Book excerpt: Slow feedback has been developed to control the energy and energy spread of the beams which are injected into the SLC damping rings. Within a single RF pulse, two bunches of electrons and one bunch of positrons are accelerated to an energy of 1.21 GeV in the injector of the SLC. The two electron bunches are deflected into the north damping ring while the positrons are targeted into the south ring. In order to fit into the acceptance of the rings, the composite energy deviation and energy spread of the beams must be less than 2% full width. Control of the beam energy characteristics is accomplished with a set of computer controlled feedback loops which monitor the parameters of the three bunches and make adjustments to the available RF energy, RF phasing, and RF timing. This paper presents an overview of the feedback algorithms and of the special hardware developments, and reports on the operational status of the processes.

Book excerpt: A simple model is constructed for the SLC positron system to describe the intensity variations induced by beam loading in the linac. It is found that the system can be described by the well known logistic equation. This allows us to use results from the stability analysis to characterize the positron system, to place tolerances on fluctuations. and to slow variations on the scavenger beam intensity.

Book excerpt: The energy of the SLC scavenger electron beam used to produce positrons for the next cycle and the average energy of the electron and positron bunches collided in the linear collider must be stable to maintain efficient machine operating conditions. Energies are stabilized using a newly installed hardware-based feed forward system. The three bunches are stored and cooled in the damping rings, and co-accelerated in a single machine cycle. Prior to extraction of the stored bunches, the energy gain of the accelerator is set by re-phasing of klystrons to correct for anticipated beam loading effects. We will discuss the hardware associated with determining the intensities and the appropriate energy corrections to compensate for variations in energy due to beam loading effects. We will discuss machine tuning procedures, diagnostics, and operational experience. 8 refs., 5 figs.
