Collimator R&d Collimator R&d
The importance of collimator R&D with test beam facilities is demonstrated with the example of ILC collimator studies at SLAC End Station A. Related LHC collimator aspects and longer term plans are addressed. Presented at IDTB07, ILC Detector Test Beam workshop, Fermilab, USA, 2007.
متن کاملDiverging Opinions
People often see the same evidence but draw opposite conclusions, becoming increasingly polarized over time. Prior discussions of this puzzle have focused on the failure of Bayesian reasoning or on the possibility of non-common priors. By contrast, we offer a model of diverging opinions in a Bayesian environment with common priors. In our model, people hold different private information and dis...
متن کاملTIR RXI collimator.
A metal-less RXI collimator has been designed using the Simultaneous multiple surface method (SMS). Unlike conventional RXI collimators, whose back surface and parts of the front surface have to be metalized, this collimator is completely metal-free, made only of plastic (PMMA). The collimator’s back surface is designed as a grooved surface providing two TIR reflections for all rays impinging o...
متن کاملCollimator Technology and Advancements
The single-hole collimator limits the field of view of a scintillation probe to a single organ. The sensitivity for counting is approximately equal over the entire field of view. The most common use of this collimator is for iodine uptake measurements of the thyroid. An example of this "flat-field collimator" is shown (Fig. I). The sensitivity profile at the working distance illustrates the rel...
متن کاملAdvanced Collimator Prototype Results for the NLC
The Next Linear Collider accelerator will include a large (kilometer scale) and complex collimation system. The size and complexity of this system could be reduced if the collimator jaws could be made immune to damage from the electron beam. We describe two collimation systems currently under development. Construction of a prototype system which uses wheels that can be moved to a new position a...
