Airmount & PALM Summary
Airmounts:
3 Airmounts
Isolates the Metroframe from the external world
Actively dampen oscillations of the Metroframe
Airmount stabilize Metroframe in X, Y, Z Position
Airmount air bearing delivers main force to carry Metro
Frame
Metro Frame position is determined by horizontal &
vertical Lorentz motors
PALM supports the lens and actively dampens lens
vibrations
SUCR is the Electronics rack for Airmounts & PALM

Safety
Every maintenance function has related safety items
Each procedure lists the safety hazards and warnings
possibly encountered when performing the procedure.
In addition, all common precautions that pertain to
working on TWINSCAN systems must be considered.
These include, but are not limited to, UV radiation,
Electrical, Magnetic fields, Mechanical and the safe use
of Solvents (IPA, Acetone).
Read a procedure all the way through before starting
Hazards that must be considered when performing each
procedure will be indicated with a symbol and a printed
warning.

Periodic Maintenance (PM) Twinscan training is
designed around the Yearly Periodic Maintenance
tasks.
For Airmounts and PALM no specific tasks are designed
Some non-PM related activities are defined for the PM
training and will be explained by your instructor.
