The upgrade is to include a new long solenoid coil (designated P1), a new tight-radius solenoid coil (designated Pc) and a pair of shaping coils (Px). Together these are referred to as the Airside Coils.
The long solenoid is a resistive coil made of half-hard, oxygen free, high conductivity copper. The conductor is a hollow rectangular section of 12mm x 18mm, with the internal channel measuring at 5mm x 8mm. The coil is approximately 3.08m long and consists of 4 layers, each wound as a two start helix (two-in-hand) for a total of 324 turns. The centre radius of the coil is approximately 195mm.
The Pc and Px coils are resistive coils made of annealed, oxygen free, high conductivity copper. Basic dimensions of the Pc coils are 142 turns, 2 layers, each wound as a two start helix (two-in-hand), 67mm centre radius 10mm x 10mm conductor section and 4mm diameter cooling channel. Basic dimensions of the Px coils are 44 turns, 2 layers, 240.5mm centre radius 11mm x 8mm conductor section and 3mm x 3.5mm cooling channel.
The turns are individually wrapped with glass tape and then impregnated under vacuum with resin which bonds the turns together and provides electrical insulation. Regions devoid of copper are packed with machined solid insulating filler pieces. It is proposed to use cyanate ester resin (CTD 403 mix) with a high temperature primer (CTD 450).
The objective of this contract is the manufacture of the coils. Copper conductor will be free issued to the supplier.
The scope of work for the production of the airside coils (but is not limited to):
Procurement of bulk material with traceable certification.
The production of the manufacturing drawings.
Manufacture of all jigs and fixtures.
Winding the coil and preparing for vacuum impregnation.
Vacuum impregnation.
Dimensional inspection of all components.
Qualification of processes such as cleaning, vacuum impregnation and brazing of conductors (if needed).
Packaging & Delivery.
The works are to be carried out in an acceptably safe and environmentally responsible manner and all personnel are to be suitably qualified and experienced for the nature of the contract.

The Authotrity will decide wheter or not to accept this technical case and whether or not to include the third Px coil within the scope of supply.
Description of these options: Tenderers are required to unclude for the provision of a minimum of two Px Coils and a further ‘technology demonstrator’ Px coil. Tenderers may provide a technical case to support not needing to provide the third Px Coil.
The Authotrity will decide wheter or not to accept this technical case and whether or not to include the third Px coil within the scope of supply.
