First results of proton injection commissioning of the AGS booster synchrotron

Beam performance results for the injection phase of proton beam commissioning of the Alternating Gradient Synchrotron (AGS) booster synchrotron are presented. The beam from the 200 MeV LINAC is transported through a new beam line into the booster. This LINAC-to-booster (LTB) beam line includes a 126 degrees bend and brings the injected beam onto the Booster injection orbit through the backleg of a main-ring dipole magnet. Transfer of the beam from the LINAC to the booster, the spiralling beam, and closing of the orbit in the booster ring are discussed. Injection and transport through one sector of the ring were accomplished. >
