the RFQ. In addition to source modifications we need a new LEBT for transport and matching into the RFQ. The LEB...
Wire electro-discharge machining (WEDM) is a fully extended and competitive machining process widely used for hard and difficult to machine materials. In the present research, experimental investigation have been conducted to find out the wire wear rate at different machining parameter Such as peak current, pulse on time, pulse off time, based on full factorial design of experiment. Molybdenum ...
Previous studies on assert its suitability for use in proposed fusion reactors. may outperform in a fusion reactor environment based on its relatively flat critical-current profile in the 15 T–20 T range, resilience to applied strain, and reduced risk of induced radioactivity. A multifilament powder-intube conductor was designed, fabricated and tested with a focus on evaluating critical current...
Starting materials used were 99.8% pure nickel, 99.9% pure iron, 99.9% pure tantalum, and 99.9% pure molybdenum. The materials in a total weight of 500g were melted with a high-frequency induction furnace in vacuum. The melt was poured into an iron mold with an opening of 20mm diameter and 150mm length. After forging, the ingot was reduced to a thin plate 0.3mm in thickness by rolling and a wir...
