Length Metrology Week: October 19th - 23rd, 2026, at NPL
with NanoScale from Tuesday, October 20th, to Thursday, October 22nd.
Here is the detailed NanoScale programm with all talks, posters and their arrangement, lab-tours and the excursion! You may need to push the refresh-botton of your browser to see the latest version.

Similar to 2019 in Braunschweig and 2023 in Helsinki, NanoScale 2026 will be embedded in a Length Metrology Week, with some Working/Task Groups of the BIPM Consultative Committee for Length (CCL) meetings before/after NanoScale 2026. These meetings of BIPM CCL sub-groups are for delegates only, while NanoScale is open (but registration required - closed 2026-10-12).
Unlike back in 2019 and 2023, EURAMET TC-Length, however, met separately at METAS in Bern, Switzerland, already in the beginning of October 2026, as it was largely felt that the Length Metrology Week might otherwise get too packed and too busy for many delegates.
This allows us to avoid any parallel sessions in the Length Metrology Week at NPL in Teddington and ensures that all delegates can attend all meetings.
Please understand that tight security rules are in force at NPL due to the increased international confrontation: Please do not forget to have your passport ready whenever entering NPL. Only the original paper documents are accepted, no scans, no copies, no digital formats on your phone. Admission is only allowed with proof of ID and after advance registration. Such ID checks are required whenever you enter NPL (again), so also on the 2nd and 3rd day: Please arrive early around 08.30 on the 2nd and 3rd day, maybe enjoy a coffee or tea and be sure not to miss the beginning of the sessions.
Do the tight security rules, spontaneous access to the NPL premises without prior registration is not possible. For NanoScale, please register via the web interface to be sure that your personal data is forwarded to NPL well in advance to grant you access.

Tuesday, October 20th, 2026
Please access the NPL premises via the main entrance at Hampton Road and have your passport ready upon entry. There is a left luggage storage at NPL reception.
Check-in will open Tuesday morning around 10:00 to allow a smooth check-in, to put up the posters and have some first smalltalk with fellow attendees.
Lunch (included in the conference fee) will be served at 12.00
Sessions are scheduled to start after lunch at 13.00.
After the end of sessions, we will directly proceed together across the NPL campus to the reception in Bushy House. Please take your belongings with you, as we will not return to the lecture hall that evening, and stay with the group as requested by security.
A reception (included in the conference fee) is planned in the famous historical Bushy House for Tuesday evening as a relaxed get-together with drinks and food (no need to go to a restaurant afterwards any more!). After the reception, we will leave the NPL premises from Bushy House through a side exit (no return to the lecture hall and main entrance).
Wednesday, October 21st, 2026
Please check in (with passport again) early, possibly around 08.30...08.40.
NanoScale sessions will continue at 09:00 on Wednesday, with a common lunch (included in the conference fee) at noon.
In the evening, you are invited to join the Excursion with Conference Dinner! It is also included in your fee. Get surprised - only the NPL orga teams knows where we are going!
We will directly leave by chartered coaches from NPL right after the closure of sessions. The excursion includes a guided outside walk of ~45 minutes, followed by a reception and the dinner. The coaches will take you back to NPL and the hotels in its neighbourhood.
Thursday, October 22nd, 2026
Please check in (with passport again) early, possibly around 08.30...08.40.
NanoScale sessions will continue at 09:00 on Thursday, with a common lunch (included in the conference fee) at noon.
After the closure of sessions, lab tours will be offered Thursday afternoon. We will form six groups (12 attendees each), please follow the announcements during the conference. The number of participants in the lab tours is limited to a total of 72. You can leave bags in the reception and collect them after the lab tours.
- The size of the posters will be A1 (!), that means 594 mm wide and 841 mm high. Please not that this is half of the size A0 we had at previous conferences. Posters will remain on display on the boards throughout the conference so that they can always be visited, e. g. in the tea/coffee/lunch breaks and before/after sessions. There will be two poster sessions of at least 90 min each, with at least one author present to answer questions.
- Lab-tours for NanoScale attendees are scheduled for Thursday late afternoon (as shown above). Already on Tuesday, we will need to define the groups for the lab visits, as the lists need to be approved by the NPL security. Once the lists are fixed, we cannot add further names.
- There will be several tea/coffee breaks (included) for refreshment during the sessions days.
