TITAN's MCP's & restrictions in Polarizer
MCP locations (& how to diagnose whether they're blocking beam); adjustable collimator locations in Polarizer
1. between ILE2T:YCB4 & XCB5
2. ~ between ILE2:Q13/14
3. post-deflection plate ILE2:DEF15C & FC15
default position is 'out' of beamline (i.e., if you disconnect the compressed air) corresponding to red plunger 'in'
*note this is counter-intuitive*
two adjustable collimators (open, 3mm, 1mm) were installed post-Na cell, before solenoids
