Answer
|
- How much maintenance is required
|
- None, turn it on and forget it.
|
- Do you have to retune the SCxx if the field levels change?
|
- No. The system reacts dynamically to changes in field level.
|
- How quickly do these systems react to changes in field?
|
- They react in 100 microseconds or less. But note that the AC RMS meter on the
front panel cannot show this performance because it has a fast-attack,
slow-decay characteristic.
|
- How are the cables installed
|
- Room size cables are attached to the wall by tie-wrap anchors or
plastic molding. Alternate cable sets and installation methods are
also used. in some cases the cables are installed under the floor or above the
ceiling.
|
- How large are the cables?
|
- The standard room coil
lengths are 16m in X and Y and 20 in Z. The make a complete loop around
the room and connect back to each other. Custom cable sets can be
provided on request.
|
- Do I need a Helmholtz frame?
|
- Not usually. Helmholtz cables are inconvenient for the user and no
better than room size cables for canceling beam movement. They are typically
used for OEM installations when other cable arrangements are not suitable.
|
- Will one system cancel all the fields in a room with multiple
tools?
|
- separate systems are required for each tool.
|
- Can I install two SCxx systems side by side?
|
- Yes, but precautions are necessary. Call us to discuss this if it's
an issue.
|
- If I install an SCxx on one tool, do I need one on the next door
tool?
|
- Sometimes. It depends on the individual circumstances.
|
- Do the trip levels affect canceling?
|
- No. They only affect the level at which the Field OK light goes out
and the trip indicators come on.
|
- do these systems cancel the effect of lifts (elevators)?
|
- The SC-20 with optional DC sensor(s)
will.
|
