Proton Calorimetry/Experimental Runs/2018/FebScintSheets

The thickness of 50 scintillator sheets provided by Nuvia were measured using a digital caliper.

Measurements

The measurements were added to an excel spreadsheet and converted to a comma delimited file for analysis using a python script.

• All of these files can be found at:

/unix/pbt/wikiData/data/ScintillatorSheetThickness

Before painting and any measurements were made, the sheets were divided into a group of 30x2mm sheets and a group of 20x3mm sheets. However, the 2mm group was found to be split evenly between an average thickness of 2mm and an average thickness of 2.6mm. These regimes are displayed in the histograms below.

The data can be summarised in the following histograms:
