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

Some things can be done before coming to CERN and that is strongly recommended, unless you enjoy going from building to building for a couple of days.

A computer account. Register with the LHCb secretariat There are 2 distinct accounts with, if you wish, different passwords:

  • NICE-account for Windows computer park
  • account for Linux machines

Recently there is a third one for computer work in the pit behind the firewall of LHCb, the so-called on-line network. Info: But first you have to get yourself a general CERN-account.

Before actually coming to CERN you should get yourself a couple of official papers, like copy of your contract from your university and a signature from your team leader on the "User registration form". It is all described in: Be sure to have them all, otherwise you will never get passed the next step: the User Office.

Once having arrived at CERN, your first acquaintance with bureaucracy will be the User Office. Location and opening hours at:

If all your papers are correct they will direct you to building 55 next to the main entrance to get your CERN-id.

If you want to get access to the pit you then have to take the following actions:

  • The most tricky point is to get the actual access authorisation to the pit. This has to be requested via EDH. (for info see Web-site above) Problem is that some people need to give permission, which can take up to a day. But then this new info has to uploaded to the checkpoints which might take another day. But no guarantee whatsoever. If you want to do it as quickly as possible, best is to pass immediately after the safety course by the LHCb-secrtariat and explain to Natalie that you came to CERN to work on the experiment and do not want to drink coffee for 2 days before you get officially authorised to work in the pit.

  • The LHCb-secretariat has a couple of visitor passes with which you can get access to the pit if accompanied by a qualified person, but these are NOT meant for people that have to work in the pit.

  • Once you have the 7h/19h working day access to the pit, you can get yourself an upgrade to 24/24 for 7/7. Select in EDH, under "Access Request", "Click to add a new line item", "LHC Installation Special Hours (LHCI-24)" and after 2 days you can also work at evenings and in the weekend.

  • Following the Level4 safety course is strongly recommended, although not yet obligatory. The course is available on the Web. For those of you who can access the AIS system it may be reached via: But you first have to be registrated and have an AIS-account otherwise you can not effectuate your graduation from the exams. (Oxygen deficiency and electrical)

  • 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 in Meyrin, to get this extra feature implemented.

Don't bother about dosimetry (yet).
