Injection into LHC of bunches at 25 ns spacing

The objective of the MD was the injection into LHC of batches of nominal intensity bunches at 25 ns spacing, with setting up of the relevant machine systems and first observations of beam characteristics and identification of potential issues. During the test, the beams were setup in the SPS and bot...

description The objective of the MD was the injection into LHC of batches of nominal intensity bunches at 25 ns spacing, with setting up of the relevant machine systems and first observations of beam characteristics and identification of potential issues. During the test, the beams were setup in the SPS and both transfer lines, and trains of 24 bunches at 25 ns spacing were injected into LHC for both beams. A total of 216b per beam were accumulated (9 injections), limited only by the time available. In this note observations are presented on setting up of the lines, beam losses at injection, beam instrumentation performance, damper, RF capture, vacuum pressures, beam screen temperatures, bunch emittances and lifetimes. Some conclusions are drawn and suggestions for future MD discussed.
