Abstract
Single bunch currents in the SRS have now been increased to over 100 mA injected at 600 MeV, with user beams of 50-60 mA at 2 GeV routinely obtained. Such high currents in short (500 MHz) bunches have necessitated attention to ensuring adequate lifetimes, including deliberate control of bunch volume to reduce Touschek losses. At lower energies substantial bunch lengthening has been experienced which has been compared with standard theoretical models. The associated prediction of chamber impedance has been compared with results obtained from mode shift experiments. Other aspects of single bunch behaviour in the SRS are also mentioned
