Text of Acrylic Tests

  • Acrylic Tests

  • These slides show the tests that are currently being done or are planned to be done on acrylic to determine some of its properties under different conditions.

    These tests will be useful in minimizing systematic errors in the detectors from the acrylic vessels.

  • Wet Acrylic BehaviorWere soaking acrylic samples in Distilled Water, Mineral Oil, and LAB.Simulates Filled AVsWere measuring their weights and dimensions to see how they increase with time.Were also measuring the transmittance of the acrylic pieces to see how it changes as the different liquids are absorbedThis is currently being done in the lab.

  • Data From Soaked Acrylic SamplesThese three samples had relatively the same weight and were each submerged in a different liquid.The samples weight in Distilled Water has increased ~ .4%The samples weight in Mineral Oil has increased ~ 1.6E-2%The samples weight in LAB has stayed relatively the sameThe other 2 samples that were in each liquid showed similar changes in weight.

  • These three samples had relatively the same length and were each submerged in a different liquid.The samples length in Distilled Water has increased ~ 4E-2%The samples length in LAB and Mineral Oil has stayed relatively the same.The other 2 samples that were in each liquid showed similar changes in length.The other dimensions of the acrylic samples have stayed about the same since they are so much smaller than the samples length.
