Preliminary Installation & Alignment Plans

Align Grouting Plates at Lattice Locations – Available Adjustment ± ½” (12.7 mm)

5


Anchor Grouting Plates at Lattice Locations

6


Add Grout under Grouting Plates at Lattice Locations

7


Rough ±5mm position Support Stands on Grout Plates– Final position later from MMR numbers

8


Fill Support Stands– Add Silica sand to stand pipe– Cap Stand with Cap Plate– Add 3” Fiber wool Insulation to stand

9


Magnet Measurement Room Loosely attach CAM Movers to CAM Support Plates using the alignment

grooves that utilizing the tight machined tolerances of the CAM Housing

10


Magnet Measurement Room Position Girder on CAM Movers to Specifications Required

– Secure CAM Movers to CAM Support Plate– Record dimension between CAM Support Plates for use in final stand positioning

11


Precision position Support Stands on Grout Plates using dimensions obtained from MMR measurements and CAM Mover Support plate grooves.

12


Final Installation Using dimensions obtained from MMR measurements position CAM

Mover Support plate sub-assembly on support stands and precision position using plate mover mechanism.

13


Final Installation Install Undulator Assembly on CAM Movers using Girder Cart.

14


Final Installation Remove CAM Support Plate moving mechanism and install

Earth Quake Restraints

15


Elevation Adjustment Guides Elevation adjustment guides are to be installed prior to lifting

the support for height adjustment.

16


Elevation Adjustment Guides After the Elevation adjustment guides are installed the Air

Jack system can be used to remove most of the weight from the stand.
