DO NOT APPLY DIRECTLY TO THE BUYER - PLEASE FOLLOW THE INSTRUCTIONS PROVIDED IN THE ADDITIONAL TEXT SECTION . - - - - - This requirement is for a pulsed power supply for the ISIS injection dipole. The new power supply will give a 15 kA pulsed output with a rise and fall time of 100 µs and a nominal flat top of 500 µs. The designated load is described in AW18-2. The supplier will specify the output cable to be used. The cable is expected to be a significant proportion of the load. The flat top, fall time and zero current stability of the pulsed output are critical to operational needs. A ‘Start Trigger’ will signal the beginning of the rise time. This will occur before the proton beam is present and is therefore of lower importance. The pulsed output is expected to be at operating current and stable by the time the beam is injected. A ‘Stop Tigger’ will then signal the beginning of the fall time. During this time the proton beam will be circulating in the synchrotron and passing through the magnets. The magnet current will fall to zero within 100 µs before acceleration of the protons begins. The current must then be stable at zero, when measured with no beam, for the remainder of the cycle. The power supply will be used at an operational facility and must have high performance, reliability and availability. It will be based on proven technology that is established in service. STFC staff will be trained by the supplier in the operation, maintenance, fault finding and repair of the power supply. The supplier will advise on a complete set of suitable spares, which will be quoted for as a separate item. STFC will consider purchase of the spares after successful testing of the power supply and cable. The requirement is for one power supply to provide current to the four injection dipole magnets in series, plus a complete set of spare parts. - - - - - Please see our e-sourcing portal for full details.
