Hi Sir/Madam, I am doing simulation for gas cerenkov detector.
First I wrote code based on N06 example. And I saw the photons generated by electron were detected by pmt. And my purpose is to build an elliptical inner silver surface. However, I use 4 different geo and get 1 and 3 working, but 2 and 4 not. It seems it's associated with ellipsoid geometry. http://www.jlab.org/~hyao/pdf_files/question/
<--Code-->ckovDetectorConstruction.cc Please see the "Volume-->Spherical Mirror" Part of the code. It's very easy to trig 4 geo on or off.
<--Stepping-->1.Sphere1-Sphere0(sub_solid) working sphere-sphere.dat
2.Sphere1-ellipsoid0(sub_soid) not working sphere-ellipsoid.dat
3.Sphere(mother,silver)+Sphere(daughter,NitrogenGas) working sphere+sphere.dat
4.Sphere(mother,silver)+ellipsoid(daughter,NitrogenGas) not working sphere+ellipsoid.dat
<------------>Also you can make the file and check the result.
Is there any clue what happened?
Thank you very much.
