Terms

744 multiplexer

The part name for our detector's bare readout.

annealing

process for removing stresses in metal via heating

bare readout

detector without the infrared sensitive layer. It is sensitive to visible light and behaves the same electronically as the science detector.

cryo

G10 fiberglass

The type of fiberglass sheet used to thermally isolate the inside of the dewar.

Irshell

modal observer

model of telescope that predicts telescope bending given aero-acoustic loads. Used to correct image motion by moving torque motors and secondary mirror.

nodding

moving entire telescope between source+sky and sky

slew

rapid moving of telescope to new position
