Tunnel boring machine 1 (TULA = TUnnel for LAser) |
||
| Activity | After finishing the two tunnel sections between Schenefeld and Osdorfer Born (XTD1 and XTD2) at the end of December 2010, TULA started boring the main tunnel (XTL) in January 2011. This more than 2-kilometer-long tunnel between Osdorfer Born and DESY-Bahrenfeld is located under inhabited area. Its boring was completed on 6 August 2011. | |
| Length of completed tunnels | 100.0 % 3084 m of 3084 m | |
| – in current section (XTL) | 100.0 %2010 m of 2010 m | |
| Start date | 07 July 2010 | |
Tunnel boring machine 2 (AMELI) |
||
| Activity | AMELI is the German acronym for "At the end (there will be) light". It is the smaller of the two tunnel boring machines and drilled the "fan" of altogether eight single tunnels (XTD9, XTD10, XTD4, XTD8, XTD7, XTD5, XTD3, and XTD6) underneath the future Schenefeld research campus. The Boring of these tunnel sections was completed on 7 June 2012. | |
| Length of completed tunnels | 100.0 %2693 m of 2693 m | |
| – in current section (XTD6) | 100.0 %660 m of 660 m | |
| Start date | 11 January 2011 | |
