ILC Conventional Positron Source: Long Pulse Drive Option
- SLAC
A conventional positron source for the ILC using a very long macro-pulse for the electron drive beam is proposed. In comparison with an undulator based positron source, a conventional positron source decouples positron production from the main linac electron beam, leading to faster commissioning and improved positron system up-time. Of the 200 ms in between ILC pulse trains, 100 ms will be used to make positrons. While this will make the positron target design easier, it will require the electron drive, positron capture linacs and the adiabatic matching device to run at 50% duty cycle or more and a pre-damping ring with sufficient damping power to prepare the beam for injection into the damping ring in 100 ms.
