According to an aspect, a UV radiometer is provided. The UV radiometer includes a sensor assembly and a sensor controller. The sensor assembly includes a UV sensor element and a temperature sensing component configured to perform a thermal adjustment of a sensed UV input from the UV sensor element to produce a compensated UV signal. The sensor controller includes a signal conditioning circuit configured to receive the compensated UV signal from the sensor assembly and produce a conditioned and compensated UV signal. The sensor controller also includes a communication interface configured to transmit the conditioned and compensated UV signal to a UV process controller.

Ultraviolet radiometer

Certain embodiments described herein are directed to devices that can be used to align the components of a source assembly in a source housing. In some examples, a terminal lens configured to couple to the housing through respective alignment features can be used to retain the source components in a source housing to provide a source assembly.

Assemblies for ion and electron sources and methods of use

There is provided a method for limiting an operating speed of a rotor installed in a centrifuge system. The method includes the steps of (a) determining whether an actual change in energy required to accelerate the rotor from a first speed to a second speed is within a predetermined range of an expected change in energy required to accelerate the rotor from the first speed to the second speed, and (b) limiting the operating speed when the actual change in energy is not within the predetermined range of the expected change in energy.

Method for energy management and overspeed protection of a centrifuge

A method for limiting an operating speed of a centrifuge rotor includes the steps of determining whether an actual parameter value of the rotor is within a predetermined range of an expected parameter value of the rotor, and limiting the operating speed when the actual parameter value is not within the predetermined range of the expected parameter value. At least one of the following parameters is evaluated: (i) energy required to accelerate the rotor from rest to a predetermined speed, (ii) change in energy required to accelerate the rotor from a first speed to a second speed, (iii) energy loss due to windage of the rotor, (iv) time required to accelerate the rotor from a first speed to a second speed, (v) speed of the rotor at a predetermined time, and (vi) ratio of drag coefficient and inertia.
