19 MAR, NEW RECORD BEAM ENERGY
Commissioning of the LHC continues at a very encouraging rate. In the past few days the protection systems have been qualified such that the beams could be safely accelerated to higher energies. In the early hours of this morning, around 5:30am Geneva time, both beams were successfully ramped to 3.5 TeV, 3 times higher than ever before! Even more encouraging, the beams were extremely stable during this period and had a very long lifetime.

The four detectors are hot and ready for First Physics at 3.5TeV per beam.

7 TeV collisions now taking place in all 4 experiments! A world record and a huge testament to the engineering and technological capabilities of human beings.
Unfortunately the world hasn't ended so I imagine the media won't be bothered much except perhaps to whine about the cost.

Cool
This is a superb project, a marvel of engineering, collaboration, and exploration from all corners of the world. The young should be encouraged and stimulated by projects like the LHC. Much like the Bloodhound project Richard Noble started, it helps to get children and adults inspired to work together and do great things.We need more of this sort of thing, it reminds us of what it means to be human.
Yes, I have no desire to see the world end. I was having a dig at the media who could choose to have a major positive influence by reporting things appropriately, however unfortunately they only seem to be interested when things may or do go wrong. Remember all that Doomsday "blackhole will eat the Earth" bollox that got so much air-time last year?

I like some of the pre-ramp checks, see point 7 during prep......

Pre-ramp
• Preparation for the ramp:
o don't incorporate from the sequencer just yet
o Generation application, incorporation tab
o select from beam process - RAMP_3.5TeV_2Aps_short_V1@0[START]
o select to beam process - RAMP_3.5TeV_2Aps_short_V1
o click button - show not incorporated parameters - wait 2-3 minutes
o this will show a list of systems where the program has found discontinuities
o don't panic
o choose ORBIT-H, this will show a list of type groups, choose K (only!), select all parameters shown and hit incorporate parameters
• Repeat for:
o ORBIT-V, at K level
o Tune at knob level
o Chromaticity at knob level.
o Coupling at knob level
• If you've only trimmed orbit, tune and chromaticity - the ramp should now load. Please be careful about incorporating other stuff especially if the beta beat team has been in action.
• Launch prepare ramp
etc
