It was felt that the tilts needed to get similarity between simulation and RCF measurement was acceptable. Suggestion to return to consideration of modest shifts in (x,y) [i.e. perpendicular to beam axis]. Equally, it was recognised that it would not be possible to find a unique description of RCF since the system is under constrained with just the measurement of dose at the end of the beam line. * Suggestion to consider integrated simulated dose distribution for comparison with the optical measurement. This may show that the details of the shape in (x,y) is not spoken important. * Important now to take practical approach to get a simulation "good enough" to support the interpretation of the data in the paper. //Optical analysis: // * All felt the "Hobson cut" was the right way to develop the analysis and to look at the optical signal and optical/acoustic comparison as a function of the Hobson cut. * Agreed that plotting the correlation shot-to-shot of the integrated optical response (using the Hobson cut) with the acoustic response was likely to be the productive approach. This would also mean that a data/data comparison would be made making the reliance on the beam-line simulation less. //Paper goal: // * We agreed to try and get a good draft of the paper by Christmas 2025. ---- == Presentations == 1.
