The CCDs and their associated signal chains have readout noise levels (in the absence of signal shot noise or interference) of approximately 5e - . The analog-to-digital converter is highly accurate, and makes virtually no contribution to the read noise, other than the normal information loss caused by digitization of the signal. ... Note that all calculations of sensitivity in this manual assume gains of 7 and 14 for two gain channels, choices very close to the measured gains. ... 0.41 . ...

... 7a. Fluorescent lamp . ... Plasma is sometimes called "the fourth state of matter", beyond the familiar three--solid, liquid and gas. It is a gas in which atoms have been broken up into free-floating negative electrons and positive ions , atoms which have lost electrons and are left with a positive electric charge. ... The hotter the gas, the faster its atoms and molecules move, and at very high temperatures, the collisions between such fast-moving atoms are violent enough to rip off electrons. ...
