Re: LHCf Experment
A late, but hopefully helpful, answer: the LHCf provides better data for identifying Extremely High Energy Cosmic Rays (lab equivalent of 10^17 eV and up). Here's how I've understood it: * The problem: All we have on EHECRs ATM is theories based on whatever low-energy lab data has been gathered so f...

Losing vac in the PS, losing vac in the effing linac that's been running without a glitch for ages now, losing cryo, strange new QPS bugs showing up, injectors not injecting, kickers not kicking and now a power failure. Makes me wonder if there's something to the theori...

Re: What do the displays mean ?
SMP means "Safe Machine Parameters". EDMS 883620 lists (in a very roundabout way) the conditions under which each is true (except for Global Beam Permit, I guess that's a human decision). EDMS 810607 contains them too, along with other info (such as the locations of the detectors).
