Below some hopefully helpful info for new collaborators that also need access to work in the pit (=IP8) of LHCb.

There is "official" information from CERN http://ph-dep.web.cern.ch/ph-dep/UsersOffice/AccessAuthorizations.html

You need to do both Level 4 AND 4b and pass them (it is possible to fail!!!). There are specific risks relevant to the VELO area, even in the D3 barrack.

 
  • To get access to the LHCb control room (on the ground floor at IP8) Bernard Corajod, who is most of the time at the pit, has to give authorisation. If he has done so, you have to go with your CERN-id to Building 124 (124-R-011, Sebastian Auerbach) in Meyrin, to get this extra feature implemented.

Dosimetry is not yet obligatory. But soon will be. Please attend the appriopriate radiological protection course which is obligatory if you plan to get a film badge. Follow this link to find out how to register

Please note that working around the beam pipe requires special precautions

Please note that working around the beam pipe or the magnet requires permission. Ask if you don't have any or are unsure contact Themis Bowcock or Eddy Jans for further information.

  • Don't forget that you are obliged to wear safety equipment which INCLUDES steel capped shoes and a hard hat with lights. These are available from the store.
 
  • In general the beam pipe is very fragile, and surrounded with fragile sensing equipment. Do not approach it, not touch it, and certainly not drop anything on it! Remember that upstream of the VELO the beam pipe is relatively strong and well attached, but downstream from the VELO exit window it relies only on the protection which has been installed, and which may be incomplete in places.
Line: 79 to 89
 
  • Note that, under normal circumstances, the evacuation of the beam pipe is an infrequent occurence, but will occur at least one more time before the startup.

  • In conclusion: the work around the VELO has for safety reasons to be closely coordinated. If you plan to work around the VELO please make sure that you contact Paula Collins (Paula.Collins@cernNOSPAMPLEASE.ch, +41764870411) or Eddy Jans (eddy@nikhefNOSPAMPLEASE.nl, +31206922085 or +41764872192) to receive their OK and possibly additional safety instructions.
