MSE thermal birefringence and shot to shot reproducibility

MSE thermal birefringence and shot to shot reproducibility . Motivation: MSE has poor reproducibility in q measurements Last campaign we determined this was caused by birefringence in L2 from temperature changes throughout the run day (1080523) Bench experiments support this hypothesis.

  1. MSE thermal birefringence and shot to shot reproducibility • Motivation: • MSE has poor reproducibility in q measurements • Last campaign we determined this was caused by birefringence in L2 from temperature changes throughout the run day (1080523) • Bench experiments support this hypothesis

  2. Thermal Management MSE thermal shield L2 mount O-ring seat • Actions taken • New L2 mount to thermally isolate lens from the MSE canister • New heat shield for temperature control of entire canister • Proposal • A few identical shots throughout a run day to check reproducibility • Preferably run days with significant RF heating for worst possible thermal environment
