[Halld-physics] threshold Cherenkov simulation, photocathode Q.E. curves

[Nathan Sparks]

Hello Eugene,

Could you send me the photocathode Q.E. curve that you used for the quartz PMT in your simulations? Currently in hdds there is a curve for a Cesium photocathode which looks quite different from the ones shown in your Cherenkov Simulations March 2007 talk, slide 17; the Cesium curve has low ultraviolet coverage, which may account for the smaller average number of photoelectrons seen in my simulations.

Thanks,
-Nathan
