A service tunnel is above the 1000 mm steel shield quadrupoles 1 a, 1 b, 2 rods for vertical adjustment (Z 3, Z 1) rod for horizontal adjustment (transverse beam direction, Y) Quadrupole 2 rod for vertical adjustment (Z 2) Quadrupole 1 a sextupole dipoles gear for horizontal adjustment sextupole gear for horizontal adjustment angle gear Dipoles Dipole coil manufacture Quadrupole 1 b rod for horizontal adjustment (along beam direction and yaw, X 1) lifting gear strut for adjustment along beam direction and yaw rotation (X 2) • One dipole already exists. Two further dipoles are ordered • New adjustable support frame for the dipoles. Horizontal adjustment is based on a 3 -strut system. Successful test => same type of support frame for all other magnets and beam catchers • Connections for water cooling and electrical current have been successfully tested one month at full power. Dipole yoke manufacture MIC strut for adjustment transverse beam direction (Y) strut for adjustment along beam direction and yaw rotation (X 1) • All three quadrupoles have a different design. Special coil configurations are required.
