PhotoMultiplierTube

Bases: PointDetector_Type

Represents the XML element PhotoMultiplierTube.

A Photomultiplier Tube (PMT) is a photoemissive device in which the absorption of a photon results in the emission of an electron and it is used for the detection of very weak signals. These Detectors work by amplifying the electrons generated by a photocathode exposed to a photon flux. The higher the supplied voltage (PMTVoltage setting), the greater the amplification of the current (PMTGain setting) and thus sensitivity, but also the higher the noise in the acquired image. The amplifier offset (PMTOffset setting) defines black level setting of the image. A PMT has no inherent spatial information of the image.

setCollectionEfficiency(value)

Sets the value of the CollectionEfficiency attribute.

This field measures the probability that photoelectrons will land on the effective area of the first dynode of the photomultiplier stage. While there might be dispersion at the second and later dynodes, this tends to have less of an effect on the total collection efficiency as the number of emitted electrons increases greatly.

Name	Type	Description	Default
value	PercentFraction_Type	The value to set	required

getCollectionEfficiency()

Returns the value of the CollectionEfficiency attribute.

This field measures the probability that photoelectrons will land on the effective area of the first dynode of the photomultiplier stage. While there might be dispersion at the second and later dynodes, this tends to have less of an effect on the total collection efficiency as the number of emitted electrons increases greatly.

Returns:

Type	Description
PercentFraction_Type	The value of the attribute

resetCollectionEfficiency()

Resets the CollectionEfficiency attribute to an unset state.

This field measures the probability that photoelectrons will land on the effective area of the first dynode of the photomultiplier stage.
