Overview of EHN1

The beams enter from the bottom of the photo. Starting from left (Jura side)three experiments lay upstream of the European Hybrid Spectrometer (EHS), NA20, NA25 (with a small HOlographic Bubble Chamber, HOBC) and NA24. The EHS houses NA21, NA22 and NA23 with the Rapid Cycling Bubble Chamber RCBC, NA26, NA27 with the HOlographic LExan Bubble Chamber, HOLEBC. Along the beam line most at the right (H8) lays the NA3 setup, while downstream one sees the assembly of the GAMS detector (blue) of the CERN/USSR experiment NA12. At the centre run the beam H2/E2 for the FRAMM experiments NA1 (now completed), NA7 and NA29, and the beam H6 for NA30 and NA11.
