3. SM18 as a R&D magnet lab: 1992 – 1998
The SM18 Test Hall has been early associated with the LHC project:
1992 – 1993: Construction of the 2 first benches to test 10 m long LHC dipole prototypes.
1996: Construction of 2 new benches to test 15 m long LHC dipole prototypes.

4. SM18 as magnet production test: 1998 – 2007
From 1998 until June 2004:
Construction of the infrastructure for the 12 benches
Preparation for the LHC magnet production test (HW & SW)

5. SM18 as magnet production test: 1998 – 2007
From 2003 to February 2007:
More than 100 people were working in SM18
3 shift teams
12–14 magnets tested per week
~ 1 week per magnet

6. SM18 as magnet production test: 1998 – 2007
LHC main magnets were produced in 4 firms:
- NOELL (Germany, Zeitz & Würzburg)
- ALSTOM (France, Jeumont & Belfort)
- ANSALDO (Italy, Genoa)
- ACCEL (Germany)
Final assembly in building SMA18

32. The GSI-FAIR Project
The Super-FRS is a two-stage in-flight separator to be built next to the site of GSI, Darmstadt, Germany, as part of FAIR (Facility for Anti-proton and Ion Research).
Its purpose is to create and separate rare isotope beams and to enable the mass measurement also for very short lived nuclei.
