I recently focus on the response of BC501A detector. Anyway , I can't get the proper result. Following is a brief introduction of my simulation:
Particle source : 5.5MeV neutron energy; Detector : BC501A(5.08cm diameter, 5.08cm height) Physics : QGSP_BIC_HP/QGSP_BERT_HP/QBBC
The correct response ( after multiplying with the light output function for proton energy deposit) should be the distribution in attachment 1 . However , the response given by the simulation which I put in attachment 2 do not accord with that. Moreover, the tail of the simulation spectrum is really strange (same for 3 physics lists), I also can not figure why there 's so much counts after the maximum energy?
I was wondering if anyone can help me out of here. Thank you in advance , any help will be appreciated.
