1 ALIGNMENT NOTES
2 Electrical/Computer XY-Tables Controlled by a computer with parallel 25 pin D-connector interface (Laptops don t have this connector) Need a long cable routed outside the cave Need to install PCI card on the back of one of the nHe-3 computers to operate XY-Tables
3 XY Tables Dimensions of XY Tables: Large Table: Length: 50.5 inches Height(From floor): 49.5 inches Small Table Length: 26 inches (Not including end mounts) Height(From floor): 29.25 inches
4 Two Mounts on Large XY Table Extra Mount?
5 Mount for Small XY Table
6 Cabling for XY Tables Power cable for beam monitor (Battery operated) Signal cable from beam monitor to pre-amp Power Cable for preamp Signal cable from pre-amp to DAQ Power/Signal cable from XY table to Computer
7 Placement for small XY table?
9 Laser Beam Melles Griot: Class 3b 633nm CW Beam emitted at both ends Outputs 4mWatts at each end Beam is ~1/8 inch diameter at close range Safety Requirements apply
10 Mount for Laser Beam Newport Model 39 Two-axis tilt platform -3.5 to 14 degrees on long axis -5 to 16 degrees on short axis
11 Mount for Laser Beam Newport model 460P 90BK 90 degree angle bracket Newport DS40-XY linear stage 0.55 inches travel in both directions
12 Determine Beam Centroid X1,Y4 X1,Y1 Data points are ordered triples: Beam Centroid Determined from data from large/small xy-tables:
13 Beam Centroid Need a plan for taking data points 4 Jaw Collimator Square hole aperture
