| TUM1I01 | Cooling Results from LEIR | electron, ion, injection, gun | 55 | |||||
|
The LEIR electron cooler has been successfully commissioned for the cooling and stacking of Pb54+ ions in LEIR during 2006. The emphasis of the three short commissioning runs was to produce the so-called “early” beam needed for the first LHC ion run. In addition some time was spent investigating the difficulties that one might encounter in producing the nominal LHC ion beam. Cooling studies were also made whenever the machine operational mode made it possible, and we report on the preliminary results of the different measurements (cooling-down time, lifetime etc.) performed on the LEIR cooler. Our investigations also included a study of the influence of variable electron density distributions on the cooling performance.

| THAP16 | New Equalizers for Antiproton Stochastic Cooling at Fermilab | antiproton, accumulation | 202 | |||||
|
To maximize performance of Antiproton source stochastic cooling we developed and built equalizers correcting both phase and amplitude of the system gain. Design requirements have been based on the beam measurements of the system gain. Paper presents principles of the design and details of engineering, manufacturing and tuning of the equalizers.
