Abstract: A plasma-facing component for a plasma chamber, comprising: a plasma-facing target surface; an inlet through which to receive a coolant fluid and an outlet through which to expel the coolant fluid; and a plurality of internal cooling channels. Each cooling channel is connected to the inlet by a plurality of feed channels and to the outlet by a plurality of return channels, the feed channels being configured to direct coolant fluid against a region of a wall of the cooling channel. Respective openings of the feed and return channels into the cooling channel are arranged in non-overlapping repeating units along a length of the cooling channel. Each unit comprises openings of at least one feed channel and at least one return channel.

Abstract: A method of repairing a divertor or first wall surface in a tokamak plasma vessel. The divertor or first wall surface comprises a refractory metal having a melting point of at least 2000°C. A pressure of less than 25 mbar is maintained within the plasma vessel following the end of operation of the plasma vessel. The refractory metal is deposited onto the divertor or first wall surface within the plasma vessel via a deposition process which is one of: additive manufacturing; physical vapour deposition; thermal spray; arc ion plating; diode laser cladding; and chemical vapour deposition.
