Daughter ion spectra with time-of-flight mass spectrometers

The invention relates to time-of-flight mass spectrometers for the measurement of daughter ion spectra (also called fragment ion spectra or MS / MS spectra) and corresponding measurement methods.According to the invention, the ions of an ion source are initially accelerated only to an intermediate level of energy, allowing them to decompose at that energy level by metastable decomposition or by collisionally induced fragmentation (CID). The ions are then accelerated in a second step to a high energy level. Light fragment ions gain a higher velocity than heavier fragment ions or non-decomposed parent ions. The spectrum of fragment ions can be detected separated by mass in either linear or reflector mode. An ion selector at the low energy level selects a single type of parent ion in order to avoid superpositions with fragment ions of other parent ions. A particularly preferred embodiment raises the potential of ions, for there second acceleration, during their flight through a small electrically isolated flight path chamber.

Method for calibrating a lighting control system that facilitates daylight harvesting

One embodiment of the present invention provides a system for calibrating a lighting control system. The lighting control system is a daylight-harvesting system that controls the output of the lighting system based on available daylight and / or other light sources to reduce energy usage while providing lighting for an area. The lighting system includes multi-level lighting capabilities for one or more light sources. First, the system measures the light levels for the area when the lighting system: is turned on at a high energy-level; is turned on at an intermediate energy-level; and is turned off. The system determines from these measured light levels the light output of the lighting system in the different states. Then, during operation, the system measures a present light level for the area. The system then adjusts the light output of the lighting system for the area based on a lighting control parameter (e.g an on set-point and an off set-point pair), the present light output of the lighting system, and the present light level for the area.
