DEVELOPMENTS AND PLANS FOR DIAGNOSTICS ON THE ISIS SYNCHROTRON.

the UK, are described. Recent upgrades to instrumentation and control computers have made much more information readily available, which is valuable for control of a loss limited, high intensity machine. Measurements on high intensity beams have fundamental limitations in terms of accuracy, detail and interpretation. However, it is found that use of specially configured low intensity diagnostic beams can provide much detailed information not otherwise available, which is extremely valuable after careful interpretation. The methods and systems being developed to help trouble shooting, to find optimal conditions rapidly and systematically, and to improve understanding of high intensity performance are described. 1
