  1. NSW envelopes New Small Wheel 15/02/2013 M. Ciapetti - G. Spigo

  2. Hub Brass pins will be inserted into the hub to improve the spokes bending behavior

  3. Hub Brass pins will be inserted into the hub to improve the spokes bending behavior

  4. Main structure IP IP LS SPOKES SS SPOKES FEET SPOKES

  5. Full assembly LS SS IP IP LS SPOKES SS SPOKES FEET SPOKES

  6. LS spokes LS spokes have been fortified and adapted to the current alignment bars

  7. NSW assembly envelope

  8. Sectors envelopes radial size Referring to what has been presented on 01/02/2013 regarding the radial dimensions of the sectors, due to the NSW (slightly) different position in z, these dimensions have been (slightly) changed: This means that to cover the desired h range (1.3 ÷ 2.7), the effective detecting area must have the following radial distances from the beam axis: Small Sectors: from 927mm to 4383mm (zmid SS = 7261.5mm) Large Sectors: from 953mm to 4628mm (zmid LS = 7676.5mm) Assuming a 30mm thick wedge assembly frame, the large sectors should be extended ≈10mm towards the EIL4 chambers

  9. Large Sector envelope This cut is necessary TO BE CHECKED sTGCs are 59mm shorter than the envelope out of h range The envelope has changed slightly

  10. Small Sector envelope Only 27mm from the spoke  CRITICAL Only 3mm from the spoke  CRITICAL sTGCs are 121mm shorter than the envelope out of h range
