-
History of Ludlum @ Notre DameOngoingLudlum Measurements Inc. In the past, separate wave shifting and scintillating materials were used in combination with one another.
-
Current Focus of Ludlum @ NDCurrent experiments are focused on materials that are manufactured with both properties in a single fiber. Old 3HFNew 3HFOX-550F4CN-HBT
-
Current Goals of LudlumThe goal of the project is to find a material that can be used in new particle detectors. Several methods have been developed in the past and are in use at FermiLab and CERN currently.
-
Factors Tested This SummerBrightnessHow much light is transmitted along the fiberDecay TimeHow much time passes between excitation and relaxation of molecules in the fiberAttenuation LengthHow long can a fiber be before light begins to escape
-
Test Scintillation Used to test all three factors
-
Experiment Set Up within a light tight boxSr 90FiberPMT Counter PaddlesBrass plateApiazonRadioactive sourceData PMT
-
Experiment Set UpOptical fiberBronze plateRadioactive sourceTime- gate paddles
-
Data GatheringTwo paddles are used as triggersBrass plate shieldsRadioactive sourceData is stored on an oscilloscope2048 data points per run - averaged6 or more runs per graph - averagedSeveral distances from source to PMT
-
Data Gathering
-
Calculating BrightnessBrightness is a measure of how much light the fiber transmitsIntegration yields total lightSeveral integrations completed
-
Calculating BrightnessAverage brightness is 1021 units at 1.5 m.

ConclusionsPreliminary results indicateNew 3HF is the brightest fiber4CN-HBT has shortest decay time4CN-HBT has the longest attenuation lengthThe nature of future experiments will dictate which fibers will be usedThere may not be one perfect fiber
