Re: Current Events Discussion
Hi guys, another couple of questions... So beams are now running at higher intensity (2e11) but the loss rate is much greater than with beams at 1e10. Is this how the beam is expected to behave during physics runs or something the beam commissioning is meant to prevent? When the beam is properly squ...

Re: Current Events Discussion
thanks again. I began to read this a while ago but didn't make it to the end, that clears things up this time round though.oxodoes wrote:see here: http://lhcportal.com/Forum/viewtopic.php?f=4&t=219

Re: Current Events Discussion
Yes the beam was lost! But this happens rather often and you will get used to it very soon ;) . Tune refers to the number of transversal oscillations of the beam envelope during one turn in the machine. (The tune is vitaly important for the stability of the beam as there might be resonances.) Dump ...

Re: Current Events Discussion
Right now (1800 CH time) it says there was an unprogrammed dump during tune trim. Does this mean the beam was lost while tweaking some of the parameters, hitting the side of the beam tube? If so does the energy released damage the tube? And if there were higher intensity beams could this ever cause ...

hello
Morning, just wanted to say hi. Been an LHC groupie for a while, this seems like a good place to find out more about what's going on day to day.
Hope to find out some interesting stuff here.
Cheers,
Ali.
