I'd expect Beta* to be between 1.0 and 1.5m, but a value of 10m is shown on this page http://op-webtools.web.cern.ch/op-webto ... =LHCCONFIG
Can someone explain the difference?
What value of Beta* are they using?

Aha! it drops down to 1.5m when squeezing the beam.jmc2000 wrote:I'd expect Beta* to be between 1.0 and 1.5m, but a value of 10m is shown on this page http://op-webtools.web.cern.ch/op-webto ... =LHCCONFIG

But how on earth are they getting luminosities of 1.9/nb/s while keeping beta* and bunch intensity as they were two weeks ago? Emittance decrease was supposed to give 1.5/nb/s max!!
Re: What value of Beta* are they using?
For the final run they're using a value of beta* = 1.0m which should increase the luminosity by a factor of 1.5 and more new records, hopefully
