As you enter the LHCb secretariat office, you’ll arrive at the welcome desk where hand-gel and a sign-up sheet have been made available to you and you will have to wear a mask. We are obliged to record the names of everyone entering the office. We kindly ask that the 2m distance is respected.

Please note that the stationary cupboard will remain locked. If you need any stationary items, contact us and we will prepare everything you need. Then you will be able to collect the items at the secretariat.
