Access to the LHCb cavern
1) Get the necessary safety training
In addition to the general mandatory courses you need to follow the courses below to be able to access the UX85 cavern:
- Radiation Protection - Supervised Area
- CERN - Beam Facilities
- CERN – LHC Large Experiments
- LHCb - Surface and Underground areas
These courses are web-based and available at
https://lms.cern.ch.
If your
training and access ranks are still valid (check via
adams.cern.ch) you do not need
to take the above courses until the expiration of your access rights
approaches.
If you need to access the VELO alcove, the area close to the beam
pipe between open calorimeters or the adjacent LHC Tunnel,
you will have to take an additional half-day classroom
course
Radiation Safety - Controlled area – Initial.
If you already
had this training rank, but took the course more than 3 years ago,
you only have to enrol for the online
Radiation Safety – Controlled Area – Refresher.
When redoing courses for the renewal of your access rights, it is possible that additional online courses may be required by the new learning platform. These will be indicated to you by the platform when you try to enrol to the course. If you encounter any problems while trying to take these courses, please open a ticket at the CERN Service Portal by clicking on the “Contact: Safety Training” link on the course page.
If you need to work at a height of 8 m or more above the cavern floor (e. g. on the calorimeter gantry) you need to follow the classroom-based course Self-Rescue Mask.
2) Submit an access request for "LHCb_U (UX85: LHCb underground)"
via "Request access" on the left-hand menu of adams.cern.ch.
At the same time, request an access authorization for LHCb_S (LHCb surface buildings).
If it is your first request, send a copy for information to your project leader and mention your project (VELO, Muon, etc.) in the comments.
3) Obtain a dosimeter
Go to Building 33 to get an individual dosimeter and activate your biometry.
4) Submit an IMPACT request
https://impact.cern.ch/impact/secure/
Explain who intends to do what, how and when.
Access will be granted only once the IMPACT is approved and for the duration of the task.
Access to Point 8 surface buildings and the control room
Submit an access request for LHCb_S (LHCb Surface Buildings), providing a meaningful justification (e. g. "LHCb Shifts" or "LHCb piquet").
Access to the SXL8 assembly hall
If you need to work in the SXL8 assembly hall (building 3852), submit an access request for 3852-R-001 (LHCb_Facilities 3852), providing a meaningful justification. You do not need this access request for control room shifts or for working in the cavern.
