EXCEPTIONS
January 10th, 2023: not visits to the underground or exhibition
How to organize a visit (Underground or Exhibition area)
The first step is to send an email to lhcb-visits@cern.ch,
precising date, time, total number of participants (visitors +
guides). We will then be able to inform you if your visit can take
place or not. For all visits (Underground or Exhibition area), an
impact form will be created by the LHCb secretariat.
Due to the high number of requests, it is recommended to plan
visits well in advance.
A visit to the underground area (Delphi and/or LHCb) of Pit 8 would be allowed providing that:
It is given by an LHCb guide who
1a) has the required access authorisations (see Access
to Experimental Site on the LHCb homepage)
1b) has been appointed
as guide. See details on how to become an LHCb guide (to contact the
LHCb guides click HERE).
An Impact form for the
visit has been submitted by the secretariat and approved.
The number of visitors per guide does not exceed
12. Additional restriction applies if minor are present
(See
here for details)
At the beginning of the visit the guide reminds visitors of the safety measures (you can find them and print them from here)
During the visit, the LHCb guide must be equipped
as follows:
- wear an helmet
- wear a working head light or carry a working flash light
- wear safety shoes (shoes and flash lights are available at the
control room, if needed)
- carry a mobile phone (the phone number must be entered in the
Impact form)
- carry own personal dosimeter (it is recommended to read the
dosimeter before going underground)
Tokens and biometry keys can be retrieved shortly
before the visit from the key cabinet in the control room next
to the printers.
The cabinet can be opened with the guide's CERN access card and
a movie on how to do it is available on the Escort
appointment web page.
At the end of the visit, the tokens and biometry keys should be returned in the same slot of the key cabinet by the guide
At the end of the visit the supervisor has to fill the report information in the visit report (see "After the visit" in the guidelines)
The visit can be cancelled on short notice for operational or safety reason
Safety rules applying to all visits at Pit 8 without exception
Persons equipped with any of the
following: pacemaker, defibrillator, electronic medicine dispenser,
hearing aid, metal implant, are not authorised into the undeground
area, unless the dipole magnet remains off during the visit.
Each visitor must :
wear a safety helmet (available in SX85)
be equipped with closed shoes (no high heels, sandals, closed sturdy shoes etc.)
stay with the group and must not wander around by himself (herself)
