The Large Hadron Collider has demonstrated multi-bunch injection for the first time by injecting 24 bunches, arriving in batches of 4 at a time from the SPS. In the previous runs up to 13 bunches were used in each beam, but they need to inject more bunches to reach higher intensities. They have a target to collide 24 bunches throughout the month of August.
After a technical stop last week the LHC had been slow to get restarted properly but this latest test puts them back on track. Now they have to repeat the injection for both beams at the same time and ramp them to high energies for collisions. They will be hoping to do that in the next few days ready for August.
Eventually the LHC will circulate 2808 bunches in each beam and to do that they will have to be able to inject 72 bunches at a time from the SPS.
